The most vicious female chef in America did not wash her hands after going to the toilet, resulting in hundreds of deaths. What happened next?

There is an old saying in China: How can you sweep the world without sweeping one house? Although this is an old saying about personal ambition and foresight, in a smaller way, it is also about personal hygiene. In fact, the root cause of many diseases is that people fail to pay attention to their personal hygiene, which ultimately leads to some patients becoming seriously ill. In fact, there is an old saying in China that diseases come from the mouth, which means that many diseases are caused by people's own food. However, the most terrifying thing is that if the chefs who make some delicious food do not pay attention to personal hygiene, what will they make? No matter how good the food is, it may lead to tragedy.

Mary was born in Ireland in September 1869, and her family immigrated to the United States in 1884. At that time, because Mary was forced to make a living, she could only work as a maid in a wealthy family's home. However, the owner later discovered that Mary had a good advantage, that is, the rice she cooked was so delicious, so she immediately became a maid. Transformed into a chef, Mary not only gained a lot of fame through her profession as a chef, but she also earned a lot of money. But what the owner didn't expect was that Mary, who could make delicious food, was unwilling to wash her hands when going to the toilet, and ended up bringing the bacteria on her hands to the whole family.

In the summer of 1906, when the scorching heat had not officially passed, Mary did not wash her hands when she went to the toilet. The bacteria on her hands eventually caused the entire host family to be infected with typhoid fever. The owner was first temporarily saved in the hospital, and then after being discharged from the hospital, the owner was eager to find out the cause of the family's illness, so he invited Sobo, a scholar who specializes in typhoid fever, to investigate the matter. Sobo soon focused his attention on the chef Mary. After investigation, it was discovered that Mary had had 7 different job responsibilities before. Other colleagues centered on Mary also developed typhoid fever one after another, so From these eight cases of typhoid fever, disease investigator Sobo determined that this series of infection cases probably came from Mary.

But Sobo's research progress was quickly blocked when he got close to Mary, because Mary was extremely uncooperative, and was even treated with force when Sobo tried to communicate well with Mary. Such an ending left Sobo with no choice but to apply for assistance from a local health worker. However, when five police officers came to her door, Mary still refused to give in and even refused to cooperate with the investigation. Because Mary dismissed the hypothesis of the origin of the disease put forward by Sobo and believed that her body was healthy. However, when other people got sick and she was the only one who did not get sick, it meant that the disease had nothing to do with her, and it also proved that her body great.

In the end, under the hostage of the police and local health workers, Mary was finally forced to cooperate with Sobo's research and investigation. The final conclusion was that Mary did carry some viruses in her body, but These viruses have become friendly with some of the antibodies in Mary's body, so nothing strange can be seen in Mary's body. But anyone who has had some close contact with Mary, no matter how healthy they are, may get some infectious diseases.

Then in 1907, the Mary virus in the United States caused a wide range of typhoid fever in parts of the Northeast. Although Mary had been fired by her original employer, she quickly found an opportunity to work in a restaurant with her excellent cooking skills. However, because Mary was really unwilling to take care of her personal hygiene, her habit of not washing her hands when going to the toilet was retained. As a result, the scope of the infectious disease became wider and wider. In the end, seven people died of the disease and hundreds of people had to Hospitalized due to illness.
