Veda #57 : Chickenpox VS Cold

Day 57
"Why did we get chicken pox only once, but we might encounter cold or flu several times?"

Most of you probably had chicken pox when you was a little kid. If now you see any people got chicken pox, you're free from worries of having that disease again, because you know that it won't do you any harm again. why did that happen?it's just not like flu or cod that can strike us all over and over again.

Chickenpox is caused by a virus called varicella 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 from the size of a pencil eraser to the size of a dime.

When you get sick, your white blood cells fight the harmful germs with special germ killers called antibodies. White cells manufacture antibodies for each particular sickness, so if you have chicken pox, your white blood cells make chicken pox antibodies. After you are recovered, these antibodies stay in your blood and keep killing any chicken pox viruses that get into your body. That is why you can’t get chicken pox twice. You have become immune to it. You've probably heard that chickenpox are itchy. It's true. The illness also may come along with a runny nose and cough. But the good news is that chickenpox is a common illness for kids and most people get better by just resting like you do with a cold or the flu.

It's very rare case, but actually chicken pox will do harm to you twice, if the first one was happened too mild. That's why many eldest group their kids if one of them having a chicken pox, to infect all of them. Because having chicken pox on age 20 and more is considered dangerous and deadly. Most adults who get chickenpox are immunosuppressed meaning that their immune systems aren't functioning properly.

In the same way, when you get a cold from a cold virus, your body makes antibodies to fight that particular cold virus. You can never get a cold from that particular kind of virus again. However, since there are more than 200 different kinds of viruses that can cause colds, a new cold virus can enter your body and you will not have antibodies in your blood to fight it. Then you will get another cold.
