Vector is a living organism which carries the disease through their bodies of different individual. The vectors are carriers and these are rate, snails, arthropods etc. vector borne diseases are caused by two ways of transmission i.e. mechanical and biological. In mechanical transmission, the disease causing agents are transported by flying insects or through discharge of exretarory materials. In the biological transmission the disease causing agents maintain the life cycle in the host. The hosts may be man, vertebrates, arthropods etc. Some examples of vector borne, diseases are flying insects or through discharge of excretory material. In the biological transmission, the disease causing agents maintain the life cycle into host. The hosts of primary host and secondary host. The hosts may be man vertebrate’s arthropods etc. Some examples of vector borne diseases are-
Example of Vector Borne Diseases:
-
Malaria parasite causes, malaria disease. The primary host is man and vector is female anopheles mosquito.
-
Pleague bacilli in rat
-
Schistosomiasis disease occurs from man to snail to man.
-
Encephalitis disease occurs from bird to anthropoids to man.
-
Fish tape worm disease occurs from bird to arthropod to man.
-
Fish tape worm disease occurs from, man to Cyclops to man.
Control of Vector-borne diseases:
The vector borne diseases can be controlled by environmental method, chemical, biological and genetically ways.
Environmental Control:
-
Elimination of breeding places
-
Proper water management
-
Elimination of water material
-
Adequate cleanliness and proper education to the people.
ADVERTISEMENTS:
Chemical Control:
-
Use of mineral oils
-
Use of insecticides
Biological Control:
-
By the use of fishes, like gamhusia control mosquito.
-
By use of fungi
Genetic Control:
-
By sterilizing the male insects
-
By application of insect growth regulators
-
By chemosterilants
-
By use of pheromones
