Chickenpox is primarily classified as a viral infection caused by the varicella-zoster virus (VZV). It is characterized by an itchy rash, fever, and flu-like symptoms. Additionally, chickenpox is considered a contagious disease, as it can easily spread from person to person through respiratory droplets or direct contact with the rash. Vaccination has significantly reduced the incidence of chickenpox in many regions.
Chickenpox is caused by the varicella-zoster virus, and it can spread easily. You can get chickenpox from an infected person who sneezes, coughs, or shares food with you. It is also spread if you touch the fluid from a chickenpox blister. A person who has chickenpox can spread the virus even before he or she has any symptoms. Chickenpox is most easily spread from 2 to 3 days before the rash appears until all the blisters have crusted over.
