[Research of water contact and labor practice of residents in plateau mountain schistosomiasis endemic areas in Yunnan Province].
OBJECTIVE
To understand the status of water contact and labor practice of residents in plateau mountain schisto- somiasis endemic areas in Yunnan Province, so as to provide the evidence for formulating the strategy of prevention and control of schistosomiasis in the next step of work.


METHODS
A total of 412 residents aged 6-65 years old in 2 villages were randomly sampled and investigated with questionnaires for their water contacts and labor practices in plateau valley schistosomiasis endem- ic areas. Then the schistosome infection status of the residents was surveyed with the indirect hemagglutination assay (IHA). RE- SULTS: Among the 412 residents investigated, the rate of water contact was 88.35%, and the main causes of water contact were watering, and swimming and playing. The percentages of residents who had schistosomiasis history were 1.16%, 0.00%, 30.80%, 3.85%, and 0 in them who had swimming and playing water-contacts, bathing, watering, washing hands, and others, respectively (χ2 = 38.96, P < 0.01). The positives of IHA in the above-mentioned residents were 18.60%, 0.00%, 37.60%, 23.08%, and 0, respectively (χ2 = 12.61, P < 0.05).


CONCLUSIONS
The productive infested water contact is the main way of schistosome infection. Therefore, the changes of labor practices and water contact of the residents are very important for the ef- fective prevention and control of schistosomiasis transmission.
