Laboratory staff can often infect bacteria from the skin and mucous membranes. When eating raw milk, dairy products and unboiled boiled animal meat, the bacteria can enter the body from the digestive tract.


In addition, germs can also be infected through the respiratory mucosa, eye conjunctiva and sexual organ mucosa.

In China, sheep-type cloth disease is more common, the natural course of untreated people is 3 to 6 months (average 4 months), but can be only 1 month or more short. The course of the disease can generally be acute and chronic, the acute stage of the bovine type is not obvious. The incubation period is 7 to 60 days, usually 2 to 3 weeks, and a small number of patients become ill months or more after infection. Most of the infected people in the laboratory became ill within 10 to 50 days.
