What is HMPV Virus?
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.
Though HMPV shares similarities with other respiratory viruses like RSV (Respiratory Syncytial Virus), measles, and mumps, it does not have a vaccine, and no antiviral treatments are available. Most people recover with rest and hydration, but in severe cases, hospitalization and supportive treatments like oxygen therapy may be necessary.
HMPV Virus symptoms
Human Metapneumovirus (HMPV) infections typically present with mild symptoms, including:
- Cough
- Runny nose or nasal congestion
- Sore throat
- Fever
However, in some cases, HMPV can lead to more severe illness, characterized by:
- Wheezing
- Difficulty breathing
- Hoarseness
- Pneumonia
- Aggravation of asthma in adults
In children younger than 1 year of age, the elderly and persons who have weak immune systems, hMPV can cause more serious respiratory illness.
Who is at risk?
While anyone can contract HMPV, the virus is most concerning for young children, the elderly, and individuals with compromised immune systems. Children under the age of five are particularly vulnerable, with about 5-16% of cases potentially progressing to lower respiratory tract infections like pneumonia. Elderly individuals and those with underlying health conditions may experience more severe symptoms as well.
Health experts have advised that while there is no immediate cause for panic, individuals at higher risk of complications should take precautions to avoid exposure to the virus, particularly during the peak winter and spring months.
