Bacillary dysentery bacillary dysentery patients and carriers is a source of infection, and harmful bacteria depends on the number of each stool and exclusive duration and bacteria to spread in the population opportunities. Row of patients with acute dysentery bacteria volume, but the duration was short; chronic bacillary dysentery patients with sustained, long time, but the row of bacteria less, carriers, especially chronic occult activities in the crowd as usual, the set in the wide extent, is more than the patient as an important source of infection. Carriers can be divided into a convalescent carriers and healthy carriers, the former contaminated period of one for 2 – 3 weeks, but in recent years because of drug-resistant strains increased, contaminated also extended the deadline, there are up to 4 months or more, the latter seen in patients with bacillary dysentery contacts.
Shigella bacteria with the feces of patients and carriers in vitro, polluting the external environment, through contact with life, food, water, flies and hand-oral infection. So called “fecal – mouth” approach.
Life contact means contact with patients or carriers infected with everyday appliances, such as door handles, blankets, beds, toys, furniture, etc.; these items have a certain amount of dysentery bacteria detection rate. Hands are contaminated carrier rate could be as high as 15%, so dirty hands play an important role in disseminating information, especially in children.
Whether patients with bacillary dysentery or a carrier, if engaged in catering, food industry, cooks, nurses, water supply, etc., contaminated food or water may give rise to an outbreak of epidemic, a greater threat to the population.
