Chickenpox – Overview
Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus (VZV). Most commonly seen in children, it presents as an itchy, blister-like rash that usually spreads across the face, chest, and back, before affecting the rest of the body. While it is generally mild in healthy children, chickenpox can cause serious complications in adults, infants, pregnant women, and people with weakened immune systems.
The infection typically starts with flu-like symptoms such as fever, fatigue, and loss of appetite, followed by the appearance of red spots that quickly turn into fluid-filled blisters. These blisters eventually burst, scab over, and heal within one to two weeks.
This condition spreads easily through respiratory droplets (coughing or sneezing), direct contact with an infected person, or touching items contaminated by the fluid from blisters. It is contagious from about 48 hours before the rash appears until all spots have crusted over.
Chickenpox
Although a single infection usually provides lifelong immunity, the virus remains dormant in the body and can reactivate years later as shingles, a painful rash that occurs along nerve lines.
Vaccination has significantly reduced the number of these cases worldwide. In countries where the varicella vaccine is routine, outbreaks are rare, and those infected typically experience a milder illness.
Chickenpox is uncomfortable but manageable for most people. Prompt diagnosis and supportive care help reduce symptoms and prevent complications.
