| Chickenpox Chickenpox is an infection with a blistering rash, which is caused by the Varicella virus. This virus also causes shingles Course and Symptoms The incubation period, the length of time from exposure to the virus to developing the condition, is two to three weeks. If someone in the house has chickenpox, the likelihood of someone else in the house catching it, who has not already had it, is as much as 90% ie 9 out of 10. It usually affects children and starts with a slightly raised temperature, and feeling under the weather, along with the development of red spots, mainly on the body and face. The spots appear over a few days and progress from being red spots to forming blisters which eventually burst, dry and crust, ultimately to heal. The spots are very itchy and if the child scratches, and infects them they will leave scars. |
