Environmental Factors of Malaria Persistence: A Study at Valiyathura,Thiruvananthapuram City

In Kerala, malaria had been eradicated as early as in 1965. But imported malaria used to occur even thereafter; and indigenous malaria showed signs of resurgence from 1969 onwards. Recently an increasing trend of both imported and indigenous malaria cases has been observed. Malaria began to occur in epidemic proportions in the coastal areas of Thiruvananthapuram city since 1994, Moreover,the disease persisted in the area during 1995 and 1996 despite control measures implemented by the health care personnel of the State Government. Theis study was carried out in Valiyathura to explore the environmental factors influencing the persistence of malaria in this coastal area [Discussion Paper 3].
