The World Health Organization (WHO) has confirmed the first human death from a new strain of bird flu, A(H5N2), in a resident of Mexico. The individual, who fell ill in April 2024, marks a significant and concerning development in the ongoing monitoring of avian influenza. This new strain, part of the highly pathogenic avian influenza (HPAI) viruses, has primarily affected birds, but its detection in humans signifies a potential risk of broader transmission and necessitates increased vigilance and preparedness in public health responses.
WHO reported that the man had several underlying health issues and had been bedridden for three weeks before exhibiting severe symptoms. On April 17, he experienced fever, shortness of breath, diarrhoea, nausea, and general malaise. He sought medical care on April 24 and was immediately hospitalised at the National Institute of Respiratory Diseases (INER), but unfortunately, he passed away the same day. Following his death, INER health authorities tested samples from him, and on May 8, the Laboratory of Molecular Biology of Emerging Diseases Center for Research in Infectious Diseases found the sample positive for influenza A(H5N2). By May 22, the Institute of Epidemiological Diagnosis and Reference confirmed the strain.
The confirmation of this case comes amid a backdrop of rising instances of H5N1 avian influenza in various species, including mammals, which are biologically closer to humans. Since its emergence, this strain has spread across continents, causing significant mortality in poultry and wild birds, and now, concerningly, in humans. The WHO, along with the CDC and other health organizations, emphasizes the importance of stringent biosecurity measures, enhanced surveillance, and rapid response strategies to contain outbreaks and prevent potential pandemics.
