How to treat dengue fever
At present, there is no specific antiviral drug for the treatment of dengue fever, and timely medical treatment, early diagnosis, and early symptomatic treatment can reduce the risk of exacerbation of the disease.
After the onset of the disease, it is necessary to pay attention to rest and pay attention to mosquito prevention and isolation (using screen doors and windows and mosquito nets).
Fever reduction is mainly based on physical cooling.
Once symptoms such as severe abdominal pain, persistent vomiting, red spots on the skin, bleeding from the mouth and nose, hematemesis and blood in the stool, drowsiness and irritability, clammy skin, and difficulty breathing, indicate the need for emergency care, and you should immediately return to the outpatient clinic or emergency department.
Patients with dengue fever generally have a good prognosis and can basically recover after timely treatment, but there are also a few reports of deaths in severe cases.
