Chickenpox is a viral infection that causes fever and an itchy rash with spots all over the body. The rash caused by chickenpox appears 10 to 21 days after exposure to the varicella-zoster virus and often lasts about 5 to 10 days. The rash usually starts on the chest, back, and face, and then spreads over the entire body, including inside the mouth, eyelids, or genital area. The rash turns into itchy, fluid-filled blisters that eventually turn into scabs. Other typical symptoms that may begin to appear one to two days before the rash include:

• Fever
• Tiredness
• Loss of appetite
• Headache
• Stomach ache

Children usually miss 5 to 6 days of school or childcare due to chickenpox. Some people who get chickenpox may have more severe symptoms and may be at higher risk for complications, such as:

• Infected skin, soft tissues, bones, joints, or bloodstream caused by bacteria
• Encephalitis
• Pneumonia
• Becoming dehydrated
• Blood clotting or healing issues
• Liver problems

It is important to note that most people who have had chickenpox or have gotten the vaccine are immune to chickenpox. If youve been vaccinated and still get chickenpox, symptoms are often milder. You may have fewer blisters and mild or no fever.
