Human parainfluenza viruses (HPIVs) commonly cause respiratory illnesses in infants and young children. But, anyone can get HPIV illness. Symptoms may include fever, runny nose, and cough. Patients usually recover on their own. However, HPIVs can also cause more severe illness, such as croup or pneumonia...
HPIVs Are Not the Same as Influenza (Flu) Viruses
- People usually get HPIV infections in the spring, summer, and fall. Flu is more common in the winter.
- Flu vaccine will not protect you against HPIV illness.
How HPIVs Spread
HPIVs spread from person to person through—
- the air by coughing and sneezing,
- close personal contact, such as touching or shaking hands, and
- touching objects or surfaces with the viruses on them then touching your mouth, nose, or eyes.
