Prevention: Get measles virus and vaccinations on time.

4. Chickenpox: Chickenpox is a highly contagious childhood rash disease that mostly occurs in winter and spring. Spread through direct contact, droplets, and air. 90% of children with the disease are <10 years old, and about 90% to 96% of susceptible contacts will develop the disease. The virus disappears after the chickenpox scabs, so the infectious period is from 24 hours before the visit to the scabs on the lesions, which is about 7 to 8 days. The incubation period is 10 to 21 days, usually about two weeks. The causative agent of chickenpox is varicella-zoster virus (VZV), human herpesvirus type 3.
