Varicella-Zoster Virus (Chickenpox)

Varicella-Zoster Virus (VZV) causes chickenpox, a highly contagious infection characterized by an itchy, blister-like rash that spreads across the body. It primarily affects children but can occur at any age. After the initial illness, the virus remains dormant in nerve cells and can reactivate later in life as shingles. Chickenpox spreads through respiratory droplets from coughs and sneezes or contact with the rash. Symptoms include fever, tiredness, and skin lesions. Vaccination greatly reduces the risk of illness and complications. Most people recover fully with supportive care, but the virus can pose higher risks for pregnant women, newborns, and immunocompromised individuals.
