Chickenpox’s Causes and Risk Factors

A kid with chickenpox will be covered in pox in the typical condition or scenario, he must be out of school for at least a week. During the first three days, the kid with chickenpox will feel really miserable because of intense itching. The rest of the week is really bad time of boredom for staying in the house during a long time. The classic chicken-pox is much less common, as mentioned in the introduction of chickenpox vaccines.

This is a contagious disease that can be spread easily from this person to another.  Touching the fluids of a checkenpox blister, standing around a person with chickenpox when he is  coughing or sneezing will make you get this disease quickly. The chickenpox vaccine is able to prevent this disease completely but sometimes it just make the illness much milder. But remember that even this mild illness is contagious.

The pox will appear around 10-21 days after someone was infected. It can be contagious in 2 days before the pox broke out. Even when the blisters have crusts, it is still contagious.

Most cases of chickenpox are kid of 10 years old and younger. In general, it is rather mild, the serious cases rarely occur. In fact, the younger children are often healthier than older children and adults.

If a child has received chicken-pox vaccine or has mother who have had chicken pox, he will not catch this disease during the time one year after they were born. This is caused by the antibodies of their mother’s blood which are able to protect them. If he get this disease, it will be very mild. On the contrary,  a child under one year old who has not either chicken-pox vaccine and mother who has ever had chickenpox wil face the risk of severe chickenpox.

Like other kind of human disease, chickenpox will be severse in person whose immune system works not well. The immune system of human is often affected negatively by medicines ( steroids, chemotherapy) or many illness.
