Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Yes it can transmit to other family members if you are not completely treated. Wearing a mask can prevent infection transmission to other members via respiratory tract. In my opinion you should test yourself for the TB test. If you are free from the TB there is no need to worry. But if you are currently infected with TB than you should take complete treatment so other family members won t infect with it. Your wife must be having good immunity against the TB that is why she won t infected until now. Your baby will have same immunity as her mother is having so you can allay the fear that your baby will be infected with it. You can have high protein and carbohydrate diet. Avoid single binge eating, instead you can have small frequent diet. Daily exercise, meditation and healthy living can keep you away from the all the medication. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
