Man dies of bird flu strain not previously detected in humans

The World Health Organization announced that a man in Mexico has died from H5N2, a new strain of bird flu that hasn't yet been detected humans until now.

The WHO said it was first notified of a human H5N2 infection on May 23 related to a 59-year-old Mexico resident.

"Although the source of exposure to the virus in this case is currently unknown, A(H5N2) viruses have been reported in poultry in Mexico," WHO said in a statement.

In the announcement, the WHO said the man didn't have a known history of exposure to poultry or animals but did have some underlying medical conditions. He was suffering from "acute symptoms of avian flu" prior to the bird flu infection, according to reports.

On April 17, the man had a "fever, shortness of breath, diarrhea, nausea and general malaise." He ultimately died as a result of the bird flu infection. 

The organization also said that the current risk to the general population is low.
