The dengue virus is passed to humans exclusively by the bite of female mosquito known as Aedes Aegypti in search of a blood meal. This made of transmission makes the dengue virus an arbovirus (that is, one that is transmitted by an arthropod). Studies have demonstrated that some species of monkey can harbour the virus. Thus, monkeys may serve as a reservoir of the virus.
Mosquitoes who bite the monkey may acquire the virus and subsequently transfer the virus to humans. The dengue virus also fails the immune system of mosquito (Ades). The virus is taken up with an infected blood meal from which it will first infect the mosquito gut tissue. From the gut it migrates to other parts of mosquito, including the salivary glands, from where it can be transmitted to another human upon a second blood meal. In this study we observed that the mosquito utilises its innate immune system to control dengue virus infection. Infection with the virus may result in the activation of mosquito immune response.
There is no way to diagnose that mosquito is carrying the dengue virus or not. Therefore, people must protect themselves from all mosquito bites. Dengue mosquitoes breed in stored/exposed, water collection systems. The favoured breeding places are barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, discarded bottles, tyres or water coolers, and other places where rain water collection or is stored. Mosquito eggs develop to larva in two days.
Not last but least to overcome this national problem, Faculty of Veterinary Sciences of Bahaud din Zakria University Multan has come forward. We as students arranged the groups of students under the supervision of Dr Mazhar Ayaz (parasitologist). These students were informed and assigned to inform the people about the cure and control of dengue virus. We are collecting samples of water from the different areas of Multan Division and are doing research work in laboratory. There is a need of proper management to overcome this situation and students of F.V.S under the supervision of Dr Mazhar Ayaz have committed to controlling this situation by physically,pshycologically and proper vector-control.
