Abstract:

Objective To determine the distribution of the foci of Angiostrongyliasis in parts of Yunnan province, providing the basis for prevention and control of its infection. Methods The investigation was conducted in accordance with the requirements of the survey program on Angiostrongylus cantonensis issued by the Ministry of Health. Results A total of 7 intermediate hosts of A. cantonensis were found at the sampling sites. Pomacea canaliculata was distributed in 13 of the 19 surveyed counties, accounting for 68.42%. Of the 3874 captured snails, P. canaliculata accounted for 51.83% and Achatina fulica accounted for 6.56%. The positive infection rates of 3rd instar larvae of A. cantonensis found in Jinghong and Mengla counties were 0.56% and 0.26%, respectively. Conclusion The natural foci of Angiostrongyliasis are present in Yunnan.
