Is Parainfluenza Contagious?
Transmission of Parainfluenza from Person to Person
Parainfluenza is considered to be contagious between people.
Generally the infectious agent may be transmitted by saliva, air, cough, fecal-oral route,
surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc.
Parainfluenza, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
The contagious disease, Parainfluenza, can be transmitted:
- from person to person by saliva, air, coughing, contact, surfaces, fecal-oral route, etc.
HPIVs are spread from respiratory secretions through close
contact with infected persons or contact with contaminated surfaces or
objects. Infection can occur when infectious material contacts mucous
membranes of the eyes, mouth, or nose, and possibly through the inhalation
of droplets generated by a sneeze or cough. HPIVs can remain infectious
in aerosols for over an hour. (Source: excerpt from Human Parainfluenza Viruses: DVRD)
About contagion and contagiousness:
Contagion and contagiousness refers to how easily
the spread of Parainfluenza is possible from one person to another.
Other words for contagion include "infection", "infectiousness",
"transmission" or "transmissability".
Contagiousness has nothing to do with genetics
or inheriting diseases from parents.
