    Ebola Exponential
AI Thread Summary
Ebola is currently experiencing exponential growth in new infections, raising concerns about containment efforts. With an estimated 125 new cases daily, many believe the actual numbers are underreported, particularly in West Africa. The outbreak remains largely confined to this region, but increased mobility poses risks of spreading to larger cities, which could exacerbate the situation. There is speculation that the outbreak could persist for years unless a vaccine or effective treatment is developed. Quarantine measures are seen as the best defense against further spread, especially if the virus reaches densely populated areas.

Mostly a catalog of failures in the system, which had been proclaimed as prepared.

The first blog also states;

Some of us suspect the Dallas patient was not admitted in part because he was uninsured. He was inexplicably and irrationally sent home with antibiotics for a presumed viral infection, even though he should have been considered an obvious risk.

I'm uncomfortable with the amount of confidence that the CDC and TV ebola experts have on the world's ability to contain this. My guess, is that this is a new strain and its characteristics are poorly understood. Also, the virus has been spreading among people for 11 months now, so it has had some time to evolve within human populations.

We don't know how efficiently it spreads, and we don't know how many carriers out there are asymptomatic. I have read that asymptomatic ebola hosts don't spread the disease. However, I suspect this was characteristic of previous ebola outbreaks and it has not yet been observed with this strain. Hopefully other countries will be able to repeat Nigeria's successful containment. SARS was airborne, and the world was able to contain it. On the other hand, ebola's incubation period is twice that of SARS, and the comparison is not entirely a valid one.
It has been proven that ebola is not an airborn virus. They are still trying to determine contagion, especially in light of the Dallas nurse's diagnosis. There is no need to speculate about a new strain, they are still figuring out the current and only one.

About 70 hospital staffers cared for Ebola patient
http://news.yahoo.com/70-hospital-staffers-cared-ebola-patient-224521642.html

U.S. needs to rethink Ebola infection controls, says CDC chief
http://news.yahoo.com/u-needs-rethink-ebola-infection-controls-says-cdc-005533255.htmlThe fact that Duncan was sent home with a 103 F fever is mind boggling. He was given antibiotics for an apparent viral infection, for which antibiotics would be ineffective. If the fever was related to a bacterial infection, then he should have been hospitalized on the spot.

Well, if it was viral, no antibiotics should have been prescribed. If it was bacterial, then tests should have been performed, but he had no insurance and a temp of 103F is not that uncommon or life threatening that would require them to treat him in an ER. A normal doctor's office or accute care clinic would have been correct. That it turned out to be ebola is what makes it newsworthy. The only time I was admitted to a hospital *with a temperature* was 105F and I became unconscious for 3 days, and I had insurance.

In this case, the screw up was his "history", that should have raised an immediate red flag.

Do animals get sick from ebola? How does first patient get infected?

The virus apparently resides in some animals (e.g., bats, . . . . ?) in the African wild. People capture those animals for food. People who eat contaminated 'bush meat' will contract the virus, and they can spread it to others.

The number of deaths due to Ebola now stands at 4447
http://news.yahoo.com/10-000-ebola-cases-per-week-could-seen-124410379.html
In Berlin, a U.N. medical worker infected with Ebola in Liberia died despite "intensive medical procedures." The St. Georg hospital in Leipzig said Tuesday that the 56-year-old man, whose name has not been released, died overnight of the infection.

The man tested positive for Ebola on Oct. 6, prompting Liberia's U.N. peacekeeping mission to place 41 other staff members under "close medical observation."

He arrived in Leipzig for treatment on Oct. 9. The hospital's chief executive, Dr. Iris Minde, said at the time there was no risk of infection for other people, since he was kept in a secure isolation ward specially equipped with negative pressure rooms that are hermetically sealed.

He was the third Ebola patient to be flown to Germany for treatment. The first man recovered and returned home to Senegal. A Uganda aid worker is still being treated in Frankfurt.

There are 5 species though:

Ebola virus disease (WHO)
Fact sheet N°103
Updated September 2014
The virus family Filoviridae includes 3 genera: Cuevavirus, Marburgvirus, and Ebolavirus. There are 5 species that have been identified: Zaire, Bundibugyo, Sudan, Reston and Taï Forest. The first 3, Bundibugyo ebolavirus, Zaire ebolavirus, and Sudan ebolavirus have been associated with large outbreaks in Africa. The virus causing the 2014 west African outbreak belongs to the Zaire species.

I just tallied up the mortality rate for 4 of the 5 species since the 1978 thru 2012. The Reston species is not listed.

Species ___ Mortality rate _ Total Cases
Bundibugyo _ 32.0% __________ 206
Sudan ______ 53.8% __________ 792
Taï Forest _100.0% ____________ 1
Zaire ______ 79.1% _________ 1388


Unfortunately, this is the Zaire species we are dealing with now.

And, we have apparently gone from under-precaution, to over-precaution:

Ebola fears: La. waste facility won't take Dallas man's incinerated belongings
October 13, 2014
NEW ORLEANS - A Louisiana waste disposal facility said Monday it would not accept the ash from the incineration of a Texas Ebola victim's belongings, at least not until state officials agree that doing so would pose no threat to the public.
...
Veolia officials did not return calls for comment Monday. CWM said it was informed by Veolia that the materials had been decontaminated before Veolia accepted them and burned them at 2,100 degrees Fahrenheit.
2,100°F is the melting point of Iron. (ref)
That would make it quite the hyperthermophile, if it could withstand that temperature.

Current record: 251°F for for Methanopyrus kandleri.

Feds could have done more in Dallas Ebola case, CDC director says
http://news.yahoo.com/feds-should-h...-ebola-case--cdc-director-says-214128692.html

From now on, Frieden said, the CDC will rush a team of infectious disease specialists to assist U.S. hospitals that confirm having a case of the deadly Ebola virus.

“We will put a team on the ground within hours with some of the world's leading experts in how to take care of and protect health care workers from Ebola infection,” Frieden said. “I wish we had put a team like this on the ground the day the first patient was diagnosed.”

In re Protocol. Radiation workers are regularly retrained and re-qualified on removal of Anti-C PPE. A violation of those protocols after working in highly contaminated areas is quite apparent on exit surveys or internal monitoring. A dress-out for a highly contaminated wet work area easily takes an hour (Anti-C's, double liquid impervious, air-fed/respirator) and a proper undress takes as long, longer with the surveys.

I have read medical attendants' ("nurses") comments complaining of the fifteen minutes for dress-out.

I did close-out inspection and certification of radioactive liquid holding tanks three times in my career. I also dried reactor vessel shield water (saturated K2CrO4) tanks for my experience in wet work.

Have people never played quarantine before? It's absolutely ridiculous staff that were working on Duncan were allowed to travel without a short period of quarantine in their own home. It's a matter of national security, now the CDC is looking for over 100+ more people who make have had contact with the 2nd nurse now infected with Ebola. One person can easily lie, get into this country, and spread Ebola. How many other people are we letting in every single day from Ebola hotspots? We also sent hundreds of troops to those areas that will be coming home soon, how many of them will return infected?

Apparently Ebola isn't as easily contained as we all thought it would be, even though we 'are a 1st world country with a reliable health care system'. Do we really need to unnecessarily push our entire health care system to a breaking point just to test it out?

To expand on your post.

The CDC said the nurse flew on Frontier Airlines Flight 1143 from Cleveland to Dallas/Fort Worth on Oct. 13. She first reported to the hospital with a low-grade fever on the morning of Oct. 14 and was immediately placed into an isolation unit.

Public Health workers will begin interviewing the 132 passengers on Flight 1143 immediately.

I think you might want to step back and take a deep breath. We should be more afraid of the common flu than Ebola. In addition, anytime we send our troops to foreign places, we have a risk of importing disease from the region. Finally, ebola is more of a risk to health care workers than airplane passengers. They have to deal directly in bodily fluids, and they must be rigorous about decontamination afterwards. These nurses need to work in pairs, and they need to follow checklists a lot. Some of these mistakes has been caused by the lack of checklists. For example, asking someone if they have traveled recently to Africa should probably be on the checklist.

Personally, I'm more afraid of the fear of Ebola than I am Ebola itself.

Flight 1143 was obviously a *return* flight for the nurse. What about the *outbound* flight to Cleveland? I assume CDC assumes no symptoms were apparent at that point, so Ebola was not contagious at that point?

They experts keep saying that Ebola is hard to catch but I have heard no expert even mentioned the following two things.

The virus can survive several hours in a dried state on doorknobs or countertops.

If the fluid remains wet and at room temperature it can survive for days outside the body.

Filoviruses have been reported capable to survive for weeks in blood and can also survive on contaminated surfaces, particularly at low temperatures (4°C)http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote52 http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote61. One study could not recover any Ebolavirus from experimentally contaminated surfaces (plastic, metal or glass) at room temperature http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote61. In another study, Ebolavirus dried onto glass, polymeric silicone rubber, or painted aluminum alloy is able to survive in the dark for several hours under ambient conditions (between 20 and 250C and 30–40% relative humidity) (amount of virus reduced to 37% after 15.4 hours), but is less stable than some other viral hemorrhagic fevers (Lassa) http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote53. When dried in tissue culture media onto glass and stored at 4 °C, Zaire ebolavirus survived for over 50 days http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote61. This information is based on experimental findings only and not based on observations in nature. This information is intended to be used to support local risk assessments in a laboratory setting.

A study on transmission of ebolavirus from fomites in an isolation ward concludes that the risk of transmission is low when recommended infection control guidelines for viral hemorrhagic fevers are followed http://www.phac-aspc.gc.ca/lab-bio/res/psds-ftss/ebola-eng.php#footnote64. Infection control protocols included decontamination of floors with 0.5% bleach daily and decontamination of visibly contaminated surfaces with 0.05% bleach as necessary.

The CDC gave the nurse permission to fly back to Dallas ! Who gave her permission to fly to Ohio in the first place.

DALLAS — The second Dallas nurse diagnosed with Ebola shouldn't have traveled on a commercial flight due to her exposure to the virus prior to her diagnosis, said Tom Frieden, director of the Centers for Disease Control and Prevention.

But the CDC has now confirmed that it gave Amber Vinson permission to return to Dallas by air after making a trip to Ohio.

However, because of her exposure to the virus, Vinson shouldn't have traveled on the commercial flight, the CDC director said on Wednesday. Frieden revealed the nurse registered a low-grade fever of 99.5 degrees before she boarded the plane.

It was later confirmed that the CDC gave Vinson permission to get on the plane because she was showing no other symptoms of the virus, and her temperature didn't reach the threshold of 100.4 degrees.

Where did they get that specific number from, out of a hat!

Well, until now, it has been widely accepted/believed that Ebola is only transmissible by contact with fluids: blood, vomit, feces, sweat, . . . . from infected patients. However, apparently University Of Minnesota CIDRAP Researchers claim Ebola Is airborne!

Ebola is airborne, according to a new report by the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota.

Purely anecdotal but I happened to be at a Kaiser clinic today and asked if they had been trained or briefed on dealing with Ebola. The answer was no even though the government has claimed that the DC metro area is ready if we have a case. I would think that being 'ready' would include training the medical personnel who may encounter patients with Ebola. I find it very disturbing that so little seems to be getting done given the spread of the disease. Unfortunately, it appears that hospitals won't do anything until it lands on their doorstep.

I don't think they mean airborne in the sense of the flu, and in fact, they decided to not use the world airborne to describe it; instead, they are talking about what happens if particles of blood, vomit, feces, etc get put into the air (for example, by flushing a toilet).

I had to go get my toe looked at today at an Urgent Care clinic in Tacoma (sigh, an infection due to a toe trauma I got while hiking last weekend - antibiotics seem to be working though!). Before they would even ask me what I was there for, I had to fill out a form with three questions: Have you recently traveled to West Africa? Have you been in proximity to someone with symptoms of Ebola (list of symptoms)? Are you experiencing a fever, diarrhea, or vomiting? Then they checked me in as normal.

I was happy to see they're at least asking relevant questions.

Honestly I was much more concerned with the people who were there with flu. They give those people masks to reduce the chance of contagion, and they looked pretty miserable. Flu is hitting early this year, and my flu shot isn't scheduled until October 29!

An adult oral temperature of 100.4 is just the standard definition of a medically significant fever. They recommend that you do not treat anything under that. If you Google "fever temperature", you will see 100.4 a lot. Considering how fevers fluctuate during the day, it is probably a bad standard to use for ebola risk.

This is what I was waiting to hear:

Dallas Hospital Letter to the Community 101914 [text version]
...
Many are speculating about how Ms. Pham and Ms. Vinson. both skilled and careful nurses. became infected
despite their compliance with the protective equipment and safety procedures. Our focus is on the facts,
and we are determined to get all of the answers as soon as we can. We have interviewed our staff and reviewed
our records and are bringing in outside expertise to completely analyze what happened and how.

Based on what we already know. I can tell you that many of the theories and allegations being presented in the
media do not align with facts stated in the medical record and the accounts of caregivers who were present
on the scene.
We have remained committed to complying with CDC guidelines from the start: we believe our
procedures complied with the CDC Ebola guidelines and our staff implemented them diligently.

As we look into and analyze what happened, we are interviewing those who participated in Mr. Duncan's care
and are encouraging staff with information and insights related to his care to share those with our team to help
us learn from this event.
...
(bolding mine)

Having retired recently from working 29 years in a Hospital, two nurses getting Ebola didn't make much sense to me, given what has been publicized as transmission modes.

I would share an anecdotal story of how I was exposed to Hepatitis by a patient one day, 28 years ago, but I've heard anecdotal stories are frowned upon.

Nigeria could have had an outbreak of Ebola, but for one doctor!

How 1 doctor saved Nigeria from Ebola catastrophe
http://news.yahoo.com/ebola-nigeria-hero-doctor-adadevoh-122828747.html
A day after the World Health Organization https://news.yahoo.com/nigerias-ebola-outbreak-officially-over-104227798.html , the doctor who treated the country's first case of the deadly virus and later died from the disease herself is being hailed as a hero for helping stop the outbreak.

Dr. Stella Ameyo Adadevoh, a doctor at First Consultant Hospital, oversaw treatment of Patrick Sawyer, Nigeria's Ebola patient zero, when he arrived sick in Lagos, Nigeria's former capital and Africa's largest city, on a flight from Liberia in July.
. . . .
Adadevoh, the Telegraph writes, "effectively saved the country from disaster by spotting that its first Ebola patient was lying about his condition, and then stopped him leaving her clinic."

Sawyer, who had been caring for his Ebola-stricken sister, was reportedly set on visiting one of Nigeria's Pentecostal churches "in search of a cure from one of the so-called miracle pastors," the BBC said.

That is interesting, except that I thought it was smallpox - cowpox? People who had been infected with cowpox were immune to smallpox. I will have to ask a milk maiden if I can find one.

Reston virus (RESTV) is one of five known viruses within the genus Ebolavirus. Reston virus causes Ebola virus disease in non-human primates; unlike the other four ebolaviruses, it is not known to cause disease in humans, but has caused asymptomatic infections.

Of course I meant "cowpox". Thank you. It is fixed.
People who had been infected with cowpox were immune to smallpox. I will have to ask a milk maiden if I can find one.

While reading about the Reston Ebola virus, I ran across a couple that have an extensive history, studying the virus: Dr. Joseph McCormick and his wife Dr. Susan Fisher-Hoch

I then found an interesting article posted 3 weeks ago (ancient history).
EBOLA: WHY THIS OUTBREAK IS UNLIKE ANY OTHER OF THIS DISEASE...
During their field studies, Fisher-Hoch and McCormick heard many of the same fears being voiced today, that somehow Ebola is now airborne.
McCormick said, "One, we have not seen the evidence. Two, we don't have any evidence of other viruses having done that. And so I think that we are, we can safely argue, continue that this is not airborne."
But the couple says this outbreak is different. In the past, Ebola killed only a few hundred people. This time, thousands have died. They say the reason has more to do with humans than Ebola.
Fisher-Hoch said, "The conditions, the average living conditions, the squalor, the poverty, the crowding are horrendous really. So that allows a virus to spread around."
Dr. McCormick says what angers him the most about the current outbreak is that two potential vaccines were identified a decade ago, but there was no serious interest to develop them until now. ...

hmmm... I suppose I should have just googled PF in the first place:

There is something seriously wrong with the PPE requirements and procedures if medical personnel are getting sick and this doctor thought it was safe to be in public so soon after arriving from a hot zone after being in direct contact with infected victims.

This! This has been bugging me all along. I think there's some kind of subliminal thinking among Westerners who, when confronted with the fact that African medical workers are being infected at high rates, might think: oh, it's because they don't have Western training or equipment, it's because they're poor. Total BS, IMO! These doctors and nurses are professionals. Every day, they do the same procedures Western docs do: set bones, stitch wounds, assist births, perform surgeries. They know how to protect themselves from diseases Western medicos only see once or twice (or never) in their careers.

The PPE protocol should be getting a close review, IMO.

As far as the doctor who just tested positive, I wish him all the best.

There is something seriously wrong with the PPE requirements and procedures if medical personnel are getting sick...
Did you read some of the things the nurses union was saying about the Texas PPE protocols? The protocols they did receive didn't work. After complaining that their necks weren't covered, they were instructed to wrap themselves in surgical tape! Unbelievable.

I wish the doctor well too but I don't think he should have been bowling or having close contact with others until the possible incubation period had passed.

This just tells me that the doctor considered that there was zero risk that he had been infected, based on available information.

I contracted whooping cough about 10 years ago. It is also not considered an "airborne" transmissible disease. Yet, its infection rate is staggering.
I was working in a hospital at the time, and although there was a "this is not a problem" official attitude, a friend working in the pharmacy confided that Pertussis inoculations had been ordered for all doctors and nurses.

If a patient sneezes, or coughs, and a doctor, moments later, walks into their room, what's to keep him from catching it?

It's still my guess, that this is not a PPE problem.

And I'm not implying that Pertussis is anything nearly as bad as Ebola, I'm only inferring a potential transmission mode.

Pertussis in Other Countries
Worldwide, it is estimated that there are 16 million pertussis cases and about 195,000 pertussis deaths in children per year. Despite generally high coverage with childhood pertussis vaccines, pertussis is one of the leading causes of vaccine-preventable deaths worldwide. Most deaths occur in young infants who are either unvaccinated or incompletely vaccinated.

Hopefully, the clinics the Army Corp of Engineers are building in the affected nations, have no windows.
Sometimes, western technology, makes things worse.

Logically it seems that assumption of near zero risk is flawed in some way.

A three-week quarantine makes sense for anyone "with a clear exposure" to Ebola, said Dr. Richard Wenzel, a Virginia Commonwealth University scientist who formerly led the International Society for Infectious Diseases.

Some health workers could "have a kind of denial there are any exposures," and an automatic quarantine would address that, Wenzel said.

At the same time, he conceded health workers might be leery of volunteering if they knew they would be confined to their homes for three weeks after they got back.

Graham said the federal government should rent out a hotel — perhaps one in the Caribbean, to ease public fears — and then staff it with doctors and quarantine all returning health care workers there for three weeks.
I might volunteer for a three week Caribbean vacation.

Reuters) - The Obama administration is considering quarantines for healthcare workers returning from Ebola-ravaged West African countries, an official said on Friday, as authorities in New York retraced the steps of a doctor with the disease.
...
Dr. Anthony Fauci, director of the NIH's National Institute of Allergy and Infectious Diseases, said he could not pinpoint anyone factor that contributed to Pham’s speedy recovery. He said it could be any of a number of factors, including the fact that “she's young and very healthy” and was able to get intensive care very quickly.

Pham received donated blood plasma from Dr. Kent Brantly, who contracted Ebola working in Liberia for a Christian relief group and survived after being treated with an experimental drug. Brantly was released from a hospital in August.

It's good to see that early treatment works so fast.

Many New Yorkers were dismayed to learn that in the days after he came home, Dr. Craig Spencer rode the subway, took a cab, went bowling, visited a coffee shop and ate at a restaurant in the city of 8 million.

Spencer, a 33-year-old emergency room doctor, returned to the U.S. on Oct. 17 and sought treatment Thursday after suffering diarrhea and a 100.3-degree fever. He was listed in stable condition at a special isolation unit at Bellevue Hospital Center, and a decontamination company was sent to his Harlem home. His fiancee, who was not showing symptoms, was being watched in a quarantine ward at Bellevue.
So he returned home Oct 17, and by Thursday, Oct 23, he was seeking treatment for symptoms that were indicative of Ebola, after he returned to New York City from treating Ebola patients in Guinea. He should have quarantined himself!

So now - after the fact - NY, NJ order Ebola quarantine for doctors, others arriving from West Africa and who may or did have had contact with victims of the disease.
http://news.yahoo.com/1st-ebola-case-nyc-3-others-quarantined-060226282.html Why don't Ebola doctors returning from West Africa quarantine themselves?
'As long as a returned staff member does not experience any symptoms, normal life can proceed,' Doctors Without Borders says
http://news.yahoo.com/why-dont-ebola-doctors-self-quarantine-140038847.html
According to Dr. Mary Travis Bassett, New York City's health commissioner, "Spencer had been taking his temperature twice a day."
Yahoo said:
He began feeling sluggish on Tuesday but did not develop a fever until Thursday at 11 a.m., when he discovered he was running a 100.3-degree temperature. Spencer alerted Doctors Without Borders, which in turn alerted New York health officials.
Meanwhile, back in W. Africa - Mali reports first case.
http://news.yahoo.com/doctors-without-borders-ebola-risk-cant-zero-120707049.html

BAMAKO, Mali (AP) — Many people in Mali are at high risk of catching Ebola because the toddler who brought the disease to the country was bleeding from her nose as she traveled on a bus from Guinea, the World Health Organization warned Friday.

The U.N. agency is treating the situation as an emergency since many people may have had "high-risk exposures" to the 2-year-old girl during her journey through several towns in Mali, including two hours in the capital, Bamako. The girl was traveling with her grandmother.

It's suspected in some circles that Ebola transmits via aerosols.
http://www.cidrap.umn.edu/news-pers...ers-need-optimal-respiratory-protection-ebola
We believe there is scientific and epidemiologic evidence that Ebola virus has the potential to be transmitted via infectious aerosol particles both near and at a distance from infected patients, which means that healthcare workers should be wearing respirators, not facemasks.1

Here's their reference 1:
http://www.ajicjournal.org/article/S0196-6553(07)00774-2/abstract
Conclusion
None of these surgical masks exhibited adequate filter performance and facial fit characteristics to be considered respiratory protection devices.

A few TV news reports have shown personnel wearing face protection with an external air hose, suggesting they're full face respirators like I'm used to from the Nuke plant.

This is how we learn, by experience.
