Feb 3 (Reuters) - The World Health Organisation (WHO) confirmed on Saturday that bird flu killed a 22-year-old Nigerian woman, making her the first known human fatality of the H5N1 virus in sub-Saharan Africa.

Worldwide, the virus has killed 165 people since 2003, according to the United Nations health agency. At least 200 million birds have died or been culled.

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

Initial testing usually takes 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 within weeks or months.

So far, most human cases can be traced to direct or indirect contact with infected birds.
