A cohort study to identify incidence and risk factors of hookworm infection was conducted in a rural community, central Thailand from November 2005 to February 2007. Stool specimens were examined for hookworm eggs using wet preparation, Kato thick smear, and water-ethyl acetate sedimentation technique. The incidence rate of hookworm infection was 7.5/100 person-years. The independent risk factors for acquiring hookworm infection were barefoot walking (incidence rate ratio [IRR] = 4.2, 95% confidence interval [CI] = 1.2-14.5) and raising buffaloes around the house (IRR = 4.8, 95% CI = 1.9-11.8). Sequencing of internal transcribed spacer 1 (ITS1)-5.8S-ITS2 region of the ribosomal RNA gene were..
