Chickenpox is caused by a virus called varicella zostervaricella zoster. People who get the virus often develop a rash of spots that look like blisters all over their bodies. The blisters are small and sit on an area of red skin that can be anywhere in the body .Chickenpox are itchy. The illness also may come along with a runny nose and cough. Thanks to the chickenpox vaccine, lots of kids don't get chickenpox at all. Kids who do get it, if they got the shot, often get less severe cases, which means they get better quicker.
At first, the rash looks like pinkish dots that quickly develop a small blister on top (a blister is a bump on your skin that fills up with fluid). After about 24 to 48 hours, the fluid in the blisters gets cloudy and the blisters begin to crust over, then a new group of spots may appear. New chickenpox usually stop appearing by the seventh day, though they may stop as early as the third day. It usually takes 10β14 days for all the blisters to be scabbed over and then you are no longer contagious
How Does Chickenpox Spread?Chickenpox is contagiouscontagious,it can easily spread to someone else. Someone who has chickenpox is most contagious during the first 2 to 5 days that he or she is sick. That's usually about 1 to 2 days before the rash shows up. So you could be spreading around chickenpox without even knowing it!
A person who has chickenpox can pass it to someone else by coughing or sneezing. When he or she coughs, sneezes, laughs, and even talks, tiny drops come out of the mouth and nose. These drops are full of the chickenpox virus.
Tips can help you feel less itchy:
Keep cool because heat and sweat will make you itch more. You might want to put a cool, wet washcloth on the really bad areas.
Soak in a lukewarm bath. Adding some oatmeal .Oatmeal to your bath water can help relieve the itching.
Don't Scratch
Scratching the blisters can tear your skin and leave scars. Scratching can also let germs in, and the blisters could get infected. While you have the chickenpox, Do not take aspirin because it can cause a rare but serious illness in kids called Reye syndrome . Sometimes, chickenpox leads to other, more serious illnesses.Usually, you won't have any major problems and you'll get better in a week or two. And when all the blisters have scabs, you're not contagious anymore and you can go back to school! In a few days, the scabs will fall off. And once you've had chickenpox, it's unlikely you'll ever get it again.
