Five years after the first cases of COVID-19, reports of hMPV, an obscure respiratory virus in China may understandably raise concerns.

The human metapneumovirus is reportedly surging in China, but should Americans be concerned? Here's what to know about HMPV symptoms and more.

While cases are climbing in China, the situation is very different from what it was when Covid-19 emerged five years ago, medical experts say. HMPV has circulated in humans for decades.

The WHO said Chinese data up to Dec 29 showed detections of HMPV, seasonal influenza, rhinovirus, and respiratory syncytial virus (RSV) have all increased in recent weeks, particularly in northern parts of China. Influenza is currently the most commonly reported cause of disease, it said.

As cases of the HMPV virus continue to increase in the U.S. and in China, here's what you need to know about the virus.

A leading GP has reassured Britons that there is no cause for alarm over the human metapneumovirus (HMPV) outbreak, despite recent concerns. Speaking to GB News, Dr Renee Hoenderkamp explained that HMPV has been "circulating for at least 15 years" and is similar to "a common cold".
