There is no specific data on the probability of dengue fever recovering on its own, but the vast majority of dengue fever patients recover on their own. Dengue fever is an acute insect-borne infection caused by the dengue virus. It is self-limiting, and the majority of patients with typical and mild dengue fever have a good prognosis, recovering in 7 to 10 days. The case-fatality rate is only about 3 in 10,000, usually due to central respiratory failure in severe cases. There are no specific anti-dengue virus drugs. Typical symptoms of dengue fever are fever, rash, hemorrhage and other symptoms, generally take symptomatic supportive treatment, acute stage is recommended to bed rest, physical cooling is the main, light semi-liquid diet, at the same time, anti-mosquito quarantine until the fever symptoms are relieved. If the bleeding site is clear, stop bleeding locally as soon as possible. Those who are suspected to be infected with dengue fever need to consult regular infectious disease hospitals in time to avoid infecting other people or delaying the condition and causing adverse consequences.
