If it is simple tuberculous pleurisy, you can live with your family, if it is also combined with tuberculosis, you need to be isolated and treated. Tuberculosis is a respiratory infection that can be discharged into the air through sneezing, sputum, and loud speech. If droplets containing Mycobacterium tuberculosis are inhaled, Mycobacterium tuberculosis enters the body and causes infection. Tuberculous pleurisy is tuberculosis that occurs in a closed pleural cavity, which is not connected to the outside of the body and cannot expel tuberculosis bacilli elsewhere, so simple tuberculous pleurisy is not contagious and does not require isolation. However, some patients with tuberculous pleurisy are accompanied by tuberculous foci in the lungs and may be infectious. They should be isolated and the living environment needs to be sterilized. But even if tuberculous pleurisy is not contagious, you should pay attention to regular sterilization and disinfection, take medication on time, and your family members should have regular checkups and get vaccinated in advance to reduce the possibility of being infected. Patients are advised to consult a medical professional for advice.
