EBVs are herpes viruses. A small number of children can heal on their own, and most children can be cured by treatment, but EBVs may be present in the body and cannot be completely eliminated. The EBV itself is self-healing, so asymptomatic children can be treated without intervention, but some children may experience symptoms similar to upper respiratory tract infections, such as sore throat, vomiting, diarrhea, and loss of appetite, as well as systemic symptoms such as fever, rash, and swollen lymph nodes. However, some children may develop symptoms similar to upper respiratory tract infection such as sore throat, vomiting, diarrhea, loss of appetite, and systemic symptoms such as fever, rash, and swollen lymph nodes. Symptoms usually do not resolve on their own and require systemic antiviral therapy to improve and eliminate clinical symptoms. Since EBV is considered to be one of the potentially cancer-causing human tumor viruses, children who develop cancer should be treated as soon as possible for complications such as nasopharyngeal carcinoma, lymphoma, and infectious mononucleosis under the guidance of a physician. Generally, after the child has recovered and immune function has gradually returned to normal, attention should be paid to good personal hygiene habits, strengthening physical exercise, and regular medical checkups to prevent recurrence.
