Four types of human parainfluenza viruses (HPIV) cause different symptoms. Respiratory secretions are easy to spread and are most common in children under 5 years of age. Recurrent infections are common, although usually less severe. Infected droplets released into the air during sneezing or cough also contribute to the spread of this disease. The virus can remain active in the air for up to an hour and on the surface for several hours. HPIV-1 and HPIV-2 usually lead to signs of Zákup, such as barking cough. HPIV-3 often causes symptoms of lower respiratory disease bronchiolitis and pneumonia. Other symptoms of parainfluenza include cold, sore throat, fever and irritability.
