Dysentery, caused by bacilli and amoebae, is a highly contagious disease. Transmission occurs when microbes from the stool of an infected person enter another person's digestive system orally. This spread typically happens when an infected individual does not adequately wash their hands after using the toilet, leading to the dissemination of microbes to food, water, surfaces, or direct contact with other people. Contaminated water and uncooked foods are significant sources of transmission, particularly in regions with inadequate hygiene conditions.
