Chickenpox (Varicella)

Each year, millions of children around the world are affected by chickenpox, or varicella, a highly contagious viral infection caused by the varicella-zoster virus. It spreads easily through coughing, sneezing, or direct contact with the fluid from blisters. The illness is marked by an itchy, blister-like rash, often accompanied by fever, fatigue, and loss of appetite.

Chickenpox typically begins with mild symptoms such as low-grade fever and general discomfort, followed by the appearance of small red spots that turn into fluid filled blisters. These blisters eventually scab over after several days, but new ones may continue to form for up to a week. While most cases are mild, complications such as skin infections, pneumonia, or brain inflammation can occur, especially in infants, teens, and those with weakened immune systems.

Prevention through vaccination is the most effective protection. Since its introduction in the 1990s, the varicella vaccine has significantly reduced both the number and severity of cases. According to the CDC, two doses provide about 90% protection.

Treatment focuses on relieving symptoms and preventing infection. Acetaminophen can help reduce fever, while calamine lotion, oatmeal baths, and antihistamines ease itching. Children should avoid scratching to prevent scarring, and aspirin should never be used due to the risk of Reye’s syndrome. In more serious cases, doctors may prescribe antiviral medication to shorten the illness.

Though often mild, chickenpox can be uncomfortable and disruptive. With vaccination, proper care, and awareness, children can recover safely and avoid serious complications.
