Epidemiological study of parasitic infestations in lower socio-economic group in Chandigarh (north India).
When stool samples from 970 subjects belonging to lower socio-economic groups were examined for parasites, a total of 121 subjects (12.5%) i.e., 57 (12.1%) males and 64 (12.9%) females showed positive results. The overall prevalence of parasitic infestation did not correlate with sex, caste or religion and living conditions. However, the prevalence was higher in hospital employees residing in well sanitated area. Giardia lamblia (69.5%), Entamoeba, histolytica (15.7%), Hymenolepis nana (12.4%), Ancylostoma duodenale (10.7%), Ascaris lumbricoides (8.3%) and Taenia (0.8%) were the parasites seen.
