Filarose

Filariasis, or elephantiasis Brazilian, is caused by the nematode Wuchereria bancrofti and occurs only in humans. He has as transmitters of the disease female mosquitoes of the genus Culex, Anopheles, Aedes and Mansonia, intermediate hosts typical hot and humid climate.

The mosquito becomes infected when it bites a human patient and the infectious forms are lodged mainly to the animal's head.

When bitten a person, the worm larvae penetrate the bloodstream and are directed to the vessels and lymph nodes. When the adult form, about three months later settle in the lymphatic system, blocking them and causing vessel dilation and accumulation of lymph in the affected regions - being one of the leading leg.

In these tables - that occur in approximately 15% of cases, about 10, 15 years of infection, there is hardening, thickening and hypertrophy of the board, a considerable increase in volume and to deformations.

The larvae derived from adult forms, those housed in the lymphatic vessels, circulate throughout the body via the blood.
Treatment
Treatments are made with chemicals and, in the case of drug resistance, may be required surgical removal of the worm.
Prevention
The prevention of filariasis should be made through hygienic measures and combating the mosquitoes that transmit the disease. Some forms of prevention are:
Use of mosquito nets with insecticides or curtains, which prevent mosquitoes counted with the man.
 Spraying insecticides in the home.
 Extermination of larvae with chemical agents.
  Wearing clothes that cover most of the skin as possible when in risk areas.
 Repellents.
 Avoid standing water.
 Inform the community about the risk of disease.
Filariasis, also known as elephantiasis, is an infectious disease that affects the lymphatic system, blocking circulation. The transmitting agent is a mosquito, which should be eliminated with preventive measures mentioned above.
