The rash of HFMD is a typical manifestation of HFMD. It should be noted that the amount of HFMD rash is not proportional to the severity of the disease, so the more rashes do not mean that the disease is more serious. In the process of hand, foot and mouth disease, if there are more and more herpes, you need to keep the child’s skin, clothing, bedding clean and dry, cut the child’s nails; smaller infants should wrap their hands if necessary to avoid scratching the skin, causing breakouts and even infection. Children who have already developed ulcers and septic infections should be seen in a timely manner for further treatment. During the course of HFMD, in addition to the treatment of herpes, it is important to pay close attention to the temperature of the child. If the child has a high fever that does not subside, nausea, vomiting, shaking limbs, bad spirits, upturned eyes and flowering limbs, it is important to seek medical attention in a timely manner.
