BackgroundHookworm was a previously dominant parasitic infection in Southern Thailand. The changing population to an aging society in Yo Island has never been investigated for intestinal parasites. This study aimed to estimate the prevalence of hookworm and intestinal parasitic infections on Yo Island, a small island in Songkhla Province of southern Thailand.MethodsA cross-sectional study was conducted among volunteers aged 15 and above to give one stool sample that was screened by wet mount for intestinal parasites and the modified Harada-Mori culture (mHMFPC) which is adapted from HMFPC, using local plastic bag containers instead of test tubes for hookworm detection.ResultsTwo hundred forty-seven volunteers (females = 160) gave one stool. The highest participation was in age group higher than 60 years. Most were Buddhism (89.1%), agriculturist (71.4%), non-education (87.9%), and income lower than 9000 baht (50.2%). The prevalence of intestinal parasites was 13/247 (5.3%) of which 6/247 (2.4%) were positive for hookworm species Necator americanus. One volunteer was coinfected with hookworm and Strongyloides stercoralis and another with Endolimax nana and Blastocystis hominis. The mHMFPC detected more positive stool samples than wet mount and wet mount: 5 vs. 2.ConclusionsParasite prevalence was low in this urban community of mostly low-income village dwellers. The mHMFPC appeared better at detecting hookworm but numbers were small. Combined techniques are suitable for field use.
