This study aimed was determining the prevalence of Parasites causing diarrhea in Gorgan .
Material and Methods: This cross-sectional study was performed on 1086 Patients with acute diarrhea. The test was performing by the wetmount and formalin-ether concentration method according to WHO protocol.
Results: From 1086 patients in study, 197 (18.1%) were infected by intestinal parasites, that 141 (13%) were infected with Protozoan and 79 (7.27%) were infected with intestinal worms.
