Can an adult carry the croup virus and pass it along to a young child?

Croup is a respiratory infection caused by the parainfluenza virus, which is spread through close contact with an infected person. Adults can carry the parainfluenza virus and pass it along to young children, particularly those under the age of 5, who are most susceptible to infection. Transmission typically occurs through coughing, sneezing, or sharing food and drinks with an infected person. It's important to practice good hygiene, including frequent handwashing, to prevent the spread of the virus.
