Chickenpox is caused by a viral infection. This disease is quite contagious and is mostly transmitted through the air and respiratory system. The contagious period generally lasts about ten days, but it can vary from person to person, with some patients possibly experiencing a longer duration. Generally, children exhibit milder symptoms and have a shorter treatment period. In adults, the treatment period tends to be longer, typically ending when the symptoms have subsided and the blisters on the body have completely dried and fallen off. Once this disease is contracted, it is essential to isolate and treat it properly using antiviral medications. Children and elderly individuals in the household should avoid frequent contact to prevent transmission. After the onset of chickenpox, high fever may occur, so it is necessary to have some fever-reducing medications on hand to prevent other illnesses caused by the fever.
