Emerging Respiratory Threat - Human Metapneumovirus (HMPV)

According to the Centers for Disease Control and Prevention (CDC), there was a notable increase in infections caused by human metapneumovirus (HMPV), an emerging threat.

Despite declining COVID-19 and respiratory syncytial virus (RSV) cases in the United States, the Centers for Disease Control and Prevention (CDC) reported a surge in infections caused by another respiratory virus known as human metapneumovirus //(HMPV).

The percentage of tests positive for HMPV surged to 17.5 percent for antigen tests and 9.6 percent for PCR tests at the end of March, Xinhua news agency reported citing the latest CDC data.

Future Viruses Could be Deadlier Than Covid-19: WHO
The WHO has issued a warning to nations globally, urging them to undertake necessary preparations for an impending pandemic that could be even deadlier than the coronavirus.

‘While COVID-19 and respiratory syncytial virus (RSV) cases were on the decline throughout the United States, the Centers for Disease Control and Prevention (CDC) observed an upward trend in infections attributed to human metapneumovirus (HMPV), another respiratory virus. #COVID-19, #respiratory syncytial virus, #infections, #respiratory virus ’

During the four years before the pandemic, the weekly percentage of HMPV positive tests never reached higher than 7.7 percent, the data revealed.

Unexpected Surges Amidst Pandemic Decline

Discovered in 2001, HMPV is in the Pneumoviridae family along with RSV.

Broader use of molecular diagnostic testing has increased identification and awareness of HMPV as an important cause of upper and lower respiratory infection, according to the CDC.

HMPV can cause upper and lower respiratory disease in people of all ages, especially among young children, older adults, and people with weakened immune systems.

COVID-19 Positive Donor Hearts Lower Survival in Transplant Patients
An analysis of data from donors suggests donor hearts from patients who were COVID-19 positive could place transplant patients at increased risk of mortality.

Surveillance data from CDC's National Respiratory and Enteric Virus Surveillance System shows HMPV to be most active during late winter and spring in temperate climates.

Symptoms commonly associated with HMPV include cough, fever, nasal congestion, and shortness of breath, according to information on the CDC website.
