What is Dengue fever (DF)?

Dengue infection is caused by a virus. It occurs commonly as dengue fever. Occasionally the patient suffering from dengue may develop bleeding. Common sites for bleeding are nose, gums or skin. Sometimes, the patient may have coffee ground vomiting or black stools. This indicates bleeding in gastro intestinal tracts and it is serious. The patient with dengue who has bleeding has dengue haemorrhagic fever (DHF ). Rarely the patient suffering from dengue may develop shock, then it is called dengue shock syndrome ( DSS).

What is the difference between suspected and probable case of dengue?

If a patient suspected to be having dengue has reduced platelets or an increase in blood haematocrit, then the patient has probable dengue. These additional findings makesdengue more likely. Patients with dengue may not have a high haematocrit if the person was anaemic to start with.

(Platelets are cells in blood that help to stop bleeding. Haematocrit indicates the thickness of blood).
