Introduction

Introduction

It is an inflammatory disease characterized by severe diarrhea with blood and mucus in the stools. It is accompanied by pain in the abdomen, and sometimes, contracting spasms of the anus with a persistent desire to empty the bowels (tenesmus).

Dysentery may have several causes, such as parasites (worms), chemical irritants, bacteria and protozoa (amoebae). But, there are two main infectious forms that affect humans: Sonne dysentery, caused by the bacteria (Shigella sonnei) and amoebic dysentery, caused by an amoeba (Entamoeba histolytica). Both forms are transmitted by contaminated water or food. Dysentery is particularly common in tropical countries where standards of hygiene are poor.

Precautions

Since dysentery is more common in tropical countries, it is important to avoid eating uncooked foods and ensure that all foods are prepared in the most hygienic way. It is essential not to drink unboiled water, because this may carry the infection. All foods must be kept covered to prevent flies from contaminating them with the disease.
