Croup itself is not contagious, but the viruses that cause it, such as the parainfluenza virus, are contagious. These viruses can spread through respiratory droplets when an infected person coughs or sneezes. While croup can result from these infections, not everyone who contracts the virus will develop croup. Good hygiene practices can help reduce the spread of the viruses that lead to croup.
