Epidemiology
W. bancrofti is responsible for 90% of lymphatic filariasis. Recently, 120 million worldwide cases of lymphatic filariasis were estimated. W. bancrofti largely affects areas across the broad equatorial belt (Africa, the Nile Delta, Turkey, India, the East Indies, Southeast Asia, Philippines, Oceanic Islands, and parts of South America.)
The mosquito vectors of W. bancrofti have a preference for human blood; humans are apparently the only animals naturally infected with W. bancrofti. There is no reservoir host.
