A 59-year-old man in Mexico has died with a type of bird flu - H5N2 - never recorded in people before now. There is no risk to the wider public, say authorities, and none of the man's close contacts have caught the virus. It is unclear how he got it, although there have been cases in some poultry farms in Mexico.

A person with prior health complications who had contracted bird flu died in Mexico in April and the source of exposure to the virus was unknown, the World Health Organization said on Wednesday.
