Merged So Ebola's back......

The virus already appears to have mutated significantly enough to cut its own fatality rate from 90% to 60%.

No, not really. It's a rare disease caused by at least four different viruses, which occurs almost entirely in some of the poorest and remotest areas in the world, and is very difficult to diagnose. It's simply not possible to give anything more than a best estimate of what the fatality rate actually is. How many mild cases are never known about? How many serious cases and deaths are never known about - remember a large part of the problem in the current outbreak is that many people in the area don't trust either the government or the foreigners trying to help them. Given that people are willing to run away from hospitals after they've been diagnosed, how many more never go to one in the first place? And of course, governments and the WHO don't actually agree on the numbers anyway.

Just looking at previous Zaire virus outbreaks, the fatality rate has been recorded at anywhere between 45% and 100%, with no correlation with time. There's just no way we can conclude that the virus has become less deadly. Maybe we're doing better (or possibly worse, although that seems less likely) at identifying and recording cases, maybe there's better treatment this time (there's no cure, but just having access to medical facilities makes a difference), maybe it's just a slightly different strain this time.
 
Someone infected with Ebola Zaire can be infectious but asymptomatic for 5-7 days. Further Ebola does infect other mammals, such as rats and bats,, as well as other primates; in fact bats are probably the main reservoir for the virus, spreading it to humans via bite.

However compared to Lassa fever (another viral haemorrhagic fever) Ebola not particularly infectious and tends to 'burn out' quickly; contact with rat feces can spread Lassa and there are ~300,000 cases annually (with 3-5,000 fatalities).

The WHO position on Ebola is that it's a deadly but localised disease requiring rapid response based on standard public health strategies.

Isn't that potentially frightening now it has reached airports?
 
NPR had a person more expert than I on that very thing about two hours ago (Orlando). The explanation is the doctors and related professionals working with Ebola patients are putting in 12-15 hours in 90+ oF conditions and wearing protective suits that make their temp exposure over 100F for a very long time. The implication is things that would be minor occur easier due to heat and lack of sleep. And may not even be noticed.......

As to on planes and in US, massively unlikely. Ebola goes real fast and well in African village/poverty conditions, not so much in the US........
Exactly. The poor buggers at the sharp end are overworked and understaffed (the standard in healthcare generally I'm afraid) and make mistakes. Plus they're in contact with the disease constantly.
All it takes is one mistake.

Yes, because virus evolution is the only possible cause of that drop. Physicians gaining experience, trying new treatments, and new facilities and equipment provided to the endangered areas are to be ruled out as a contributor to this drop.
There are also four Ebola strains in Africa:
Bundibugyo 32% overall fatality rate
Sudan 54%
Taï Forest 0%
Zaire 79%
For Ebola Zaire untreated fatality rate is ~90%, with treatment this can be reduced to 50-60%. Fluids, anti/pro-coagulants, antibiotics/anti

Anybody been watching the Commonwealth games? What if there's some African athlete or associate who's already got Ebola?
So what? Unless s/he's biting people, having sex or otherwise sharing bodily fluids the infection chance is tiny.

The incubation period is said to be 3 weeks.
That's an outlier, >90% of those infected are symptiomatic to the point of seeking medical attention within 8 days. The problem is accurate diagnosis as the symptoms are basically the same as malaria.

I expect lots of paranoia until the current outbreak burns out, and numerous 'just-in-case' quarantines of possible carriers (as happened in the UK this week).

Let me quote Professor Peter Piot (one of the original 1976 team and an expert). He stated this week that the likelihood the epidemic could spread to the UK was "very, very, very low". He also stated that the infection risk from sharing a plane with an infected person was negligible: "By that I mean someone who is already infected but is not yet ill. Even in the early days when they have fever, that's also not risky for others".
And when the victim became contagious (bleeding and diarrhoeal)? "Even then you still need close contact. It's not like tuberculosis or SARS or the flu - that you can catch on a bus, but not Ebola".

"This is not a very contagious infection, you need close contact with someone who is really ill or who died from it".


The Commonwealth games closing ceremony is August 3rd. What if there's then a significant number of people flying home with flu-like symptoms?
And just how would they have been infected with Ebola in your paranoid fantasy?

Yes it's conjecture, yes it's unlikely, yes it's paranoid.
Correct.

But it's possible.
So is a major asteroid impact. In fact that's more likely. Worry about it.

And with ever-increasing population and international travel, pandemic isn't getting less likely. It's getting more likely. IMHO the risks are greater than all other concerns put together.
:confused: This is rubbish. Ebola is a concern, not some inevitable super-plague that will eliminate humanity.

As I said previously Lassa fever (a related disease) kills more people in three months than have died from Ebola since it was discovered.
 
"This is not a very contagious infection, you need close contact with someone who is really ill or who died from it".
Then it is indeed quite contagious, but not very infectious.

Yes, I know not everyone makes this distinction.
 
Isn't that potentially frightening now it has reached airports?
Not reallly. Someone who's infectious with Ebola almost certainly won't be able to travel and will be obvious.

... and Reston (similar to Ivory Coast (Taï), but with many seropositive humans who didn't develop it). It also circulated among pigs in Valenzuela City, Philippines)
Current WHO data doesn't consider Reston as disease causing in humans.
And it also appeared in Italy.

I think I won't be watching "Contagion" any time soon.......
Never watch such films with someone with epidemiological training, you may lose the TV from thrown objects. :)
 
Seen on Twitter:
Must resist urge to mark smart comment......

:rolleyes: Me culpa, I should have been more precise.

Of course this does mean war, and I will be monitoring your posts for imprecision.
 
The crackpots are starting to come out of the woodwork with the two Ebola patients being flown into the US,and the level of ignorance is astounding.
The nubmer of people citing the film Outbreak like it was a documentary is incredible.

I thought they could be infectious but asymptomatic for 5-7 days, which would be enough to allow them to travel.

Or am I missing something?

According to the CDC interview from a couple days ago, it's not contagious or at least not very contagious during the incubation period before symptoms begin.

The problem is the initial symptoms are fever and body aches, common to many infections.

I was perhaps a little unclear. At that stage they could infect someone, however they wouldn't be particularly dangerous, no bleeding and diarrhoea. Sex (perhaps there's some query about that in the early stage), or other direct exchange of fluids would be needed.
Casual contact wouldn't pose a danger.

Am I the only one who keeps thinking of the Ryan White era AIDS hysteria?
 
Just go to the comments sections of any major Media Website article on the Ebola outbreak, and you will lose a lot of your faith in the intelligence of Humanity.

First American Infected With Ebola Virus Arrives in U.S.

[Breaking news update, posted at 11:57 a.m. ET]

The medical plane transporting American Ebola patient Dr. Kent Brantly has landed at Dobbins Air Reserve Base in Georgia, the company that operates the plane told CNN. The patient is stable, and will be transported to Emory University Hospital.

Apparently he has now arrived at Atlanta hospital without incident.
 
Well, he was shown walking mostly under his own power into/toward the facility so...........
