This research was carried out to assess the relationship between the rate of diarrhea and surface water quality inside full-dyke of Cho Moi Distric, An Giang Province in the dry and rainy seasons. Resurts showed that the water quality in the full dyke area was contaminated with organic matter and phosphate. The concentration of BOD, COD and P-PO43- exceeded the allowance value of the national techmical regulation on surface water quality QCVN 08:2015/BTNMT, used for domestic purposes from 1.15 to 2.44 times, 1.92-3.26 times, and 1.3-3.75 times respectively. Coliforms detected at 12 of 15 sampling points exceeded 1.86 to 92 times, comparing with the standard. Wastes discharged from breeding activity of cattle (e.g pigs and cows) contributed to water polluted. Contaminated surface water negatively influenced the health of local people living inside the full-dyke area, with rather high correlation (Rs = 0.7). Of in which coliforms in water was the most likely parameter which can be pose of diarrhea for human.
