Regarding the statement that tuberculosis is a disease of the poor, it is mainly due to the lack of knowledge, poor nutrition, and poor living environment in poor areas, which affects the prevention and treatment of tuberculosis and makes it more likely to occur. However, the disease itself does not discriminate in the sense that people with inadequate prevention and control can be infected. 1. Lack of knowledge: People living in poor areas have limited resources for the popularization, education and promotion of tuberculosis. People do not know enough about tuberculosis and do not pay attention to it, and when there are active tuberculosis patients around, they cannot do the principle of disinfection and isolation, and in the long run, cross-infection among residents will cause the spread of tuberculosis; 2. Poor nutrition: Since tuberculosis is a consumptive disease, most residents in poor areas have poor nutrition, and these residents often have to do physical labor, which will make their bodies Once attacked by tuberculosis bacilli, they are easily infected; 3. Poor environment: People in poor areas live or work in crowded places with poor sanitation, where bacteria and viruses tend to accumulate, and poor air circulation in these places makes it easier for others to catch active tuberculosis once someone around them is infected. In addition, people with poor economic conditions do not have access to better medical conditions, and some even choose not to seek medical treatment, which leads to a high incidence of tuberculosis disease in poor areas and a low cure rate.
