چکیده
The prevalence of hookworm infection is as high as 95% in certain communities of developing countries particularly in the tropical and sub tropical areas (Hoagland and scad, 1978; walsh and warren, 1979). The chronic internal blood loss caused due to hook worm infection is associated with iron deficiency anaemia, protein, folic acid and vitamin B12 (Roche and Layrisse, 1996; Woodruff, 1982; Li, 1990). Hookworm infection alone is causing 50,000 deaths per year worldwide (Walden, 1991). Heavy hookworm infections may lead to retarded growth of children (Hotez and Pritchard, 1995; Stoltfus et al., 1997). A direct relationship between the intensity of hook worm infection and anaemia (Lwambo et al., 1992).Climate, socio-economic, educational and environmental sanitary conditions may influence the prevalence and severity of hook worm infections (Kan, 1989; Bakta et al., 1993). Necator americanus and Ancylostoma duodenale occur commonly in tropical and sub-tropical regions of human population. Of these A. duodenale was found to be abundant in rural and urban communities (Gallies, 1985; WHO, 1994). Information regarding prevalence of hookworm infection in South India is lacking. Hence, a new vista has been opened to asses the occurrence and clinical significance of the hook worm infection in rural population living in Vangayagudem.
