(Web Desk Monitoring) — The World Health Organization (WHO) confirmed on Wednesday that a man in Mexico died from a strain of bird flu, identified as H5N2, as reported by The Hill.

The WHO stated that a 59-year-old man from Mexico passed away on April 24, the same day he was admitted to a hospital in Mexico City.

About a week before his death, the man began experiencing symptoms such as fever, shortness of breath, diarrhea, nausea, and overall discomfort.

According to the man’s relatives who informed the WHO, he had previously suffered from “multiple underlying medical conditions” and had been bedridden for three weeks prior to the onset of acute symptoms. He succumbed to “complications of his condition.”

The WHO clarified that the man had not been in contact with poultry or other animals before falling ill, and the source of his exposure to the virus remained unknown.

This marks the first recorded death caused by a bird flu strain previously unseen in humans, as per the WHO.

Unlike the H5N1 strain, which has caused recent outbreaks among livestock in the United States and infected three dairy farm workers, this particular strain carries a different risk level. The WHO assessed the current risk to the general population as “low.”

While Mexico has experienced other cases of H5N2 among its poultry, the WHO stated it had not established a link to the human case.
