How long is the incubation period for tuberculosis?

The incubation period for tuberculosis is usually seven to fourteen days. After infection with Mycobacterium tuberculosis, it may not immediately show the phenomenon of infection. If the constitution is strong, or the infected bacteria are few, it will generally not show the phenomenon of infection. Then after infection, beyond the incubation period, there may be no obvious symptoms. As the disease worsens, it will show some obvious symptoms of tuberculosis, such as cough, chest tightness, bloody sputum, low fever and other diseases. Therefore, when showing this disease, we should go to the hospital for examination and treatment in time.
