Human Metapneumovirus (HMPV) has been in Bangladesh for decades despite recent outbreaks in Asia. Identified in 2001, it resembles the flu with symptoms like fever and cough, but no fatalities have been linked. Preventive measures, including masks and hand washing, are advised, especially for children, the elderly, and pregnant women. While there's no vaccine, HMPV isn't alarming but should be monitored for its respiratory implications.
