There are three Regional Filaria Training and Research Centres (RFTRC) functioning at Calicut in Kerala, Rajahmundry in Andhra Pradesh and Varanasi in Uttar Pradesh. These centres were established during 1955, 1963 and 1965 respectively and conduct training courses for personnel for the National Filaria Control Programme Units in different regions of the country. These centres also undertake research projects on different problems of Filaria. A centre was established at Thuravoor in Kerala state in 1966 to undertake a pilot project for the control of malayan filariasis which is a special problem in that state. This unit has been converted into a research unit since 1980 with head quarters at RFTRC, Calicut and Field station at Shertallai (Kerala).
