With these two factors taken into account, water which showed only marginal significance in the exploratory analyses was no longer significant ( χ 2 1 = 2.046, P = 0.153).

Furthermore, living in rural areas was significantly associated with combined protozoan infection in the asymptomatic population, whereas, in the symptomatic population an increasing trend of protozoan infection was detected in the hot season.
Results A highly significant difference of prevalence was found between symptomatic (82.3%) and asymptomatic subjects (14.9%), with the majority attributable to protozoan infection.
