human metapneumovirus symptoms in adults
How is human metapneumovirus transmitted? Spread of the virus is most likely to occur by direct or close contact with the respiratory secretions of infected persons or by contact with objects and surfaces contaminated by their secretions. Most persons with hMPV infection have mild symptoms including cough, runny nose or nasal congestion, sore throat and fever. More severe illness, with wheezing, difficulty breathing, hoarseness, cough, pneumonia, and in adults, aggravation of asthma, also has been reported. In children younger than 1 year of age, the elderly and persons who have weak immune systems, hMPV can cause more serious respiratory illness.
