Hi & Welcome to HCM. I appreciate your concern for the possible spread of TB. Active TB involving the lungs is highly contagious if it is not treated. TB spreads through the air. When a person with active TB sneezes, coughs, or talks closely to others, bacteria are passed through tiny drops of fluid from the mouth and nose that are unknowingly breathed in by others. Kissing or having physical relations with your husband will not transmit the disease. However, all the close contacts including your husband should be screened for active TB and if found positive should be given the treatment. TB only cause infertility when it involves the fallopian tubes. It is a treatable condition, you must avoid drugs like Streptomycin and Pyrazinamide during pregnancy as these anti TB drugs can produce harmful effects in the growing fetus. Once you get well, you will not have any problems. Hope to have answered your query.
