Hand, foot, and mouth disease is a common contagious exanthematous disease in pediatrics, caused by a viral infection with a certain epidemic nature. Its main modes of transmission include respiratory, digestive tracts, and close contact. During the epidemic, usually in the summer and autumn seasons, it is recommended that parents avoid taking children to public places. If a suspected case is found, timely isolation should be carried out, and close contacts should be quarantined for 7-10 days. Additionally, it's important to maintain good personal hygiene, such as washing hands before eating and after using the toilet, and to keep indoor ventilation in the home. If a child has been in contact with an infection or a suspected case of hand, foot, and mouth disease, it is crucial to monitor the child for any discomfort and check their temperature regularly. If the child feels unwell, take them to the hospital for treatment promptly.
