Mexico recently identified its inaugural human case of H5N1 avian influenza, commonly known as bird flu, in a three-year-old girl based in the northern state of Durango, as per the health ministry's announcement on Friday. The young girl, presently hospitalized in critical condition, tested positive for the infection on Tuesday.
According to the health ministry, there is currently no evidence suggesting sustained human-to-human transmission of the virus. The World Health Organization (WHO) has deemed the public health risks posed by the H5N1 virus to the general population as low.
Since 2020, a potent variant of the H5N1 strain has been circulating globally among animals, leading to devastating outbreaks in commercial poultry and sporadic infections in various other species including alpacas and house cats. Notably, H5N1 was recently identified in cows for the first time.
The economy of Durango heavily relies on agriculture, particularly the cattle industry, pointing to the relevance and potential implications of this latest case in that region.
In a separate incident last year, Mexico reported its premier laboratory-confirmed human case of infection with the A(H5N2) bird flu in an individual with no known animal exposure, who subsequently passed away due to chronic illness.
