Tuberculosis can develop at any age, and the likelihood of Mycobacterium tuberculosis infection is higher whenever the body’s resistance is significantly reduced. Once Mycobacterium tuberculosis is infected, the signs and symptoms of tuberculosis will appear. Tuberculosis infection in children is also called primary tuberculosis, while in adults it is secondary tuberculosis. Currently, the incidence of tuberculosis in China is on the rise again. Therefore, it is important to strengthen physical exercise and balanced nutrition, and never be picky about what you eat. At the same time, avoid overwork and stressful life and work, so as to ensure that the body’s resistance and immunity are in a normal state and reduce the possibility of infection by Mycobacterium tuberculosis.
