Chickenpox

Chicken Pox Chickenpox is a common illness among kids, particularly those under age 12. An itchy rash of spots that look like blisters can appear all over the body and be accompanied by flu-like symptoms. Symptoms usually go away without treatment, but because the infection is very contagious, an infected child should stay home and rest until the symptoms are gone. Chickenpox is caused by the varicella-zoster virus. Kids can be protected from VZV by getting the chickenpox vaccine, usually between the ages of 12 to 15 months. The Centers for Disease Control and Prevention also recommends a booster shot at 4 to 6 years old for further protection. The CDC also recommends that people 13 years of age and older who have never had chickenpox or received the chickenpox vaccine get two doses of the vaccine at least 28 days apart. A person usually has only one episode of chickenpox, but VZV can lie dormant within the body and cause a different type of skin eruption later in life called shingles. Getting the chickenpox vaccine significantly lowers kids' chances of getting chickenpox, but they might still develop shingles later in life.

Symptoms Chickenpox causes a red, itchy skin rash that usually appears first on the abdomen or back and face, and then spreads to almost everywhere else on the body, including the scalp, mouth, nose, ears, and genitals. The rash begins as multiple small red bumps that look like pimples or insect bites. They develop into thin-walled blisters filled with clear fluid, which becomes cloudy. The blister wall breaks, leaving open sores, which finally crust over to become dry, brown scabs. Chickenpox blisters are usually less than a quarter of an inch wide, have a reddish base, and appear in crops over 2 to 4 days. The rash may be more extensive or severe in kids who have skin disorders such as eczema. Some kids 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 100°–102° F, though in rare cases may be higher. Younger kids often have milder symptoms and fewer blisters than older children or adults. Chickenpox is usually a mild illness, but can affect some infants, teens, adults, and people with weak immune systems more severely. Some people can develop serious bacterial infections involving the skin, lungs, bones, joints, and the brain. Even kids with normal immune systems can occasionally develop complications, most commonly a skin infection near the blisters. Anyone who has had chickenpox (or the chickenpox vaccine) as a child is at risk for developing shingles later in life, and up to 20% do. After an infection, VZV can remain inactive in nerve cells near the spinal cord and reactivate later as shingles, which can cause tingling, itching, or pain followed by a rash with red bumps and blisters. Shingles is sometimes treated with antiviral drugs, steroids, and pain medications, and there's now a shingles vaccine for people 60 and older. Ckicken pox can be any size in between 1cm 2 a milimeter
