parasites are transmitted to humans through mosquitoes. There are three forms of the parasites which are Wuchereria bancrofti‚ Brugia malayi and Brugia timorican. The most common is Wuchereia bancrofti. When the mosquito bites the human‚ it injects the larvae into the blood stream which then circulates into the lymphatic system.
