ABSTRACT
A total of 1377 tribals, comprising Irulas (536), Paniyas (196), Kurumbas (87), Mullukrurumbas (156) and Soligas (402), living in the Nilgiris, Tamil Nadu, India were studied for sickle cell trait between 1981-85. Patients attending various tribal clinics at Arayure, Kozhikarai, Kothagiri and Biligiri Rengan hills for various ailments were screened at random by solubility test and by acetate paper electrophoresis, if required. HbAS carrier frequency was 30-37.8 per cent in all the tribals studied except Kurumbas (19.5%). The frequency of carriers were more (37.8%) on the western part of Nilgiris (Nedungode, Kappala and adjoining regions) than the eastern part (30%). Further, the prevalence of carriers was higher (47-49%) in the 10-19 yr age group amongst Paniyas and Mullukurumbas living in the western part of Nilgiris. An episodic, epidemic of malaria so rampant during the early part of this century in the western parts of Nilgiris might have eliminated many children with HbAA and hence the higher frequency of HbAS in this particular age group.
