When there is herpes in the throat of children with recurrent fever symptoms, the first consideration is herpes pharyngitis, which is caused by a viral infection, and there is no specific medication, but more symptomatic treatment. Since this herpes will soon break on its own and leave ulcers on the surface of the throat, it is important to keep the throat itself clean and dry, pay attention to rinsing the mouth to maintain oral hygiene, and you can also use a local spray to relieve the painful sensation in the throat. For recurrent fever caused by viral infection, it is more likely that cooling medications, such as ibuprofen, are used when the body temperature exceeds 38.5 degrees, usually no more than four times a day. It can be supplemented with appropriate amount of physical cooling, such as using warm towels to wipe the palms of hands, feet, armpits and other parts of the body. Generally, fever caused by viral infection will recover significantly in 7-10 days. If accompanied by obvious systemic symptoms, such as abdominal pain, diarrhea, nausea and vomiting, attention must be paid to appropriate rehydration to maintain electrolyte balance and avoid further aggravation of symptoms.
