I think this goes to the disconnect in the public perception and fuels the panic. It is hard to be infected by someone in the early stages, but it is incredibly infectious in the later stages. This is why nurses and doctors and other primary care providers have such high infection rates. This is why is spreads so much in the cultures with burial rituals that involve touching, cleaning and kissing the corpse.
This is why it is very unlikely that the people on Vinson's flight (and everyone else in Cleveland) have been infected. And why we can all take a breath and begin to look at the light of the end of the Ebola in the US tunnel. Until the next person brings it in.
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.

(8,303 posts)The new CDC recommendations are lightyears away from the previous version:
http://www.cdc.gov/vhf/ebola/hcp/procedures-for-ppe.html
It also requires a lot of preliminary work to set this up, so now all the hospitals have to work on this. CDC's recs were flat-out inadequate, but that has now been remedied. The important thing now is to ensure that intake facilities are adequately prepared, because this is not an on-the-fly care situation at all.
BlindTiresias
(1,563 posts)I strongly suspect he knew he was infected and isolated himself from the rest of the family. The two groups that are at the absolute highest risk are healthcare workers and family members in a caretaker role. The fact none of them were infected is really suspect in that light.

And that time could happen on an airplane, to a person with a fever of "only" 100.
morningfog
(18,115 posts)As the article makes clear, it is the viral load, not just vomit that increases infectivity.
The "so what" is that people are overreacting across the country because they don't understand that people infected with Ebola start by not being infectious at all (during incubation) and become more infectious as they worsen and die, because the virus builds up. That is why the CDC approved Vinsons flight. Her fever was so low and she had no other symptoms, therefore she was not very infectious. Like living with Duncan with MUCH worse symptoms didn't infect anyone, flying next to a 99.5 temp infected person was so little a risk, the flight was fine. Get it?
LisaL
(44,973 posts)Do you think they like tracing hundreds of people that flew with her? Over hundred of people are being monitored or in quarantine. Do you think they like doing all of this extra work they could have prevented by telling her to not fly?

morningfog
(18,115 posts)CDC knows the risk is slight to nil. They are covering their ass now.
Should she have been cleared to fly? Probably not. It was really poor PR.
Was anyone on that flight actually at risk or infection? Probably not.
pnwmom
(108,980 posts)We only know with hindsight that they most likely were not infected. But they were at risk the moment a person with an Ebola infection got on the plane -- because she could have suddenly gotten sicker during the hours of the plane ride.
And the CDC knows that, and that's why they say they should NOT have recommended that she fly.

They also understand that there WAS a significant risk in letting her fly because she could have vomited during the flight. THAT'S why they're saying they made a mistake. Not because of "poor optics." They aren't manipulating public opinion now. They were just wrong to let her make that flight.

What was unknown before she flew is known now. She didn't vomit or bleed or shit on anyone. The actual risk that anyone on the plane was infected is close to nil.

Warren DeMontague
(80,708 posts)But it's lethal enough that it's better to not screw around with it. A small unnecessary risk is still too high when you're talking about such a horrific potential outcome.
On the flip side, it was obviously more transmissible later on than someone thought, because now 2 nurses are infected with it.
Fumesucker

(80,708 posts)The early criticism I read about some of the first CDC guidelines involved Nurses not having shoe covers. It doesn't take a genius to see where you might have a problem with a nurse walking into a room with a very sick ebola patient, cleaning them up, and then walking around the rest of the hospital.
So yeah, I'd put what you said in that category. Which is not to say that anyone caught it that way, this time.

Frankly the full-court press coming down from the media around stuff like suspending visa travel, is kind of strange, you know, about what a terrible awful no-good horrible idea such suggestions are... the only other times I've seen this kind of inexplicable media unanimity is in the early days of people talking about legalizing pot or ending the drug war (TERRIBLE idea!) or the early days of talking about invading Iraq (GOTTA DO IT, just.. because!)

This is not an easily transmitted virus despite all the "experts" here on DU who said otherwise.
wercal
(1,370 posts)Fairly low odds of disaster....but that small chance can be a disaster.
Duncan spent two days in the apartment...after he felt so terrible he felt the need to go to a hospital. And he threw up when the paramedics picked hin up. He was probably very infectious....and its just a miracle nobody else was infected.
I consider it a near miss...not confirmation that ebola is harmless.
morningfog
(18,115 posts)That would be silly.
wercal
(1,370 posts)I don't care if somebody is in day 1 or day 15 after infection. They should both be treated as highly infectious. This notion that its 'ok' to fly with only a low Ebola fever....because it 'probably' won't infect anyone is truly what is silly.
morningfog
(18,115 posts)Zero.
You don't know if someone had been infected until usually day 7-10 after exposure. And if they only show a fever that are not "highly infectious." The virus builds in the body overtime, eventually to the point were they are highly infectious. But it doesn't start that way.
I agree that she shouldn't have flown. It is bad optics for those trying to portray competence and control.
But, she did. And most importantly, the risk to others on the plane was extremely low. So low, in fact, that I am comfortable saying no one on the plane was infected. Everyone will see that to be so in a couple of weeks.
wercal
(1,370 posts)It technically cannot be zero. Vinson did indeed have the virus in her, albeit in small quantity. But all it takes is that one unfortunate expulsion of that virus and somebody else is infected.
There is alot that is not known about Ebola...like where it hides between outbreaks. There are theories but nobody knows for sure.
Have you ever considered that the means of one patient's infection changes how infectious they are? For example, mayber Pham got it in her mouth and the infectiin is completely internal for the first few weeks. But what if Vinson got it in here eye...and her tears have been infectious from the very beginning. You can't tell me that you KNOW it couldn't happen this way....because nobody does.
The CDC isn't quarantining people for 'optics'....they do it because nobody really knowshow contagious it is.
morningfog
(18,115 posts)There is not a high enough viral load for it to leave the body. An asymptomatic person is at zero risk of infecting another person. Zero. None.
Yo_Mama
(8,303 posts)In casual contact, of course the risk is very low. You really aren't going to get the virus by sitting on the bus or whatever to a person who isn't overtly symptomatic.
But the risk of transmission comes if bodily fluids are exiting the body with virus in them and you are exposed to them. A person may have no extreme symptoms but a level of virus high enough in the blood to infect.
In the HC system, a lot of infections have been transmitted before an individual was ill enough to generate a suspicion of Ebola, most commonly in OB/GYN clinics & wards in Africa.
In the common spaces under normal conditions, the isolation procedure is necessary to prevent accidental exposures only (such as cut, fall, etc). You're saying something that is not true, which is why quarantine facilities have been set up all over Africa, and why public health have instituted isolation procedures for those who may have been exposed here. There's no other way to do it.
wercal
(1,370 posts)...yet they are. And asking them to self monitor. And as far as I k ow, the boyfriends of both infe ted nurses have been self quarantined.
These things are not done because the risk is zero. They are done because, while the risk is extremely low, it still is there.
morningfog
(18,115 posts)The risk of someone who is asymptomatic is zero.
The risk of someone with a low fever and nothing more is very very low, but I not zero.
wercal
(1,370 posts)And trying to clearly say you are wrong.
An infected person even without symptoms has the virus in him correct? Even if its just one, he is carrying it around....and the risk of transmission cannot by definition be zero.
I can tell you don't believe that - but its true.
If I got Ebola on Monday, and you put me in a wood chipper on Tuesday, and a group of people ate my raw remains in ten minutes, somebody in tbe group will have ingested a live Ebola virus. Why? Because the virus was in me...sure in small quantity, but its there...and in this scenario exposure to the virus is unavoidable.
Now that is an umrealistic example. But I gave a much more realistic one about being I fected in the eyes. Just about everything known about Ebola is anectdotal....which leaves alot of gaps in our knowledge....so my eye theory isnt outrageous and its quite possible. Or particles of snot from a sneeze could transmit the disease, if the virus had recently entered the nose. Etc...etc. Whatever part of the body that first got infected could rapidly become infectious to the external world, long before its spread throught the body.
morningfog
(18,115 posts)It doesn't infect at the entry and spread. It gets into the blood and then spreads to organs. Early on there is simply not enough in the blood to spread and infect someone else, not by any means.
"When you are first infected, you are actually not contagious," because levels of the virus in blood are too low to spread the infection, Hotez says. "Even in the early days of an infection, the virus is not easily transmitted from person to person because it requires direct contact. Ebola is not associated with respiratory transmission. So you don't get Ebola just from sitting in the same room with someone."
Even doctors and nurses who treat Ebola patients in an emergency room would be at a lower risk, because patients at this early stage are not shedding huge amounts of virus. While the Ebola virus can live on surfaces, those surfaces would have to be covered in blood. The virus doesn't usually spread from coughing or touching objects in public places, such as doorknobs.
The risk goes up exponentially as the virus gains ground in the body, however, because Ebola has a "unique ability" not seen with other viruses, Hotez says.
http://www.usatoday.com/story/news/nation/2014/10/14/ebola-spreads-easily-hospitals/17247157/
In fact, a significant number of people are infected with Ebola but never show symptoms because their body fights it off. They are also NEVER contagious. If you are exposed to an Ebola patient early, even if you develop symptoms, you are more likely to be able to recover. It is a very interesting virus.

uppityperson
(115,677 posts)There is minimal risk,thiugh still very low risk,before showing symptoms. When symptoms appear, there is enough risk to be risky. As the disease progresses, the risk increases. After death, the bodies are very risky and now not only caregivers but other family and friends are exposed and infected by patting and kissing the dead person. Not something commonly done in the USA, but cultural norm in many places in W Africa where it is spreading.
There is a risk or a meteorite falling through my roof and hitting me on the head. Not much risk, but still a risk. There is a higher risk of me being in a car accident on the way to work. The first of these I spend no time worrying about, the second I take precautions to avoid.
There is risk, but I would rather spend my energies avoiding the higher risk sort.
TBF
(32,067 posts)I'd be very focused on the safety gear the caregivers are wearing. Identification of folks with Ebola, isolate, and be very careful when treating. From the diagrams/photos I've seen it looks like the nurses in Dallas weren't wearing enough or correct protective gear. That is something that can be immediately corrected in future cases.
