Abstract: AIM: To make an epidemiological survey of infestinal acariasis in Huainan area, Anhui Province. METHOD: Case history, stool examination (saturated saline flotation method), and blood examination (differential leukocyte count). RESULTS: Stool examination of 3 312 subjects showed that 218 were mite positive, the detection rate being 6.6%. For mites thus detected, 7 species had been found, i.e., Acarus siro, Tyrophagus putrescentiae, Dermatophagoides farinae, D.pteronyssinus, Carpoglyphus domesticus, Glycyphagus domesticus, and Tarsonemus granarius. 30 out of the 218 intestinal acariasis cases further examined for eosinophilia had an average count of 0.17×10⁹/L(0.32- 0.78×10⁹/L). The main clinical symptoms were abdominal pain, diarrhea, and pyohemofecia. CONCLUSION: For personnel working at their specific vocation, the need for reinforcement of knowledge of prevention should be stressed.
