A.

Croup is contagious and is usually spread by airborne infectious droplets sneezed or coughed by infected children. When a healthy child inhales infectious droplets, symptoms can develop in two to three days. The infection can also be spread by infected mucus deposited on doors, furniture, toys, and other objects. A healthy child can become infected by accidentally touching the infectious mucus and transferring the infection into his/her mouth.
