Despite being discovered more than 20 years ago, many people still consider it one of the unknown viruses. It is the human metapneumovirus known as HMPV.

This is a respiratory virus from the Pneumoviridae family, like the respiratory syncytial virus (RSV), and can affect any population, although it is more dangerous in children, the elderly and those with comorbidities.

According to data from the US Centers for Disease Control and Prevention (CDC), there will be an increase in the number of cases of up to 36% in 2023 compared to previous years.

How to distinguish the coronavirus from other viruses such as respiratory syncytial and flu

Despite being discovered in 2001, this virus has been circulating since the 1950s.

He New York Post reported that cases peaked in March and April, although they declined in May due to warming weather.

One of the causes that can influence its spread is the decrease in people’s immunity after the measures used during COVID-19, which correspond to the use of masks and social distancing.

Among the symptoms that occur are cough, fever, congestion and runny nose, sore throat and shortness of breath.

Pediatrics professor John V. Williams noted that this is the “most important virus you’ve never heard of.”

A blood test can help you determine if you have the virus, there is still no vaccine against the disease, and treatment allows you to overcome the symptoms.
