It usually takes about 2 weeks to cure typical dengue fever and about 1 week to cure mild dengue fever. The treatment of typical dengue fever requires an acute fever phase, a polar phase and a recovery phase. The acute fever period usually lasts 2-7 days, the polar phase occurs 3-8 days after the onset of the disease, and the recovery period is 2-3 days after the polar phase. People infected with dengue virus often show symptoms such as persistent high fever, bone pain and general malaise. In addition, special attention should be paid to the fact that individual patients may not develop symptoms immediately and severe dengue fever may even lead to death. At present, there are no effective therapeutic drugs for dengue virus and mainly supportive symptomatic treatment measures are taken. In addition, since dengue virus can be transmitted through mosquito bites, it is important to pay attention to hygiene in daily life and to take anti-mosquito measures. Patients with dengue fever should be properly hydrated, eat more food rich in protein and vitamins, and do a good job of home hygiene and cleanliness.
