Blisters can also arise inside the mouth.<\/p>\n<p>The spread pattern may vary from child to child. There may be only one dispersion of vesicles, or the entire body may be covered with up to 500 vesicles. The vesicles tend to be very itchy and uncomfortable.<\/p>\n<p>Some children may also experience additional symptoms such as high fever, headache, cold-like symptoms, vomiting, and diarrhea. <\/p>\n<p>Chickenpox is usually more severe in adults and can be fatal in complicated cases. Most adults who have experience with chickenpox <span class=\"term\" data-term-id=\"590\">prodromal<\/span> symptoms for up to 48 hours before erupting into the rash. These include fever, <span class=\"term\" data-term-id=\"1211\">discomfort<\/span>, headache, loss of appetite and abdominal pain.

Adults with chickenpox who work among children should also stay home.<\/p>\n<p>It may take 10 to 21 days after contact with an infected person for someone to develop chickenpox. This is the time it takes for the virus to replicate and erupt in the characteristic rash on the new <span class=\"term\" data-term-id=\"1313\">host<\/span>.<\/p>\n<p>Because chickenpox can cause complications in immunocompromised individuals and pregnant women, these people should avoid visiting friends or family when a case of chickenpox is known.
