April 2 (Reuters) - The World Health Organisation (WHO) confirmed on Monday three Egyptian children were being treated in hospital for bird flu.

All three were in a stable condition, the WHO said. Egypt now has 32 confirmed cases of bird flu, of which 13 have been fatal. Worldwide, the virus has killed 170 people since 2003, according to the WHO.

At least 200 million birds have died or been culled.

Following is a list of confirmed human cases of H5N1 from the WHO in Geneva. Total cases include survivors.

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.

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.

* NOTE: Indonesia has reported 71 deaths from bird flu. The difference between Indonesian death figures and those of WHO is that Indonesia has not sent samples for suspected cases out for independent checking at WHO-affiliated labs for the past two months. WHO only uses cases confirmed at such labs for its statistics.
