Hosts
Humans and animals.
Transmission / Exposure Route
It usually spreads from an infected person to another through the air by coughing, personal contact, and touching objects or surfaces that are contaminated.
Case Fatality Ratio
Mortality due to the parainfluenza virus is very rare. Whenever it does occur, it is normally in the three main risk groups: very young, elderly, and immunocompromised. In developing countries, the highest mortality rate is seen in preschool students, HPIVs causing 10% of the deaths of preschool students.
Incubation Period
It has an incubation period of 2 to 6 days.
Microbiology
Parainfluenza viruses are RNA viruses that are 150-250 nm in size.
Enviromental Survival
Parainfluenza viruses’ most optimal ph is around 7.4 to 8. The optimal temperature is higher, above 37 degrees Celsius.
