Bacterial dysentery, referred to as bacillary dysentery, is a common intestinal infectious disease caused by Bacillus dysenteriae. Bacterial dysentery patients and carriers are the source of infection, mainly through the gastrointestinal route, infected by contaminated food, water, hands, flies, etc., and the population is generally susceptible. The main clinical manifestations are abdominal pain, diarrhea, urgency and mucopurulent stools, may be accompanied by fever and systemic toxemia symptoms, severe cases have infectious shock and/or toxic encephalopathy. Bacillary dysentery occurs in summer and fall, but can be seen in disseminated patients throughout the year. The incubation period is about 1~2 days. Clinical manifestations in the acute phase are chills, fever, temperature up to 39℃, headache, fatigue, loss of appetite, nausea, vomiting and other toxic symptoms, abdominal pain, diarrhea, defecation lO~20 times a day, pus and blood stool, and a sense of urgency and heaviness. Chronic bacillary dysentery patients have a history of acute bacillary dysentery, more than two months of illness and the disease has not been healed. Toxic type is seen in children aged 2~7 years old, with a rapid onset, dangerous disease, and high fever of over 40℃. It is accompanied by severe systemic toxemia, depression, drowsiness, coma and convulsions, and circulatory and respiratory failure can occur rapidly, so severe toxemia, shock and/or toxic encephalopathy are the main clinical manifestations, while the intestinal symptoms are mild or even no abdominal pain and diarrhea at the beginning. Diarrhea and dysentery-like stools may appear within 24h after the onset of the disease. According to the different clinical manifestations, there are 3 types as follows.
