Background: Dysentery is an inflammatory bowel disease (IBD) caused by microorganisms invading the intestinal mucosa.
Objectives: This study aimed to determine the epidemiological profile of dysentery and identify associated risk factors in South Khorasan Province, Iran.
Methods: This cross-sectional study was conducted on 1181 patients with dysentery during 2016–2020 in South Khorasan Province, Iran. Data were collected through the disease surveillance system.
Results: The highest prevalence of dysentery was observed in counties such as Sarbisheh, Zirkooh, Darmiyan, and Nehbandan. Men accounted for the majority of cases (n = 639, 54.1%), while children under the age of 6 accounted for 30.6% of all cases. Shigella species were responsible for 48.2% of all cases of dysentery.
Conclusion: Shigella and E. coli were the most common causative agents of dysentery in South Khorasan Province, Iran. Additionally, counties located near the borders had the highest prevalence of diarrheal diseases.
