It originated from the visit of Bill Gates and Melinda Francci Gates to China. According to the WeChat WeChat official account Gates Foundation, which inquired about the Gates Melinda Foundation, in 2008, Bill Gates and Melinda Francci Gates came to a village in Hainan, China to visit tuberculosis patients. "It was a sad visit," Bill said with emotion when he recalled a mother with recurrent tuberculosis. "This lady has been treated for tuberculosis for several months, taking as many as 13 tablets at a time, but she is still thin, coughing constantly and losing her ability to work." This experience prompted the Gates Melinda Foundation to pay attention to tuberculosis. Since 2009, the Gates Foundation began to cooperate with the National Health and Wellness Committee to carry out tuberculosis prevention and control projects, establish and implement a new prevention and control model for tuberculosis and multidrug-resistant tuberculosis, and effectively prevent and control tuberculosis from diagnosis, medical care, management and financing, thus reducing the burden of disease and saving more lives.
