Why does a child have blisters on his body when he has a fever?

Children's physical fitness is far from being comparable to that of adults, so their own antiviral ability is also very poor. If you don't pay attention, you may catch a cold and have a fever. Some children have a lot of blisters on their bodies when they have a fever. This situation makes parents very scared. It is best to send them to a regular hospital for treatment in time. So what's the matter with blisters on children with fever?

First, why do children develop blisters on their bodies when they have a fever? If the baby also develops blisters on his mouth when he has a fever, it may be because of herpes that appears in the mouth during the fever. Some patients develop herpes one day after the fever, especially when the fever reaches 39℃ or 40℃, herpes is more likely to occur.

Second, herpes is a special type of upper respiratory tract infection. The early symptoms are generally not much different from those of a cold. Therefore, it is often misunderstood as a common cold and delayed in treatment. Many parents even mistakenly believe that their children have oral ulcers caused by getting a fever. Little do they know that long-term delay in treatment will eventually lead to the virus not being suppressed and developing into foot-and-mouth disease. Therefore, once a child has a fever, be sure to pay attention to whether the baby has blisters in the mouth. Parents need to pay special attention when the child has mouth pain. Parents need to pay more attention if the child is unable to express himself and shows symptoms such as crying, refusing to eat, and drooling.

Third, the virus of herpes and hand, foot and mouth disease may be the same. The pathogenesis of the two diseases is similar, but they are different manifestations in different stages. The only difference is that herpes occurs in the patient's mouth, while hand, foot and mouth disease occurs in the mouth, feet and buttocks. The high incidence of herpes is related to high temperatures, and it is easy to spread in hot and humid weather. Therefore, parents must pay attention to the physical health of their children in summer.

What happens when a child develops blisters on his body when he has a fever? Through the detailed introduction above, many parents should have a better understanding. Therefore, if a child develops blisters on his mouth after having a fever, it may be because he has herpes. So when the condition is unclear, remember not to use medication blindly. You should take your child to the hospital for relevant examinations in time, and then use targeted medications based on the cause of the disease to help your baby recover faster.
