HMPV vs Covid-19: Understanding the key differences and dangers

The human metapneumovirus (hMPV) is a common respiratory virus that typically causes mild cold-like symptoms. Studies show it has circulated in human populations since the 1970s, though it was first identified by scientists in 2001.

The virus accounts for 4-16% of acute respiratory infections globally, with cases usually peaking between November and May. While most adults have developed immunity through previous exposure, hMPV can cause more severe symptoms in infants encountering it for the first time and in people with weakened immune systems.

In an interview with HT Lifestyle, Dr Sangeeta V Budur, Consultant - Paediatrics and Paediatric Intensive Care at Aster RV Hospital, shared, “It is known to cause a range of illnesses from mild upper respiratory infections to severe pneumonia , bronchiolitis and acute respiratory distress syndrome. About 5 to 25% of the acute pediatric lower respiratory tract infections are associated with HMPV. The viral outbreaks peak in winter and spring season in northern hemisphere and June and July in southern hemisphere.”
