How to Prevent and Fight Dengue Fever

As the coronavirus pandemic currently grips the world, everyone is concerned about how to prevent the virus from spreading and revitalise the economy from recession at the same time. However, the current crisis lurking in Singapore is not just the coronavirus epidemic, but another threatening one, dengue fever. The number of cases in Singapore in July this year is five times that of the same period last year. The total cumulative cases have reached 26,300 so far this year.

Dengue fever is an illness caused by the dengue virus, which is carried and spread by the Aedes mosquitoes. It can be roughly divided into two categories: one is dengue hemorrhagic fever, and the other is dengue shock syndrome.

Although dengue fever death is rare, its symptoms, such as fever, cough, headache, vomiting, abdominal pain, orbital pain, muscle, and joint pain, etc., are severe or even to the extent of shock, so they cannot be underestimated.

At present, there is no drug that can treat this disease. The treatment depends to a large extent on controlling symptoms and avoiding the occurrence of serious complications and the reduction of platelets.

Traditional Chinese medicine refers to dengue fever (commonly known as mosquito disease) as “Dengue fever”, which belongs to the category of “febrile disease”. At different stages of its onset, there are corresponding prescriptions for symptomatic treatment. In Traditional Chinese medicine treatment, it is divided into 4 stages of diagnosis and treatment periods.
