Itchy rash. First, raised red or pink bumps (papules) appear, resembling insect bites. They later become fluid-filled blisters (vesicles) and eventually crust over. New bumps continue to appear for several days. The face, scalp, chest, and back are common sites but the rash can appear anywhere over the body and can even enter the eyes, throat, and vagina.
Other chicken pox symptoms that precede or accompany the rash include fever, headache, fatigue, irritability, loss of appetite, and a dry cough.
In healthy children, chicken pox is generally mild and usually lasts 5-10 days. Chicken pox symptoms can be more serious in infants, older children, and those with weak immune systems.
Once infected, the varicella virus normally lies dormant in the body for the rest of one's life. The recurrence of chicken pox is unlikely but it can later cause shingles in adults.
