Ebola: WHO emergency team holds Talks On Travel Restrictions.
The meeting in Geneva will examine screening measures at borders and consider whether stricter travel regulations should be put in place.
New rules in the US require travellers from the worst affected countries to arrive at one of five airports.
Meanwhile, first batches of an experimental vaccine against Ebola are due to arrive to Switzerland.
The vaccine, developed by Canada’s public health agency, combines fragments of Ebola with a non-fatal virus and could trigger the immune system to produce the necessary antibodies.
However, the BBC’s Imogen Foulkes in Geneva says a fully tested and approved vaccine is not expected to become available for months or possibly years.
The current outbreak of the virus has already killed more than 4,500 people – mostly in Guinea, Liberia and Sierra Leone.
