Chickenpox

Chickenpox blisters are usually less than a quarter of an inch wide, have a reddish base, and appear in bouts over 2 to 4 days. The rash may be more extensive or severe in kids who have skin disorders such as eczema. Some children have a fever, abdominal pain, sore throat, headache, or a vague sick feeling a day or 2 before the rash appears. These symptoms may last for a few days, and fever stays in the range of 37.7°–38.8° Celsius, though in rare cases may be higher. Younger children often have milder symptoms and fewer blisters than older children or adults. Calamine lotion may be applied to soothe the often severe itching. Cool baths may also help. The most infectious period is from two or three days before the rash appears and up to five days after this date. Children may return to school seven days after the outbreak of the most recent crop of spots.
