Ebola: UN health agency seeks to allay fears about air travel
14 August 2014
The United Nations World Health Organization (WHO) today sought to allay fears amid reports that airlines are suspending
flights over the Ebola outbreak by sending out a social media messages with assurances that “unlike infections like
influenza and tuberculosis, Ebola is not airborne.”
“The chance of having someone who is sick with Ebola getting in a plane is small,” WHO tweeted today. “Usually when
someone is sick with Ebola, they are so unwell that they can't travel.”
The agency, which also gave a press conference providing "clarifications" on air travel, has declared the current
outbreak in West Africa a public health emergency of international concern, while UN Secretary-General Ban Ki-moon has
appointed Dr. David Nabarro as Senior United Nations System Coordinator for Ebola, in support of the work done by WHO
Director-General, Dr. Margaret Chan and her team.
According to the latest WHO update, between 10 and 11 August, 128 new cases of Ebola virus disease, as well as 56
deaths, were reported from Guinea, Liberia, Nigeria, and Sierra Leone, bringing the total number of cases to 1,975 and
deaths to 1,069.
The agency said in that update that contact tracing in Guinea, Nigeria, and Sierra Leone has resulted in a range between
94 per cent and 98 per cent of contacts of Ebola cases being identified and followed-up, but in Liberia, efforts are
underway to strengthen contact tracing, but help is needed in this area.
WHO today said it is disappointed when airlines stop flying to West Africa. It is “hard to save lives if we and other
health workers cannot get in,” the health agency tweeted following a press conference.
“Ebola-affected countries, international airlines are putting systems in place to screen passengers for possible
infection,” WHO said. “Countries with big airport with high volumes of travellers are not the same as countries with
land borders with Ebola-affected countries.”
WHO has repeatedly said the Ebola virus is highly contagious – but not airborne. Transmission requires close contact
with the bodily fluids of an infected person, as can occur during health-care procedures, home care, or traditional
burial practices, which involve the close contact of family members and friends with bodies.
The incubation period ranges from 2 to 21 days, but patients become contagious only after the onset of symptoms. As
symptoms worsen, the ability to transmit the virus increases. As a result, patients are usually most likely to infect
others at a severe stage of the disease, when they are visibly, and physically, too ill to travel.
The highest Ebola virus level is found in a dead body, according to WHO, hence, currently the highest risk of Ebola
transmission is during burial ceremony.
