This is also one of the typical summer colds. Because it is easy to infect, it is often popular in nurseries. At the time of onset, there will be no rash on the body surface, but edema, ulcer and high fever will appear at the small tongue of the throat. Sometimes the body temperature can reach above 40 degrees. When the throat is stimulated, it will vomit, and the mood is very bad. But it usually takes only three or four days to cure. This cold, like hand-foot-mouth syndrome, is infected with Coxsackie virus.
