On average a Dengue fever also known as break bone fever. It is an infectious tropical disease caused by dengue virus. The mosquito responsible for dengue is Aedes aegypti including most species of mosquito. Dengue Fever (DF) and Dengue Hemorrhagic Fever (DHF) are the most common mosquito borne viral disease in the world. It can be fatal.

Female mosquito can lay eggs up to300 during its life span of 14-21 days.

Transmission of disease:
Mosquito bites and sucks blood containing the virus from an infected person and then transmits into a healthy one on biting. So, we can say that it acts as a vector for transmission.

BIOLOGY:
There are four types of dengue virus known as serotypes referred as DENV-1,DENV-2,DENV-3 and DENV-4.Dengue virus genome contains about 11,ooo nucleotide bases that code for 3 three different types of protein molecules(C,prM and E)

Symptoms:

5. Bleeding from the nose and mouth.
It is an RNA virus of the family Flaviviridae and genus Flavivirus.

PREVENTIONS:
No specific vaccine is introduced yet.
Bed rest and hydration therapy.
Aspirin should be avoided because of anticoagulant properties.
Use of insecticides indoor.
Cover all toilet bowls in your home.
Turn over all water storage containers
The patient should consult the doctor as soon as possible and make laboratory tests not more than 90 rupees of tests.

CONCLUSION:
It has become an endemic disease causing a serious threat leading to death in severe cases. Now a day in Punjab due to steps being taken by the Government it has been overcome while last years there were a lot of cases in Punjab and worldwide. So, it needs preventions and precautions made by public and Government, There should be a proper awareness among people either through mass media or print media and also by the extension workers.
