This is a zoonotic infectious disease, because it is infected with Brucella, which mainly comes from cattle and sheep and is distributed in embryos, milk, meat, viscera and fur of cattle and sheep. Once people come into contact with this kind of bacteria, they may invade the human body through skin mucosa, digestive tract and respiratory tract.
Brucellosis patients are often weak and lazy all day, so this disease is also called "lazy disease".
Will not spread from person to person.
There is no need for isolation after onset.
After people suffer from brucellosis, the first symptom is fever, which is wavy, that is, high fever for a few days, then body temperature drops for a few days, and then starts to rise again and again. Some people have atypical fever symptoms and may have irregular fever. Another feature is hyperhidrosis, especially in the early stage of onset, and sweating more at night. Patients may also have pain and swelling of bones and joints. Experts remind that once the symptoms of brucellosis are found, you should go to the hospital or go to the CDC for testing in time.
Because Brucella is not heat-resistant, if you stew beef and mutton, you can usually kill the bacteria at 100℃ for more than 4 minutes. If it is dry and hot, such as baking, it takes more than 7 minutes to kill Brucella at 100℃.
If you want to stay away from brucellosis, it is recommended to do the following:
First, don't eat raw or undercooked beef and mutton. When eating shabu-shabu and iron plate barbecue, be sure to cook the meat thoroughly.
Second, the placenta is the part with the most bacteria in sick animals. Try to eat as little as possible, and it is best not to cook it yourself.
Third, go to supermarkets, farmers' markets and other formal channels to buy beef and mutton.
Fourth, when cooking beef and mutton dishes, you'd better wear gloves to wash and cut the meat.
