Dengue fever is mainly transmitted by mosquitoes. Dengue fever is an acute infectious disease caused by the dengue virus and is among the most widely spread mosquito-borne infections worldwide. Patients can develop clinical symptoms, including fever, rash, headache, muscle and joint pain, 1-14 days after infection, mostly after 5-9 days. In a small number of patients, the disease can deteriorate further and life-threatening dengue hemorrhagic fever, or dengue shock syndrome, occurs, resulting in severe shock and bleeding, and death can occur within 1-2 days due to hemorrhagic shock or central respiratory failure. Dengue fever is mainly treated symptomatically, and the prognosis is relatively good with reasonable treatment, and the mortality rate of dengue fever is about 1%-5%.
