The treatment of DF and DHF is essentially supportive. Antipyretics as well as fluid resuscitation, monitoring, and support are often necessary. Monitoring of laboratory parameters and replenishment with blood products as necessary are indicated in severe cases of DHF. The World Health Organization has created a useful guide (Dengue Haemorrhagic Fever: Diagnosis, Treatment, Prevention and Control; available at the WHO Website) that delineates recommended approaches to the identification and management of DHF patients.
