Suggesting Ebola will become airborne is 'irresponsible', say experts
UN's Anthony Banbury criticised as irresponsible and spreading panic for suggesting that Ebola could become airborne when no other virus has changed in this way The UN's chief of Ebola mission Anthony Banbury said Ebola could become airborne in a 'nightmare scenario' but leading scientists have slammed his remarks saying this has never happened and suggesting it is 'irresponsible'. Mr Banbury was speaking exclusively to the Telegraph as predictions were made that Ebola could have infected 1.4m people by January. He said the longer the virus is in humans the greater the chance it could mutate. He said the virus being spread through the air was a 'nightmare scenario' but that it 'could not be ruled out'. However leading British scientists have rounded on him saying his comments are a distraction and accused him of spreading panic. Professor Peter Piot, director of the London School of Hygiene & Tropical Medicine, and co-discoverer of the Ebola virus, said: "To suggest that Ebola could become airborne is completely irresponsible. "The way the virus is spreading is consistent with what we've seen in all previous 25 outbreaks, only transmitting through blood and bodily secretions. There is no precedent for a virus changing its mode of transmission so drastically. "Other viruses such as HIV – which transmit in the same way, have passed through millions of humans, and are known to mutate more than Ebola – have not become airborne. Making such claims is an unwelcome distraction from the urgent need to scale up the international response to the ongoing humanitarian crisis in West Africa." Dr Ben Neuman, Lecturer in Virology at University of Reading, said: “Ebola is found in the bloodstream, which is part of what makes it so difficult to transmit compared to other viruses. To become airborne, Ebola would need to fundamentally change the way it grows. That is very unlikely in my opinion. “Evolution can be unpredictable, but there is no good reason to expect that Ebola will become more dangerous with time. Severe diseases like Ebola often happen when a virus clashes with a brand new host for which it is poorly adapted. Recent experience with H1N1 swine flu shows that viruses are likely to mellow as they adapt to their new hosts. “There is no evidence that Ebola can spread via the air in the real world. Ebola can only be transmitted through the air under carefully controlled lab conditions. One clue that emphasises how different Ebola is from flu is how slow the virus is spreading. Compared to this Ebola outbreak, the H1N1 swine flu had already spread to an estimated 10,000 times as many people in its first ten months.” Dr Jeremy Farrar, Director of the Wellcome Trust, added that a sense of proportion should be kept when discussing Ebola. “The chances of Ebola becoming airborne are extremely small. I am not aware of any viral infection changing its mode of transmission. It’s important we retain a sense of proportion and not exaggerate the risks for it changing and becoming airborne," he told the Telegraph. "There is already enough fear and panic surrounding this epidemic. "Of more concern is that the virus could become endemic in Western Africa, so unlike big outbreaks like this we could have smaller numbers of cases but circulating continuously. This is where we need to focus our efforts and attention – on trying to stop this outbreak before it establishes itself in Western African countries.” Mr Banbury, who has served in the UN since 1988, said that the epidemic was the worst disaster he had ever witnessed. “We have never seen anything like it. In a career working in these kinds of situations, wars, natural disasters – I have never seen anything as serious or dangerous or high risk as this one. I’ve heard other people saying this as well, senior figures who are not being alarmist. Behind closed doors, they are saying they have never seen anything as bad,” he said. He is leading a mission to Africa with the aim of getting the outbreak under control within 90 days. He added: “There is a limited window of opportunity. We need to hit it and we need to hit it hard. We haven’t done that but we are doing it now. "Certainly we are late but the expectation is that we are not too late. We are going to have a very big, fast effort … I have never seen the UN move at this speed or with such co-ordination. We are seeing the kind of response we need, but yes, it’s a bit late.” The latest figures from the World Health Organisation show that as of last week there 7178 cases, with 3,338 deaths. Countries affected are Guinea, Liberia, Nigeria, Senegal and Sierra Leone. http://www.telegraph.co.uk/news/worldnews/ebola/11138196/Suggesting-Ebola-will-become-airborne-is-irresponsible-say-experts.html |

I understand Professor Piot's great grandfather sailed on the Titanic I love it when people say something could NEVER happen |

I am so tired of one 'camp' slamming the other in this debate.
If no one speculated, questioned, debated the status quo, science would never move forward. In this specific circumstance, when it comes to the guy in charge saying something plenty of scientists have already mentioned, it is overstepping for other scientists to call him out on it. Those scientists are one side of a debate. They are not admin professionals for public health. If Banbury thinks making that statement will actually help to muster support and spur action, he's probably right. Scientists for both sides of the debate need to get off their soap boxes and back into the lab. Shouting ever louder will not save lives or prove anyone right, but some more evidence might.

JD- I would never say Ebola couldn't go airborne because as we all know in nature all is possible! I believe the length of this virus (14,000 NM) makes it to bulky to aerosolize. Also the fact that people are not infectious until showing symptoms makes this disease very containable. I'm still much more worried about influenza (Length 200-300 NM) ! Ebola has killed 4,000-5,000 people in less than a year and so far all cases outside of West Africa have been imported. In 1918 there were 25 million deaths in the first 25 weeks! That's what I call airborne!! Universal precautions, solid case tracing and good hygiene could have stopped this months ago! Ignorance, fear, tradition and poor sanitary conditions in urban environments is what let this get out of hand. I guess the fear of it going airborne may prompt politicians around the world into action but I find it sad that it takes this kind of fear mongering to get the world to do the right thing!

Look, if you were to pile several Ebola mortalities on some dynamite & blow it off then, yes, the Ebola would become airborne, for a short time.
Otherwise, fuggetaboutit. It takes thousands of years for viruses to change their basic transmission pathway, no one in the field can think of a good example. Mutations that aid infection in human, rather than animal, hosts happen frequently, but are not a guarantee. We are still waiting for H5N1 to mutate in this manner, so far, nothing. I don't think H5N1 will ever make that step, unless Kawaoka lets one out of his lab in Wisconsin.

Hi Happy Camper, great name! This ongoing Ebola originated in the country of Guinea and spread into neighboring Sierra Leon and Liberia. Once Liberian case, Patrick Sawyer, took a jet to Nigeria and infected several people over there, but no new cases have been identified in a while. A few cases have popped up in Congo, and the US has the only non-African case I'm aware of. Keep in mind that Ebola has erupted in the past....countries with prior outbreaks include Sudan, Uganda and others. This is a very comprehensive map of historic outbreaks, but it is not updated to show cases in Nigeria and Sierra Leon: |
