The so-called chickenpox is caused by the herpes zoster virus infection. It is generally recognized that the symptoms of chickenpox are most severe within 3-4 days after the onset of the disease, with a large number of blisters appearing, along with symptoms such as a more intense and pronounced fever, and that the symptoms of chickenpox may also be related to the body’s resistance and whether or not care measures are in place. Symptoms may continue to worsen in some people on the 2nd-3rd day after the onset of the disease, and in some people they may continue to worsen after 3-4 days. Most chickenpox treatments must be done in a timely manner in a hospital, and it is important to stick to a light diet to prevent eating overly stimulating foods.
