Human metapneumovirus (hMPV) was discovered in 2001, and has been shown to cause respiratory illness in patients of all ages, but mostly in young children, the elderly, and the immunocompromised. hMPV is one of the leading causes of bronchiolitis in infants, but also causes pneumonia, asthma problems, and croup (a type of cough). Healthy people infected with hMPV usually have mild symptoms, but some people may have complications that require hospital admission. Some studies suggest that all children are infected at least once by the age of 5. However, recent studies have shown that older persons or those with weakened immune systems may be at risk for more severe disease. Infections will likely occur throughout the lifetime and are usually mild with little to no symptoms in healthy people.
What are the symptoms of RSV?
Healthy people infected with hMPV usually have mild symptoms, but some people may develop more severe disease conditions.
Symptoms of mild disease:
- Cough
- Runny/stuffy nose
- Sore throat
- Fever
- Shortness of breath
Symptoms of severe disease:
- Pneumonia
- Bronchiolitis
- Asthma problems
How long do symptoms last?
Symptoms of hMPV usually start 3-6 days after being exposed to the disease.
How do I know if I have hMPV?
See your health care provider. Limited testing is available through lab testing.
Spread of disease is likely to occur by direct contact either through sneezing or coughing or by touching surfaces or objects hMPV virus is on. Infection can occur when the virus contacts the eyes, mouth, or nose. The disease usually spreads more commonly during winter and spring.
Treatment includes fever reducers, hydration, and oxygen, if necessary.
Frequent and good hand washing, especially if you are ill or caring for others who are ill is important in preventing hMPV. Cough or sneeze into your upper sleeve, and discard used tissues promptly.
