Health experts warn that recent mutations in the bird flu virus, although not resulting in sustained human-to-human transmission yet, suggest a potential risk to humans. The avian influenza A (H5N1) outbreak in poultry farms is not new, often brought by migrating wild birds. However, in recent years, this virus has shown the ability to infect mammals. In 2023, it spread to various mammals, including otters and sea lions, indicating its adaptation to new hosts.
Dr. Rajeev Jayadevan, from the Indian Medical Association, highlights concerns about the virus’s ability to infect mammals, including cattle, raising the risk of transmission to humans. While no sustained human-to-human transmission has been recorded, the recent case in Jharkhand sparked fears. Fortunately, tests on quarantined individuals returned negative. However, the high mortality rate associated with bird flu underscores the importance of preventive measures, including regular handwashing and vaccination.
Though the World Health Organization states no current evidence of sustained human-to-human transmission, recent cases among cattle raise fresh concerns. Vigilance and preventive measures, such as good hygiene practices and vaccination, remain crucial in averting potential outbreaks.
