Lymphatic filariasis is a crippling disease which affects the health status as well as economic condition of a person and also the society. Many attempts are made by scientists all over the world to control the filarial worm as well as vector. But nature plays important role in controlling the filariasis.
Methods: To have some clear picture on how nature helps to control transmission of filarial disease, four slums of Burdwan (Hatgobindapur, Pandaveswar, Jamuria and Memari) were sampled for Daily survival rate (DSR), Daily Mortality Rate (DMR), Presumptive Mortality Rate (PMR) and Ovariolar dilatatations.
Results: Lack of synchronization between the highest vector density and transmission disease, fall in parasitic load, mortality between two successive gonotrophic cycles, rise and fall in temperature and humidity is noticed in all the four slums which help to keep the check on transmission level of filaria by nature itself.
Conclusions: Factors behind the natural phenomena of control is reflected in this article which perhaps helps to adopt strategies for effective control.
