“If an infected person is bitten by a black fly, some of the microfilaria are ingested during the blood meal.”

“In a heavily infected person there can be 100,000 or more microfilaria dying every day.”

“These microfilaria have a life span of 6 months to 2 years, and migrate throughout the body.”

“The result also showed that microfilaridermia and mean intensity decreased as the number of treatment taken increased.”

“Transmission occurs when a mosquito bites an infected human, picking up the microfilariae, which develop into larvae.”

“After mating, the female viviparously produce microfilariae which move throughout the circulatory system and are taken up by the mosquito host.”

“Over a week or so, these microfilariae develop into infective larvae and can be transmitted when the fly bites another person.”
