tuberculosis

Tuberculosis is commonly known as "pulmonary dysentery". It is a chronic infectious disease with strong contagion caused by the invasion of tuberculosis into the human body. It is not affected by age, gender, race, occupation, and region. Many organs and systems of the human body can develop tuberculosis, with tuberculosis being the most common. More than 90% of tuberculosis infections are transmitted through the respiratory tract. Patients with tuberculosis cough, sneeze, and make loud noises, causing droplets of tuberculosis bacteria to spray out of the body, and inhaling them to become infected. Its typical manifestations are: cough, expectoration, hemoptysis, chest pain, and dyspnea. It is a chronic infectious disease that has a long history of endangering human health. It has spread worldwide and caused millions of deaths. China is now one of the 22 countries with a high burden of TB in the world, and the number of TB patients ranks second in the world, behind India. At present, there are an estimated 2 million infectious tuberculosis patients in China.
