Dysentery is widespread intestinal infection, especially frequent during a hot season. Infection occurs from the sick person, at non-compliance with rules of hygiene. It is possible to catch dysentery through dirty arms, dirty water which was used for washing up fruit and vegetables, badly thermally processed products.
Bacteria cause an inflammation of large intestine walls. The main symptom is a frequent liquid stool, not too plentiful, dark green color, containing slime, pus, blood. There are false urges to defecation (tenesmus). Overall health worsens, the patient is excruciated by nausea and vomiting, appetite strongly decreases, there is a headache. Dehydration is possible.
Dysentery is treated at a hospital. Two problems should be solved at treatment: destroy a microbe originator with antibiotics and recoup liquid loss with plentiful drink, if necessary intravenous injections of special solutions.
If the patient has a good immunity, illness is completely cured in a week, but sometimes gains relapsing wavy character (happens in people who have not carried out the prescribed treatment completely), it threatens with emergence of a chronic form.
During illness it is necessary to control thoroughly possible complications: rupture of intestine, dehydration. Damage of intestinal wall integrity requires an urgent surgical intervention.
In people who had the disease, unstable immunity develops, and repeated infection sometimes happens.
