Lassa Outbreak in Nigeria..Months and counting

Medic-ALL (01-25-2016) DISEASE

by Kayode Kuku

Just less than 2 years after the Ebola virus hit the Nigeria and other countries in the West African region, Lassa fever, another viral hemorrhagic fever, with similar symptoms as Ebola broke out in the country.

Lassa fever is an acute viral illness first discovered in Nigeria in 1969 when 2 missionary nurses died from the disease. The virus was subsequently named after the town in Borno State, Nigeria where the first cases occurred. The virus belongs to the virus family, Arenaviridae, a single stranded RNA virus which is animal borne and usually associated with rodent transmitted diseases in humans.

It is endemic in parts of West Africa including Sierra Leone, Gambia, Liberia and Nigeria notably but the risk is spread throughout the region where the disease vector, the multimammate rat (Mastomys Natalensis) is distributed.

Lassa virus is transmitted to humans by contact with excreta or urine of infected rats.

Lassa virus is transmitted to humans by contact with food or household items which have been contaminated with excreta or urine of infected rats. Since the disease is endemic in rodent population, it tends to affect communities with poor sanitation and crowded living conditions the most. Hence it is sometimes referred to as a "disease of the poor".

The present outbreak of Lassa Fever broke out in Nigeria, August 2015 and reports show that it has claimed up to 63 lives as at the January, 24, 2016  out of over 200 suspected cases spread across 17 states in the country including the Federal Capital Territory, Abuja. Nigeria's Health Minister, Professor Isaac Adewole, stated that 212 suspected cases have been reported in the last 3 months.

While the world's most populous black nation was praised for its prompt containment of Ebola in 2014, things appear a little more complicated in the case of Lassa , as many stakeholders including specialists have raised concerns ranging from ignorance of the disease among the vulnerable communities, leading to under-reporting of the cases and under-mining the scale of the outbreak  , and even the capacity of the country's healthcare system to deal with the outbreak at this time.

These are valid concerns, considering the "skeletal" state of the country's primary health care system and the lack of access to adequate health care in the vulnerable regions. The country reported 112 deaths and over 1700 cases of Lassa fever in 2012, yet in a population of over 170 million people, there is only one research center in the country to cater for Lassa fever research.

As far as comparison with Ebola goes, Lassa fever is not necessarily as deadly, but it spreads faster.

Meanwhile, while Lassa fever has exposed the level of preparedness of the nation's health care system to cope with such outbreaks, the WHO and US CDC are working with Nigeria Health Ministry in containing the outbreak.

Is Sex Bringing Ebola Back?

Medic-ALL (03:29:2014) -DISEASE

Its been a year long outbreak of the deadly Ebola virus and whilst the whole world looked back at the losses and lessons from the epidemic this past year, the virus appears to be making an unheralded comeback.

On Friday, in Liberia (one of the hardest hit countries alongside Sierra Leone and Guinea) , a 44 year old victim of the deadly virus was reported dead. There are indications that the new case may have occured via sexual transmission from a survivor she was said to be dating. Additional tests are being carried out to confirm this.

Research has shown traces of Ebolacan remain  in the  semen of some survivors for at least 82 days after the onset of symptoms. There is no conclusive scientific proof these traces are infectious. But anecdotal evidence in the latest case, and several others in West Africa, along with and confirmed transmission of Marburg, another viral hemorrhagic fever, have led experts to warn of the potential risk of sexually transmitted Ebola.

The World Health Organization, as a precautionary measure, advises Ebola survivors to abstain from sex during a 90-day period following recovery. At the very least, they should practice safe sex.

The case threatens to undermine the country's efforts to end a year long outbreak which has claimed over 10,300 lives across the African continent.

The country was on it's way to completing a 42-days period without a new case of the disease, which is necessary to declare the country free of the disease when it recorded the recent case.

Ebola continues to spread in Africa, though not as bad as it was some months ago. 79 new cases were reported last week. 

Though, it was known that Ebola was largely transmitted through body fluids of close contacts, no case of transmission via sex had been previously documented.

Record Drop in Ebola Cases since June

Medic-ALL (01:29:2015)

The health world continues to get the better of the deadly Ebola virus disease with latest reports showing a significant drop in the number of cases of the disease since June, 2014 when the disease began ravaging parts of the African continent  (where many of the countries initially affected have now been declared Ebola-free) and later spread to other parts of the world including the United States and parts of Europe. This Cable News Network (CNN) report puts in perspective the road to achieving this decline in the number of cases of the deadly virus particularly in the largely affected nations of Guinea, Sierra Leone and Liberia.

Ebola: West African Nation Declared Free

Medic-ALL (01:18:2015) Healthcare News-

Ebola virus stopped in yet another West African Country

The Government of the West African nation, Mali today declared the country free of the deadly Ebola virus following a 42-day period without a new case of the disease.

Mali's Health Minister Ousmane Koné declared this in a statement in which he thanked the country's health workers and international partners for their work which helped to see a halt to the outbreak.

Countries must report no new cases for 42 days - or two incubation periods of 21 days - to be declared Ebola-free.

Mali recorded a total of seven deaths caused by the Ebola outbreak that began just over a year ago

According to World Health Organization (WHO) data the worst epidemic of the viral haemorrhagic fever on record has killed more than 8,400 people, mostly in neighbouring Guinea, Sierra Leone and Liberia.

At least 21,296 people have so far been infected with the virus worldwide.

Mali's last infected patient recovered and left hospital early last month. At one point health officials had been monitoring more than 300 contact cases.

Mali became the sixth West African country to record a case of Ebola when a two-year-old girlfrom Guinea died in October. It was close to being declared Ebola free in November before a second wave of infections.

The country now joins other West African countries Nigeria and Senegal who had been declared Ebola-free in the last couple of months.

Ebola Response On Track -WHO

Medic-ALL (19:12:2014) Via MedPage Today

The response to the Ebola epidemic is on track to meet U.N. targets, the World Health Organization said in a mildly optimistic midweek situation report.
By New Year's Day, the agency said, the three hardest-hit countries will likely have the capacity to isolate and treat all cases and to bury all Ebola victims "safely and with dignity."

Guinea, Liberia, and Sierra Leone all now have more available beds than reported patients, the WHO said, although they are not distributed evenly and some regions still have "serious shortfalls." By the same token, each country has enough safe burial teams to handle all people known to have died from Ebola; however, some regions might lack enough capacity.

The U.N. goals are to have 100% of new patients under treatment by Jan. 1 and all known Ebola victims buried safely. Isolating patients breaks the chain of transmission, while safe burials -- avoiding unprotected contact with the highly infectious body of an Ebola victim -- avoid an important risk factor for new cases.
The agency also had a brighter picture of the incidence of cases, suggesting there are signs that the epidemic in Sierra Leone might be starting to slow -- even though the country reported 327 new confirmed cases in the week ending Dec. 14.
Most of the cases are in the western part of the country, with the capital, Freetown, accounting for 125 of the new cases. Teams began house-to-house searches in Freetown yesterday, seeking hidden Ebola patients, according to the BBC.
The searches are part of the so-called Western Area Surge, which aims to get Ebola patients into treatment and also to raise the number of available beds in the capital, the WHO said.

In Guinea, there has been no evident pattern in recent weeks, with the number of new confirmed cases each week fluctuating between 75 and 148. For the week ending Dec. 14, there were 76.
In Liberia, on the other hand, incidence is falling, with only six districts reporting new confirmed or probable cases in the week ending Dec. 14, although data are missing for much of the week.
The cumulative Ebola toll worldwide, to Dec. 14, is 18,603 confirmed, probable, and suspected cases in five affected countries (Guinea, Liberia, Mali, Sierra Leone, and the U.S.) and three previously affected countries (Nigeria, Senegal, and Spain), the agency said.

The U.S. has not had a new Ebola case since Craig Spencer, MD, was reported to be be cured Nov. 9; the country can be declared free of the disease Sunday, which will be 42 days after Spencer tested negative.
Mali also appears to have controlled the disease; all of the contacts of the country's eight confirmed and probable Ebola patients (six of whom died) have now passed the 21-day incubation period without developing the disease.


The last patient tested negative for the disease Dec. 6.

The WHO also reported, for the first time, population-based Ebola rates for Guinea, Liberia, and Sierra Leone:

In Guinea, there have been 22 reported cases and 14 deaths per 100,000 people, with a cumulative total of 2,416 cases and 1,525 fatalities.

Liberia has had 197 reported cases and 83 deaths per 100,000 population, with a total of 7,790 cases and 3,290 deaths.

And Sierra Leone has had 145 cases and 36 deaths per 100,000 people, for a total of 8,356 cases and 2085 deaths.

Meanwhile, researchers are reporting that laboratory tests show that 53 existing and approved drugs have the effect of blocking ebolavirus entry to target cells.

The list includes a wide range of drug classes: microtubule inhibitors, estrogen receptor modulators, antihistamines, antipsychotics, pump/channel antagonists, anticancer drugs, and antibiotics, according to Adolfo Garcia-Sastre, PhD, of the Icahn School of Medicine at Mount Sinai Hospital in New York City, and colleagues.
But more experiments will be needed to understand how useful any of the compounds might be, Garcia-Sastre and colleagues cautioned in Emerging Microbes and Infections.

The work is a positive step, commented Ben Neuman, PhD, of England's University of Reading, who was not part of the study.
The research "extends the list of drugs that are safe to use in people, and have been shown to interfere with Ebola in the lab," he said. But, he added, "it takes a lot to stop Ebola and none of the drugs identified in this study has been shown to protect an experimental animal yet."

"We now have a longer list of things that might work, but the list of things that definitely will work still unfortunately stands at zero," Neuman said.
Indeed, there is little evidence of efficacy even for the drugs that have been used experimentally during this current outbreak, according to the European Medicines Agency, which is conducting a continuing review of them.

The agency is looking at such medicines as brincidofovir, favipiravir, TKM-100802, and ZMapp -- all used to treat one or more patients -- but there is nothing to be said so far about their efficacy, according to an interim report.
"Treatments for patients infected with the Ebola virus are still in early stages of development," an agency spokesman said in a statement. "We encourage developers to generate more information on the use of these medicines in the treatment of Ebola patients."

Ebola: Poorer Economies Lose Out

Medic-ALL (23:11:2014) by Kayode Kuku

Having devoted a good percentage of posts on this blog to news on the ravaging impact of the Ebola virus epidemic over the last couple of months, the varying degrees of successes achieved in containing the deadly disease in different parts of the world seems to point indispuatably but not entirely to the inequality in healthcare systems.

Now we know that Ebola had been in existence as early as nearly 4 decades ago, with outbreaks in Sudan and Zaire occurring between June and November 1976. But asides from laymen hearing of "Ebola" in some Hollywood movies or medical students reading a few lines about the disease in their medicine notes, not even the March 2014 outbreak in Guinea  reported by the World Health Organization attracted any real attention either from the media or the World's biggest economies. It can easily be inferred by the closest observers that Ebola in Africa was not taken seriously until it entered into the commercial capital of one of Africa's biggest economies and one of the World's Biggest crude oil producing countries in Nigeria.

About a week following the entry of the Ebola-infected Liberian into Nigeria in July 2014, The WHO On 8 August 2014, the declared the epidemic to be an international public health emergency. Urging the world to offer aid to the affected regions, the Director-General said, "Countries affected to date simply do not have the capacity to manage an outbreak of this size and complexity on their own. I urge the international community to provide this support on the most urgent basis possible. This was after about 4 months of the disease ravaging the West African countries of Guinea, Sierra Leone and Liberia with death toll rising, about 1000 as at early August.


The truth is that the disease which is said to have entered into West Africa in December 2013, had unfortunately hit , "3 of Africa's Poorest economies" (to borrow the CNBC Africa headline from September 2014). The reality of this is that Ebola choose countries whose contributions to the Global Gross Domestic Product could easily be considered negligible by most. In a blog post in August "The Economics of Ebola",
The Liberian Finance Minister, cited the international aid of $200 million recieved via the specially set-up Ebola Fund established by the World Health Organization and World Bank in August to provide support for the 3 West African Countries. The question is how much attention would the the deadly disease have received if the countries affected were some of the region's biggest economies.

The disease however continues to have huge economic impacts even in this so-called poor economies with Ebola itself directly costing the governments of these countries increasingly. The factors  contributing to the growing cost of Ebola include direct costs of the illness (government spending on health care) and indirect costs, such as lower labor productivity as a result of workers being ill, dying or caring for the sick.

But the majority of the costs stem from the higher costs of doing business within countries or across borders. These are largely due to “aversion behavior”, or changes in the behavior of individuals due to fear of contracting the disease, which has also left many businesses without workers, disrupted transportation and led to restrictions on travel for citizens from the afflicted countries.

According to the latest World Bank group report, if the Ebola epidemic is contained by the end of 2014, the economic impacts on West Africa, including on Guinea, Liberia and Sierra Leone, could be lessened and economies would begin to recover and catch up quickly. If the crisis continues into 2015 as predicted, slower growth could cost the region $32.6 billion over 2014 and 2015 and lead to much higher levels of poverty.

There is no doubt that the inadequacies of the health-care systems in the three most-affected countries help to explain how the Ebola outbreak got this far. Spain spends over $3,000 per person at purchasing-power parity on health care; for Sierra Leone, the figure is just under $300. The United States has 245 doctors per 100,000 people; Guinea has ten. The particular vulnerability of health-care workers to Ebola is therefore doubly tragic: as of November 18th there had been 588 cases among medical staff in the three west African countries, and 337 deaths. The hope for these countries therefore lies in the hands of some of the world's bigger economies (who may not necessarily benefit in anyway from the epidemic stricken countries) to help their healthcare sysytem and invariably the "receeding" economy.

Sadly, Doctor loses Ebola Battle, Dies in Omaha

Medic-ALL (17:11:2014) Courtesy New York Times 

WASHINGTON — This time, the challenge of Ebola was much steeper for the doctors and nurses at Nebraska Medical Center, one of a handful of hospitals specially designated to handle cases of the deadly virus in the United States.

Unlike the two Ebola patients they had successfully treated earlier this year at the hospital’s biocontainment unit in Omaha, the man who arrived from Sierra Leoneon Saturday, Dr. Martin Salia, was in extremely critical condition. Dr. Salia, a legal permanent resident of the United States who had been working as a surgeon in Sierra Leone, died early Monday morning, barely into his second day of treatment, but almost two weeks into his illness.

The Late Dr Martin Saila

“Even the most modern techniques that we have at our disposal are not enough to help these patients once they reach a critical threshold,” said Dr. Jeffrey P. Gold, chancellor of the University of the Nebraska Medical Center, the hospital’s academic partner.

Dr. Philip Smith, the medical director of the biocontainment unit, said that Dr. Salia, 44, had initially been tested for Ebola in Freetown, the capital of Sierra Leone, on Nov. 7, but that the test came back negative. He was retested there on Nov. 10, at which point the results were positive. Dr. Smith said such false negatives were not uncommon early in the illness.

Dr. Daniel W. Johnson, a critical care specialist at Nebraska Medical Center, said that Dr. Salia’s kidneys had stopped functioning and that he was laboring to breathe when he arrived at the hospital late Saturday afternoon after a 15-hour flight. Doctors quickly tried two treatments they had used on their other Ebola patients: an experimental antiviral drug and a plasma transfusion from theblood of an Ebola survivor, which researchers believe may provideantibodies against the virus.

But Dr. Salia was already so ill that within hours of his arrival at the hospital, he needed continuous dialysis to replace his kidney function. By the pre-dawn hours of Sunday, he was in respiratory failure and needed a ventilator, Dr. Johnson said on Monday. Around the same time, he added, Dr. Salia’s blood pressure plummeted.

“He progressed to the point of cardiac arrest, and we weren’t able to get him through this,” Dr. Johnson said at a news conference in Omaha. “We really, really gave it everything we could.”

Dr. Smith said he did not know how Dr. Salia had contracted the virus. “He worked in an area where there was a lot of Ebola disease, much of it probably unrecognized,” Dr. Smith said, “and there were many opportunities for him to have contracted it.”

In the frenetic neighborhood of Kissy, on the eastern end of Freetown, an eerie quiet hung over the United Methodist Hospital on Monday as news spread that Dr. Salia had died. He was the chief medical officer and the only surgeon at United Methodist Kissy Hospital, according to United Methodist News Service.

Leonard Gbloh, the administrator of the hospital, said he did not think Dr. Salia could have contracted Ebola there.

“We have not been taking Ebola patients here” he said. “And we had stringent control measures in place to prevent it entering.”

The hospital even stopped all surgical work several months ago as a precaution, Mr. Gbloh said. Now, the hospital is being decontaminated and several staff members who came into contact with Dr. Salia after he fell ill are in quarantine there.

Victory over Ebola-Like Virus in Uganda!

Medic-ALL (14:11:2014)

In what can be regarded as another "win" for humans over the recently "more popular" viral haemorragic diseases, authorities in the east African country of Uganda reported that the country was now free of Marburg, a virus similar to Ebola in many respects, after no new cases had been reported for more than a month after a hospital worker died of the disease in the capital, Kampala. The declaration by the United Nations Health Agency comes after a 42-day Surveillance period.

The virus is transmitted through bodily fluids or by handling infected wild animals, Marburg starts with a severe headache followed by hemorrhaging and kills in 80 percent or more cases within about a week. There is no vaccine or specific treatment for the virus.

A total of 197 people were in contact with the healthcare worker, but none of them were found to have been infected, Junior health minister Sarah Opendi told a news conference.

Opendi said 42 days was the minimum period of monitoring before an outbreak is declared contained, and there had been no new cases reported since the death in Kampala on Sept. 28.

"This implies that the Marburg outbreak in the country has been completely controlled," she said.

The worst outbreak of Ebola on record has killed nearly 5,000 people - all but a handful in West Africa's Guinea, Liberia and Sierra Leone - since March.

Marburg disease virus (MVD) (formerly known as Marburg haemorrahagic fever) was first identified in the 1967 epidemics in Marburg (hence the name) and Frankfurt in Germany and Belgrade in the former Yugoslavia following importation of infected monkeys from Uganda.

Uganda, according to the Health Minister of the country, in 2012, endured an outbreak of Marburg that killed 9 of the 18 people infected

U.S free of Ebola case as New York Doctor is Cleared!

Washington Post (10:11:2014) by Mark Berman

The doctor who contracted Ebola in West Africa before returning to New York City has been declared free of the virus, hospital officials announced Monday. This news means that 41 days after the first Ebola diagnosis in the United States, there are no known cases of the virus in the country.

Craig Spencer, 33, who had been treating Ebola patients in Guinea, was diagnosed with Ebola on Oct. 23. Bellevue Hospital Center in New York City, where Spencer was being treated, confirmed in a statement Monday that he “has been declared free of the virus.” Spencer will be discharged on Tuesday, according to the hospital. (News of his release was first reported Monday by theNew York Times.)

Spencer’s diagnosis created concerns in New York, as the news of his illness was followed by the revelation that he visited a popular restaurant and coffee shop, rode multiple subway lines and went to a bowling alley and bar in Brooklyn. As city officials preached caution and calm,“disease detectives” fanned out to visit the places Spencer had gone and visit the people with whom he had interacted.

After returning to New York, Spencer had been self-monitoring and taking his temperature. He reported a fever of 100.3 degrees on Oct. 23, two days after he began feeling sluggish, and was taken to the hospital and isolated. He was the fourth person diagnosed with Ebola in the United States and the only one of this group to contract the disease after treating patients overseas. (Other people responding to the epidemic in West Africa have been diagnosed and brought back to the country for treatment.)

His diagnosis also sparked a panic among authorities, as the governors of New York and New Jersey hurriedly announced that they would quarantine any medical workers returning from West Africa, a highly-criticized move that went against the advice of public-health officials. This drama spilled up the East Coast, as a nurse who had treated patients in West Africa (and had no symptoms of Ebola) was quarantined in New Jersey and had a prolonged confrontation with authorities in Maine over her treatment.

The first person diagnosed in this country, Thomas Duncan, was a Liberian man who contracted it before flying to Texas in September; two nurses who treated Duncan were infected during his hospitalization. Duncan died eight days after he was diagnosed, becoming the only person to die from Ebola in the United States, while the Texas nurses who contracted Ebola were both treated and declared safe. The news that Spencer was cleared came three days after the last person being monitored for Ebola in Texas was also cleared, ending the Ebola saga there.

More than 350 people were being actively monitored by the New York City health department for Ebola as of last week, the department said in a statement. Most of these people had traveled to New York City from Liberia, Guinea or the Sierra Leone, but that number also included Bellevue staff members treating Spencer and lab workers who took his blood.

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said Monday that people should be reassured by the fact that tried-and-true approaches, such as contact-tracing and active monitoring, have helped to prevent broader transmission of the disease in the United States.

“In fact, it has worked,” he said, noting that contacts of patients in Dallas have all been cleared and that people who interacted with Spencer so far appear healthy.

“That doesn’t mean we are not going to see another case; it’s possible we will,” he said. “[But] I think we are pretty well prepared.”

New York Doctor with Ebola after return from Guinea

By Ellen Wulfhorst and Sebastian Malo

NEW YORK (Reuters) - A doctor who worked in West Africa with Ebola patients was in an isolation unit in New York on Friday after testing positive for the deadly virus, becoming the fourth person diagnosed with the disease in the United States and the first in its largest city.

The worst Ebola outbreak on record has killed at least 4,900 people and perhaps as many as 15,000, mostly in Liberia, Sierra Leone and Guinea, according to World Health Organization figures.

Only four Ebola cases have been diagnosed so far in the United States: Thomas Eric Duncan, who died on Oct. 8 at Texas Health Presbyterian Hospital in Dallas, two nurses who treated him there and the latest case, Dr. Craig Spencer.

Spencer, 33, who worked for Doctors Without Borders, was taken to Bellevue Hospital on Thursday, six days after returning from Guinea, renewing public jitters about transmission of the disease in the United States and rattling financial markets.

Three people who had close contact with Spencer were quarantined for observation - one of them, his fiancée, at the same hospital - but all were still healthy, officials said.

Mayor Bill de Blasio and Governor Andrew Cuomo sought to reassure New Yorkers they were safe, even though Spencer had ridden subways, taken a taxi and visited a bowling alley between his return from Guinea and the onset of his symptoms.

"There is no reason for New Yorkers to be alarmed," de Blasio said at a news conference at Bellevue. "Being on the same subway car or living near someone with Ebola does not in itself put someone at risk."

Health officials emphasized that the virus is not airborne but is spread only through direct contact with bodily fluids from an infected person who is showing symptoms.

After taking his own temperature twice daily since his return, Spencer reported running a fever and experiencing gastrointestinal symptoms for the first time early on Thursday. He was then taken from his Manhattan apartment to Bellevue by a special team wearing protective gear, city officials said.

He was not feeling sick and would not have been contagious before Thursday morning, city Health Commissioner Mary Travis Bassett said.

Owners of the bowling alley he visited said they had voluntarily closed the establishment for the day as a precaution. But the driver of the ride-sharing taxi Spencer took was not considered to be at risk, and officials insisted the three subway lines he rode before falling ill remained safe.

"We consider that it is extremely unlikely, the probability being close to nil, that there would be any problem related to his taking the subway system," Bassett said.

The U.S. Centers for Disease Control and Prevention (CDC) will confirm Spencer's test results within 24 hours, she said.

RESIDENTS, INVESTORS RATTLED

His case brings to nine the total number of people treated for the disease in U.S. hospitals since August, but just two - Duncan's nurses - contracted the virus in the United States.

The New York case surfaced days after dozens of people who were exposed to Duncan emerged from the 21-day incubation period with clean bills of health, easing a national sense of crisis that took hold when his nurses, Nina Pham and Amber Vinson, became infected.

"I'm really concerned," said Kiki Howard, 26, a student who lives on the block next to Spencer's home in Harlem. "There's a school at the end of the block. My main concern is for the safety of the children."

The health commissioner said Spencer's apartment was isolated and sealed off, noting, "I see no reason for the tenants in the apartment building to be concerned."

Still, there were signs that the latest Ebola case had unnerved investors. S&P futures fell 9 points or 0.45 percent. The dollar slipped against the euro and the U.S. 10-year Treasury rose, lowering its yield to about 2.24 percent.

The city health commissioner said Spencer completed work in Guinea on Oct. 12 and arrived at John F. Kennedy International Airport in New York on Oct. 17. His Facebook page, which included a photo of him clad in protective gear, said he stopped over in Brussels.

Spencer has specialized in international emergency medicine at Columbia University-New York Presbyterian Hospital in New York City since 2011.

Columbia, in a statement, said he has not been to work nor seen any patients since his return.

A woman named Morgan Dixon was identified on Spencer’s Facebook page as his fiancée. Her Linked-In profile said she worked in nonprofit management and international development with the Hope Program, a career development agency for homeless and welfare-dependent adults.

The CDC did not name Spencer but said he "participated in the enhanced screening" instituted for all travelers returning from Guinea, Liberia and Sierra Leone this month at five major U.S. airports - including Kennedy.

The doctor "went through multiple layers of screening and did not have a fever or other symptoms of illness", the CDC said in a statement.

Nigeria Declared Ebola-Free by WHO

Medic-ALL (20:10:2014) by Kayode Kuku

With no new cases of Ebola reported in Nigeria over the last 42 days, the World Health Organization (WHO) today declared the country "Ebola Free", a sign of how the deadly virus could have been easily contained had the other West African countries ravaged by the disease acted swiftly.

There haven’t been any cases of Ebola in 42 days, said WHO Country Representative Rui Gama Vaz in a news conference in Abuja, Nigeria’s capital.

“The last chain of transmission has been broken. The disease is gone,” said Dr. Vaz. “This is a spectacular story, that Ebola can be defeated.”

This is following an announcement that Senegal is also rid of the virus.

The entire world and health officials particularly were concerned of a possible worldwide outbreak  and wary of the spread throughout the world when a Liberian-American "transported" the virus into Nigeria when he flew into Lagos, the Country's most populous city with a population of about 21 million people late July.

A different story has been unfolding in Liberia, Sierra Leone, and Guinea, whose governments didn’t notice Ebola had arrived in their interiors until March, four months after the disease first erupted in rural Guinea late last year.

More than 4,500 people are known to have died from the disease in those countries, the WHO says. Thousands more are thought to have contracted it without ever being tallied in the United Nations health agency’s records.

Meanwhile the United States continue to put in place measures to ensure the diseses which has so far been confirmed in 3 persons in the U.S. 43 contacts of the country's first Ebola case, Thomas Eric Duncan have been cleared after not developing any symptoms following a 21-day period in quarantine, while 4 others are close to the end of the isolation period.

 Reports from Spain, reveal that the nurse's aide has also beaten Ebola after spending weeks hospitalized with the disease.

End of 21-day Quarantine for Family of Ebola Patient

USA Today News (20:10:2014)

People who had contact with Ebola patient Thomas Eric Duncan before he was hospitalized are breathing a sigh of relief today.

Those 48 contacts, including four family members who shared a small Dallas apartment with him, have completed the 21-day observation period without falling ill and are no longer at risk of the disease. About 10 of the 48 contacts were considered to be a higher risk because of their closer contact with Duncan.

Ebola has an incubation period of up to 21 days, according to the World Health Organization. People who are exposed to an Ebola patient who don't become sick during that time are considered to be out of the woods.

That's welcome news to Dallas and U.S. public health officials, who have struggled to contain Ebola since Duncan's diagnosis at Texas Health Presbyterian on Sept. 28. Duncan died Oct. 8.

Last week, two of Duncan's nurses were diagnosed with Ebola and have been moved to specialized hospitals. Other health workers who treated Duncan during his hospital stay continue to monitor themselves for fever and other symptoms.

In Spain, a nursing assistant appears to have recovered from the Ebola virus, the Associated Press reported Sunday.

The good news for Duncan's family should also reassure Americans about a fact that public health officials have been emphasizing for weeks -- that Ebola is not spread through casual contact -- said Robert Murphy, director of the Center for Global Health at Northwestern University Feinberg School of Medicine.

Dallas Health officials quarantined 4 members of Duncan's family after he was diagnose, ordering them not to leave the small apartment they shared with Duncan. Officials worried that the family was at risk

not just because they spent time with Duncan while he was sick but also because they stayed in an apartment with his soiled bed linens after he was hospitalized.

The fact that Duncan's family remained healthy even as two of his nurses became infected illustrates the peculiar nature of Ebola, said Peter Hotez, dean of the National School of Tropical Medicine and professor at Baylor College of Medicine in Houston.

Although the West Africa outbreak of Ebola has a 70% mortality rate, the virus is actually not very contagious in the early stages of disease when people are most likely to circulate in the community, Hotez said. Ebola doesn't spread through coughs and sneezes, only through direct contact with bodily fluids.

Even then, people aren't contagious at all until they begin showing symptoms such as a fever. Before symptoms appear, levels of the virus in their blood are too low to be measured, Hotez said.

Yet Ebola is frighteningly infectious at advanced stages of the disease, when the virus begins multiplying out of control and patients begin producing large amounts of diarrhea, vomit and blood. At that point, even a tiny amount of blood is teeming with Ebola, which puts nurses and caregivers at high risk, Hotez said.

Few people in the general community are exposed to Ebola patients who are that contagious, because patients at that stage are usually too sick to move around. Most are hospitalized if a bed is available. In West Africa, patients who can't get to a hospital are bedridden and typically attended by relatives.

Those aspects of Ebola help explain why, on average, people in West Africa spread the disease to only one or two other people, said Paul Offit, chief of infectious diseases at Children's Hospital of Philadelphia. In contrast, people with an airborne virus such as measles can spread the disease to 14 susceptible people.

Ebola has spread in West Africa because of burial rites that aren't practiced in the USA, in which relatives of the deceased touch the body and prepare it for the grave.

Only about 15% of Ebola cases in West Africa involve children, reflecting the fact that children are rarely home caregivers, Offit said.
