A man in Mexico died with one form of bird flu, but U.S. officials remain focused on another --Experts say the mysterious death of a man in Mexico who had one kind of bird flu is unrelated to outbreaks of another bird flu at U.S. dairy farms | 6 June 2024 | The mysterious death of a man in Mexico who had one kind of bird flu is unrelated to outbreaks of a different type at U.S. dairy farms, experts say. A 59-year-old man in Mexico who had been bedridden because of chronic health problems developed a fever, shortness of breath and diarrhea in April. He died a week later, and the World Health Organization this week reported it. The WHO said it was the first time that version of bird flu -- H5N2 -- had been seen in a person. A different version of bird flu — H5N1 -- has been infecting poultry flocks over the last several years, leading to millions of birds being culled. It also has been spreading among all different kinds of animals around the world... Mexico Health Secretary Jorge Alcocer said kidney and respiratory failure -- not the virus -- actually caused the man's death. Some experts said it is noteworthy that it's not known how he caught the man caught H5N2.
