Hand, foot and mouth disease is mainly an acute infectious disease caused by enterovirus infections, of which the most common viruses are enterovirus 71 and coxsackievirus A16, of which the main clinical manifestations are skin rashes on the hands, feet and buttocks and oral herpes. Among them, oral herpes can cause pain, food refusal and salivation in children. In this case, you can give your child buspirone anti-inflammatory oral solution, and you can also buy open-throat sword spray to spray the throat, which is very effective in relieving pain. Normally, spraying once every two hours for about 1-2 days can effectively relieve the pain situation. All children will eat and there will be no obvious resistance to eating. If other systems are involved, such as the nervous system, respiratory system and circulatory system, it is a high priority and usually requires hospitalization for aggressive treatment.
