Global airlines association, IATA has said the World Health Organisation (WHO) is not recommending travel restrictions or border closures due to the Ebola outbreak and there would be a low risk to other passengers if an infected person flew, Reuters has reported. A WHO official said there was a chance it could change its advice on passenger screening. “We will update our travel advice in the next few days. It could be no revision; it could be a slight modification; it could be a revision. We just have to see,” said the official. The West Africa outbreak, which began in Guinea in February, has spread to Liberia and Sierra Leone. With more than 1,200 cases and 672 deaths, it is the largest since the Ebola virus was discovered almost 40 years ago.
