Symptoms of Chickenpox
Symptoms usually occur 10-21 days after contact with the chickenpox virus. Initial symptoms include:
- General feeling of discomfort
- Loss of appetite
Within 1-2 days after the initial symptoms, a rash develops.
Characteristics of the rash include:
- At first, the rash consists of small, flat, red spots.
- The spots become raised and form clusters of round, itchy, fluid-filled blisters on a red base.
- New clusters form over 5-6 days.
- After the rash develops, there is usually a variety of spots visible: flat red areas, blisters with clear fluid, blisters with cloudy fluid, and open blisters.
- The rash usually develops on the skin above the waist, including the scalp.
Exposed areas are often most affected.
- The rash may sometimes appear on the inside of the eyelids, in the mouth, nose, throat, upper airway, voice box, rectum, or vagina.
In healthy children, the rash usually crusts over by day 6-7. The crusts are gone within three weeks, usually without scarring.
Adults or patients who are immunocompromised may have more severe cases that last longer.
