Chickenpox, also known as varicella, is a highly contagious viral infection that is most commonly seen in children. It is caused by the varicella-zoster virus, which is a member of the herpes virus family. The main symptoms of chickenpox include an itchy rash that develops into blister-like lesions, fever, headache, and fatigue. The rash usually appears first on the chest and face, and then spreads to the rest of the body. The disease is usually mild in children, but can be more severe in adults, particularly those with weakened immune systems.
Chickenpox is spread through the air when an infected person coughs or sneezes, or by direct contact with the blisters. Once a person has had chickenpox, they usually develop immunity to the virus and will not get it again. However, the virus can remain dormant in the nervous system and may reactivate later in life as shingles. Vaccines are available to prevent chickenpox and are recommended for children, especially for those who are at high risk of severe disease.
