Early childhood emergency rash is a rash disease caused by human herpesvirus type 6. The virus is often latent in the throat and salivary glands of adults, and infection often occurs through adult kissing of children with an incubation period of 10 to 14 days. The incubation period is 10 to 14 days. It most often occurs in infants and children in the first 1.5 years of life. It usually occurs in children 6 months of age, with a sudden fever for the first time after birth, with a temperature of 38 to 39 degrees, a good mental state, a fever lasting 3 to 4 days, a temperature that drops to normal, and a rash the size of a grain of rice on the chest, abdomen and back of the face. When parents take their children to the hospital, it is best to tell the doctor who sees them that it is the first time the child has a fever, so an experienced doctor will be able to pay attention to it, thus avoiding unnecessary repeated visits to the hospital with the child and even intravenous fluids. If you have a fever, you should drink more water, take some antipyretic medicine if your body temperature reaches 38 degrees or more, and give warm water baths, the fever will subside and the rash will come out, and the rash will not need special treatment, and it will generally heal in about a week. The rash is not measles.
