Mosquito and Mosquito Borne Diseases in Wetlands

 Mosquito and Mosquito Borne Diseases in Wetlands

Mosquitoes are dipteran bloodsucking insects that have been surviving on earth since millions of years. They have been always ravaging population of human as important carriers of various diseases. People fight globally against mosquitoes and mosquito borne diseases, but still have no sustainable remedy. Malaria, dengue, filariasis, Japanese encephalitis, westnile and Chikungunia are the major vector borne diseases spread globally by different mosquito which have serious public health implications on humans. The increase in density of a vector species is very much depends on various factors like climatological, environmental changes, manmade errors etc are favorable for its breeding and survival. Water is essential for mosquito breeding. All mosquitoes require standing or slow running water or moist soil to breed, but the type of water they prefer depends on the species. The wetland ecosystem provides food, water and shelter for all kinds of animals. Invertebrates that live all or part of their lives under water, such as mosquitoes and dragonflies. Among the most obvious inhabitants of wetlands are mosquitoes, the family Culicidae in the order Diptera, with about 3200 species spread worldwide. Mosquitoes are found throughout the world except Antarctica.

 

The Determinants of health:

Health  determinants  are  factors  that  influence the health. They can be arranged hierarchically, as demonstrated in Figure-1, as concentric spheres that move outwards progressively from the individual. These categories and subcategories of health determinants can be used as a framework to structure the analysis of the association between particular wetland types and health in specific settings. There are complex interactions between health determinants that we cannot generally capture by mathematical  models. Many of  the health determinants can change in both positive and negative directions. In doing this, they can enhance or diminish the health outcomes  experienced  by  the  community. Some of the health determinants can be managed so  as to enhance community health, for example the quality of water supplies.
