A human case of the H9N2 bird flu virus was confirmed by World Health Organization (WHO)
On June 11, the World Health Organization (WHO) confirmed a human case of the H9N2 bird flu virus in a four-year-old child in West Bengal, India.
Following three months of diagnosis and treatment, the child with the flu was discharged, as reported by Reuters. The WHO indicated that the child had been in contact with poultry at home and in the surrounding area, though no other family members or contacts reported respiratory illness symptoms. The patient’s vaccination status and details of antiviral treatment were not disclosed at the time of the report. This case is the second recorded instance of human infection with the H9N2 virus in India; the first case occurred in 2019. The H9N2 flu virus generally causes mild illness in humans, but the WHO has warned of the possibility of sporadic human cases. This is due to the widespread presence of H9N2 in poultry across various regions, which increases the risk of human exposure. The H9N2 strain is one of the most common avian influenza viruses found in poultry and has been identified in multiple regions worldwide. Human cases, although rare, typically present mild symptoms, including fever, cough, and general respiratory distress. However, close monitoring and rapid response are crucial to prevent potential outbreaks.
The WHO emphasizes the importance of surveillance and control measures to manage the spread of avian influenza viruses like H9N2. This includes monitoring poultry populations, improving farm biosecurity practices, and educating the public about the risks of direct contact with infected birds. Health authorities in India are likely to increase surveillance and testing in poultry markets and farms, particularly in regions with reported cases of avian influenza. Enhanced biosecurity measures, such as controlling the movement of poultry and improving hygiene practices, are essential to reducing the risk of virus transmission to humans. The recent case in West Bengal underscores the need for continued vigilance and preparedness to address avian threats. It also highlights the interconnectedness of human and animal health, reinforcing the concept of One Health, which integrates efforts to achieve optimal health outcomes by recognizing the interconnection between people, animals, plants, and their shared environment. In summary, the WHO’s confirmation of the H9N2 flu virus in a young child in West Bengal is a reminder of the ongoing risks posed by avian viruses. While the immediate threat to public Health may be low, sustained efforts in surveillance, biosecurity, and public awareness are vital to prevent future cases and ensure prompt response to potential outbreaks.
