The H5N1 virus remains mainly a virus of birds, but experts fear it could change into a form easily transmitted from person to person and sweep the world, killing millions.
So far, most human cases can be traced to direct or indirect contact with infected birds.
Initial tests usually take a day or two to confirm if someone has H5N1. More detailed testing by government laboratories or those affiliated with the WHO can take a week or more. (Writing by David Cutler and Keith Weir, London Editorial Reference Unit)
