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).

How can I prevent mosquito bites to prevent dengue?

Wednesday, 28 September 2011


There is no way to tell if a mosquito is carrying the dengue virus. Therefore, people must protect themselves from all mosquito bites.
Dengue mosquitoes bite during the day time throughout the day. Highest biting intensity is about 2 hours after sunrise and before sunset.
Wear full sleeves clothes and long dresses to cover as much of your body as possible.
Use repellents- be careful in using them in young children and old people.
Use mosquito coils and electric vapour mats during the daytime also to prevent dengue.
Use mosquito nets to protect children, old people and others who may rest during the day. The effectiveness of these nets can be improved by treating them with permethrin (pyrethroid insecticide). This bed-net is called Insecticide Treated Nets and are widely used in the prevention of malaria.
