Hand, foot and mouth disease is a viral infectious disease that occurs in infants and children. It is mainly characterized by the appearance of rashes or vesicle-like particles on the hands, feet and mouth, and generally recovers within a week with timely treatment.

In addition, parents also need to take precautions on a daily basis to prevent their children from being affected by this disease. Personal precautions: 1. Wash children’s hands with soap or hand sanitizer before and after meals and after going out, do not let children drink raw water or eat cold food, and avoid contact with sick children. 2.
