PATHOLOGY

Detailed explanation-1: -Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV).

Detailed explanation-2: -Some people who have been vaccinated against chickenpox can still get the disease, called breakthrough chickenpox. However, they usually have milder symptoms with fewer or no blisters (or just red spots), a mild or no fever, and are sick for a shorter period of time than people who are not vaccinated.

Detailed explanation-3: -How is chickenpox spread? Chickenpox spreads very easily by touching chickenpox blisters or through the air when someone with chickenpox coughs or sneezes. The virus does not live long on surfaces.

Detailed explanation-4: -The best way to prevent chickenpox is to get the chickenpox vaccine. Everyone-including children, adolescents, and adults-should get two doses of chickenpox vaccine if they have never had chickenpox or were never vaccinated. Chickenpox vaccine is very safe and effective at preventing the disease.
