Dengue is a severe viral disease transmitted by the bite of the mosquito and caused by any of 4 dengue virus serotypes.
Den-1, Den-2, Den-3, Den-4
Dengue Fever is a severe flu like illness that affects infants, young children, and adults, but seldom causes death.
Dengue Heamorrhagic Fever (DHF) is a more severe form in which bleeding and sometimes shock occurs leading to death. It is most serious in children. Symptoms of bleeding usually occur after 3-5 days of fever.
Rapid replacement with fluid and electrolyte solution.
Plasma should be used for patients with severe cases of shock.
Blood transfusion for patients who have severe bleeding.
Avoid use of aspirin and ibuprofen because it can increase bleeding and cause stomach pain.
If one or more signs of DHF are seen, take the patient to the hospital immediately, give fluids to drink while transferring the patient to the hospital.
Dengue is spread by the bite of an infected mosquito, specifically Aedes Aegypti and Aedes Albopictus.
The mosquito gets the virus by biting and infected person.
The first symptoms of the disease occur about 5-7 days after an infected bite.
The virus enters the midgut, multiplies and spreads to other mosquito organs including the salivary glands. It takes 8-10 days to complete this process.
There is no way to tell if a mosquito is carrying the virus, therefore, people must protect themselves from all mosquito bites.
Where does the mosquito live?
The mosquito rests indoors in closets and other dark places.
Outside, the rest where it is cool and shaded.
The female mosquito lays her eggs in water containers in and around homes, schools, and other areas around towns or villages. These eggs become adults in about 10 days.
The larvae hatch from the mosquito eggs and survive in the water for around a week. Then, they become a pupa stage for one or two days, after which the adult mosquito emerges ready to bite.
Where does the mosquito breed?
Dengue mosquitoes breed in stored, exposed water collections.
Favored breeding places are: barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, discarded bottles, tins, tires, water coolers, etc. And any place where rain water collects or is stored.
Prevention of Dengue
Eliminate the mosquitoes and their breeding places.
Prevent mosquito bites

wearing full sleeved clothes and long dresses to cover the limbs
Repellent – especially on children and the elderly.
Protection of people sick with dengue
Prevention of Multiplication of Mosquitoes
Drain water from coolers, tanks, barrels, drums, buckets, etc.
Remove all objects, such as plant saucers, etc. which have water collected in them from house.
Cover all water containers at all times.
Discard solid waste and objects where water collects: bottles, tins, tires, etc.
