Understanding Human Metanemovirus

Human metanemovirus (HMPV) is a respiratory virus that, while newly reported in the media, is not actually new or a pandemic threat. HMPV is a close relative of the respiratory syncytial virus and typically causes mild symptoms, similar to a common cold, particularly affecting those with weaker immune systems, such as young children and the elderly. By the age of five, about 8% of children have already been infected, indicating that the virus has been circulating for a long time, often undetected due to its similarities with other common viruses. The current focus on HMPV is amplified by a mix of media coverage, social media speculation, and the anniversary of COVID-19, which contributes to disproportionate concerns among the public.
