A surge in human metapneumovirus, or HMPV cases has been witnessed in China despite the Chinese government assurance that the situation is under control, Reuters has reported.

While the number of cases are on an upward spiral, health officials have stated that the outbreak is still within manageable scope and does not present a considerable threat of developing into a pandemic like COVID-19.

In the United States, records from the Centers for Disease Control and Prevention shows that HMPV cases have been on the rise since last November. As of December 28, 1.94% of weekly testing had returned positive for the virus.

According to the U.S. Centers for Disease Control and Prevention (CDC), the virus, which is related to respiratory syncytial virus (RSV), was first detected in 2001.

Here’s everything you need know about the virus and how to stay safe.

What is human metapneumovirus?

Human metapneumovirus (HMPV) is a virus that causes symptoms similar to the common cold. While it is largely responsible for upper respiratory infections, it can occasionally cause more significant lower respiratory difficulties such as pneumonia, asthma exacerbations, or worsening chronic obstructive pulmonary disease.

What Are the alarming Signs of HMPV You Need to Watch Out for?

Common symptoms of HMPV infection include:
• Cough.
• Fever.
• Nasal congestion.
• Difficulty breathing.

The typical incubation period for human metapneumovirus is between 3 to 6 days, and the duration of the illness can vary based on its severity, but it generally follows the same timeline as other viral respiratory infections.

Human Metapneumovirus Transmission and Prevention

HMPV spreads through direct contact with an infected person or by touching surfaces contaminated with the virus. In the U.S., the virus mostly spreads during the winter and spring seasons.
HMPV can be prevented by following some of the guidelines recommended by the CDC.
• Wash hands frequently with soap and water for at least 20 seconds.
• Avoid touching your eyes, nose, or mouth with unwashed hands.
• Steer clear of close contact with individuals who are sick.

Can the virus be treated?

At the moment, there is no specific antiviral treatment or vaccine for HMPV.
