Pediatric herpetic stomatitis is caused by herpes simplex virus infection, so the general course of the disease is 1-2 weeks. It is important to keep the mouth clean, drink plenty of water, eat slightly cool or cool fluids, avoid irritating foods, apply herpes net locally to inhibit the virus, and also spray watermelon cream, tin type dispersion, etc. To prevent infection, you can apply 2.5%-5% aureomycin cod liver oil, and for severe pain, you can apply 2% lidocaine locally before meals. Antibiotics do not shorten the course of herpetic stomatitis and are only indicated for babies with secondary infections. The lymph nodes involved in herpetic stomatitis are often swollen and painful, and usually last for 2-3 weeks.
