Ebola infections with no symptoms are possible. And they could help fight the West Africa epidemic.

http://www.washingtonpost.com/news/...they-could-help-end-the-west-africa-epidemic/

Thomas Eric Duncan had chills and a fever and was using the bathroom often on Sept. 28. They were all symptoms of the Ebola virus that Duncan was eventually diagnosed with at Texas Presbyterian Hospital.

At the time, however, he was staying in a small, two-bedroom apartment in Dallas with four other people.

In the process of cleaning that apartment after Duncan was hospitalized, Dallas officials said that there were three mattresses in the home. And family members reported that Duncan, who died Oct. 8, had contact with all of them.

Yet two-thirds of the way through their quarantine period, all of the people who were living in that apartment -- Duncan's fiancee Louise Troh; her 13-year-old son; Duncan's nephew; and another man -- have shown no symptoms of the Ebola virus. And at this stage in the incubation period, they are unlikely to, Centers for Disease Control and Prevention director Tom Frieden said.

Had to chuckle at that last line. When did he ever say anything that was true about this?

They have a ways to go yet if you go by the new WHO guidelines that say it takes 42 days now.

And yeah, Frieden is a joke. An embarrassment to the CDC and the US.

So, wait, she is the MOST likely person in the universe to have contracted Ebola from Duncan, but they're just looking for "symptoms"? Are they not testing??

The end times are here.
The title of the OP and the content of the article didn't quite make sense, so I went to the link and found more information that helps to reconcile the title and the article. Here is the entire article:


Thomas Eric Duncan had chills and a fever and was using the bathroom often on Sept. 28. They were all symptoms of the Ebola virus that Duncan was eventually diagnosed with at Texas Presbyterian Hospital.

At the time, however, he was staying in a small, two-bedroom apartment in Dallas with four other people.

In the process of cleaning that apartment after Duncan was hospitalized, Dallas officials said that there were three mattresses in the home. And family members reported that Duncan, who died Oct. 8, had contact with all of them.

Yet two-thirds of the way through their quarantine period, all of the people who were living in that apartment -- Duncan's fiancee Louise Troh; her 13-year-old son; Duncan's nephew; and another man -- have shown no symptoms of the Ebola virus. And at this stage in the incubation period, they are unlikely to, Centers for Disease Control and Prevention director Tom Frieden said.

So how could all the people who spent days in close quarters with a man sickened with Ebola manage to evade illness?

One possible explanation that has rarely been discussed is that people could be infected with Ebola without ever showing symptoms. The phenomenon is called "asymptomatic infection," and it is an unusual but potentially very real feature of the Ebola virus in humans.

"Asymptomatic cases are likely to have a little bit of virus for a little bit of time then fight it off," said Steve Bellan, a post-doctoral researcher at the University of Texas at Austin.

Asymptomatic individuals aren't contagious, as Ebola is only transmitted through direct contact with bodily fluids of an infected and symptomatic person. Studies conducted in previous outbreaks have found that between 20 and 60 percent of people in a population can exhibit signs of asymptomatic infection, Bellan said.

These people can come in close contact with the virus and show an immune response in blood tests, but they do not experience typical Ebola symptoms such as fever, diarrhea or vomiting. The virus never progresses to its extreme -- and often deadly -- lengths.

No one knows yet whether people with asymptomatic infections are immune to the virus in some or all cases. But if they are, those people could be recruited to help fight the Ebola epidemic by treating patients.

And the blood of asymptomatic individuals, if they are also immune to the virus, could potentially be used in transfusions to help care for sick patients.

"It's not known whether they have protective immunity," said Bellan. "There's substantial evidence that suggests that there are a lot of people out there who have been asymptomatically infected, and understanding whether they have protective immunity could be very useful."

So far, there has been little or no mention of this phenomenon, because until now, Ebola infections have been relatively rare. Bellan and several other researchers who co-wrote a correspondence published in the Lancet journal this week want to change that by calling for additional research on the subject.

In Bellan's modeling of the current epidemic, his team found evidence that the effect of having a population of people who do not show symptoms even when they are exposed to the disease will start to show over time in Ebola-affected West African countries.

"At the beginning, it doesn't matter," he said. "But eventually what ends up happening is that you get an accumulation of people who are immunized by getting infected but never get sick, that helps bring the infected population down."

However, with the crisis raging in Liberia, Guinea and Sierra Leone with resources still limited, it isn't feasible to test people for Ebola unless they show symptoms. Already, many of whom are treated for the virus or die, can't be tested because of limited laboratory capabilities.

But Bellan said that any vaccine or treatment trial on the ground in West Africa might be the best -- and only -- opportunity to study asymptomatic infections.

"The greatest potential lies in any other studies that might be done with regard to vaccines or transfusions or any targeted interventions to help out people at high risk of contracting the virus," Bellan said. "If you did do a study where you randomly assigned half the people to get vaccinated and the other half do not, in the population that doesn't get vaccinated, you can identify people who didn't get vaccinated but have been asymptomatically infected."

In Dallas, all 48 people who had contact with Duncan after he became ill but before he was hospitalized are still asymptomatic. Bellan believes that researchers in the United States can begin to look at least part of this puzzle there as well.

"In the Dallas case, you can start to get at this symptomatic proportion but you could not figure out whether it's protective," Bellan said.

DREXEL STUDY QUESTIONS 21-DAY QUARANTINE PERIOD FOR EBOLA

October 15, 2014
Ebola in Uganda
Quarantining individuals who might have been exposed to Ebola for a period of 21 days has been a standard procedure recommended by the Centers for Disease Control and Prevention, but it might not be long enough.

As medical personnel and public health officials are responding to the first reported cases of Ebola Virus in the United States, many of the safety and treatment procedures for treating the virus and preventing its spread are being reexamined. One of the tenets for minimizing the risk of spreading the disease has been a 21-day quarantine period for individuals who might have been exposed to the virus. But a new study by Charles Haas, PhD, a professor in Drexel’s College of Engineering, suggests that 21 days might not be enough to completely prevent spread of the virus.

Haas’s study “On the Quarantine Period for Ebola Virus,” recently published in PLOS Currents: Outbreaks looks at the murky basis for our knowledge about the virus, namely previous outbreaks in Africa in 1976 (Zaire) and 2000 (Uganda) as well as the first 9 months of the current outbreak.

In both cases, data gathered by the World Health Organization reported a 2-21 day incubation period for the virus –meaning that after 21 days if the individual hasn’t presented symptoms they are likely not to be infected or contagious. This is likely the genesis of the Centers for Disease Control and Prevention’s 21-day quarantine period, but there is little indication from the CDC as to what other considerations played into this policy.

“Twenty-one days has been regarded as the appropriate quarantine period for holding individuals potentially exposed to Ebola Virus to reduce risk of contagion, but there does not appear to be a systemic discussion of the basis for this period,” said Haas, who is the head of the Civil, Architectural and Environmental Engineering Department at Drexel.

Haas suggests that a broader look at risk factors and costs and benefits should be considered when setting this standard. With any scientific data of this nature there is a standard deviation in results –a percentage by which they may vary. In the case of Ebola’s incubation period the range of results generated from the Zaire and Uganda data varied little. This might have contributed to the health organizations’ certainty that a 21-day quarantine period was a safe course of action.

But looking more broadly at data from other Ebola outbreaks, in Congo in 1995 and recent reports from the outbreak in West Africa, the range of deviation is between 0.1 and 12 percent, according to Haas. This means that there could be up to a 12 percent chance that someone could be infected even after the 21-day quarantine.

“While the 21-day quarantine value, currently used, may have arisen from reasonable interpretation of early outbreak data, this work suggests reconsideration is in order and that 21 days might not be sufficiently protective of public health,” Haas said.

Haas, who has extensive background in analyzing risk of transmitting biological pathogens, explains that these quarantine periods must be determined by looking at the cost of enforcing the quarantine versus the cost of releasing exposed individuals. Looking at the potential tradeoff between costs and benefits as the quarantine time is extended should guide public health officials in determining the appropriate time. Obviously, with more contagious and potentially deadly diseases the cost of making a mistake on the short side when determining a quarantine is extremely high.

“Clearly for pathogens that have a high degree of transmissibility and/or a high degree of severity, the quarantine time should be greater than for agents with lower transmissibility and/or severity. The purpose of this paper is not to estimate where the balancing point should be, but to suggest a method for determining the balancing point.”

Now THAT'S a classic intelligence op - "Ebola infections with no symptoms are possible."

So, one can have The Big E and not be affected by it? No runny nose, no itches, no blotches, nothing? Really? The dread 'disease' has no effect?

Why that means, well, yes, EVERYONE must have it! Yeah, that's right - we ALL have it and therefore we ALL have to get the vaccine.

Barnum was right - there is a sucker born every minute. Geesh.

Sorry I did not post the whole article correctly. I got a warning about it. It sounds like they are not going to test anybody without symptoms, but yet the girlfriend could have Ebola and I found this article. - Ebola victims without symptoms can still be contagious

NEW YORK – A group of German medical doctors in a peer-reviewed medical journal article published by Oxford University Press have challenged a key assumption regarding the Ebola virus repeatedly asserted by Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention in Atlanta.

The researchers found that a patient showing no symptoms of the disease can still transmit a virus like Ebola by air if droplets containing the virus are transmitted to another person by a sneeze or cough.

As WND reported Tuesday, the World Health Organization has admitted that “wet and bigger droplets from a heavily infected individual, who has respiratory symptoms caused by other conditions or who vomits violently could transmit the Ebola virus over a short distance to another nearby person.”

WHO said it could happen when “virus-laden heavy droplets are directly propelled, by coughing or sneezing onto the mucus membranes or skin with cuts or abrasions of another person.”

Still, WHO added a qualification, insisting the transmission of Ebola by sneezing or coughing is not within its definition of airborne transmission.

News broke Wednesday morning that the first person diagnosed with Ebola in the U.S., Thomas Eric Duncan, had died in Dallas. The victim’s home neighborhood in the Liberian capital, meanwhile, remained under quarantine.

Later Wednesday, a Texas sheriff’s deputy was rushed to the hospital in Frisco, Texas, with Ebola symptoms after delivering a quarantine notice to the apartment where Duncan was staying.

WND reported Wednesday Liberia is preventing journalists from reporting Ebola-related stories from health care centers in the country unless they obtain written permission from the government. The news came as the World Health Organization issued a statement warning that the officially reported decline in new cases in Liberia over the past three weeks “is unlikely to be genuine,” because problems with data gathering continue.

What do YOU think? What is your reaction to death of Dallas Ebola victim? Sound off in today’s WND poll

‘Not easily detected’

The German physicians, led by Dr. Timm H. Westhoff of the Department of Nephrology at the Carité Campus Benjamin Franklin in Berlin, noted in a virology blog published Feb. 12, 2009, that acute viral infections such as Ebola hemorrhagic fever may cause little or no clinical symptoms in a so-called “inapparent infection” yet may be contagious.

“A well-known example is poliovirus: over 90% are without infections,” Westhoff and his colleagues continued. “During an inapparent infection, sufficient virus replication occurs in the host to induce antiviral antibodies, but not enough to cause disease. Such infections are important for the spread of infection, because they are not easily detected.”

Westhoff and his colleagues then made the key point that individuals with an inapparent infection, showing no symptoms, can yet spread diseases such as polio.

“During the height of the polio epidemic in the United States, the quarantine of paralyzed patients had no effect on the spread of the disease, because 99 percent of the infected individuals had no symptoms and were leading normal lives spreading infection.”

Westhoff and his colleagues also discussed the risk of spreading Ebola by sneezing or coughing.

“An example of a classic acute infection is uncomplicated influenza,” the medical doctors noted. “Virus particles are inhaled in droplets produced by sneezing or coughing, and begin replicating in ciliated columnar epithelial cells of the respiratory tract. As new infectious virions are produced, they spread to neighboring cells.”

The point was clear: “Inapparent infections probably are important features of pathogens that are well-adapted to their hosts. They replicate sufficiently to endure the spread to new hosts, but not enough to damage the host and prevent transmission.”

Westhoff and his associates conclude: “Acute viral infections are responsible for epidemics of disease involving millions of individuals each year, such as influenza and measles. When vaccines are not available, acute infections are difficult to control – most are complete by the time the patient feels ill, and the virus has already spread to another host.”

The German physicians published in 2008 the fundamental medical research that formed the basis for their blog comments, demonstrating kidney-transplant patients could carry the norovirus infection that is common in cases of acute gastroenteritis, even if the patient was asymptomatic.

Westhoff’s 2008 study provided “the first evidence” that norovirus, typically a self-limiting disease of short duration, can cause chronic infection in renal transplant recipients,” even when there are no symptoms of acute gastroenteritis evident in the patient.

Dr. Norman M. Balog, D.O., a board-certified family doctor practicing in Silver Spring, Maryland, brought the research of the German medical team to the attention of WND as evidence that the CDC’s Frieden could not prove his assertion air travel was safe as long as a person infected with Ebola were not showing symptoms. An infected person can go as long as 21 days in an incubation period before being infected.

“Dr. Freiden is either completely uninformed of this research,” Balog explained to WND in an exclusive telephone interview, “or he is deliberately lying because he does not want to panic the general public.”

Balog pointed out that asymptomatic carriers of diseases infecting others is a phenomenon that has been widely documented in virology studies for decades.

“There’s a good potential that on any given day a person you may shake hands with will have Strep Group A Streptococcus that causes sore throats,” he pointed out. “Shaking hands you take the risk you are going to get the Streptococcus virus, even if the person you shook hands with looked perfectly well.”

Balog explained to WND much of the fundamental research on Ebola, including the conditions under which asymptomatic carriers of the disease can infect others, has yet to be conducted and reported in peer-reviewed medical journals.

“Dr. Freiden and the CDC have been reassuring the American public from the beginning of the current outbreak that we can contain and control Ebola, no problem; but the first assurances were three continents ago,” he pointed out. “Now we have Ebola in the United States and in Spain. Where is Ebola going to show up next?”

Balog was critical of the steps taken so far by the CDC to contain the Ebola outbreak.

“Ebola is spreading a lot faster than anybody expected,” he said.

“But even today we are not stopping people from West Africa from boarding international air flights; health officials in Dallas did not put up a fence around Duncan’s apartment complex; and it took several days before Dallas health authorities found anyone qualified to clean up the vomit outside Duncan’s apartment. And then the workers just washed the vomit down into the town storm drains.”

Balog pointed out the medical literature on virology commonly says asymptomatic but infected individuals can spread a disease to others before showing any signs of being sick.

“We have medical models that say a person is capable of secreting a virus like Ebola in bodily fluids before the person displays symptoms of the disease,” he stressed, “and that medical evidence is simply being ignored by Dr. Frieden and the CDC when the public is told repeatedly it’s OK to let Ebola-infected people fly as long as they don’t have a fever.”

last i heard louise and the otehrs are supposed to be released from quarantine this sunday, according to a lady spokesperson and they are trying to make plans what to do next. i was hoping they would keep them for the 42 days and also test their blood for just in case kinda thing. but i guess they wont test unless they have symptoms.

well, yes. actually, that is exactly what it means. every single disease is the same in the regard. in every disease, there is a certain portion of the population that does get the infection (they have the antibodies to prove it), but they do not exhibit the symptoms, or perhaps they may have a slight headache or very low grade fever, but not enough to alert them or anyone else that they are ill. they can be carriers. i used to know a person that was a carrier for strep. the kids and spouse would get strep throat, but they never showed any symptoms. every time one of them would get it, the doctor would have them all come in and be tested. they all had the bacteria, but that person never showed symptoms.

during the plague, not everyone got sick with symptoms, but they were around those that were. even people in their own homes died, but they never showed symptoms. in africa right now, there are many stories of people that lived with ebola patients in their home and the patient died there, and the person caring for them (with no protective equipment) didn't get sick.

being asymptomatic is not a part of a plot to fool people. it simply is a fact.
