Is tuberculosis contagious?

I am 29 YR old male. My wife was pregnant by the time when I stated to have random fever intermittently for 15 days (no other symptoms except fever) one month back. After 20 days reason for fever was diagnosed to be pleural tuberculosis. Is there a possibility my wife be infected wit tb ? either latent or active tb ? suppose my wife have latent tb will it affect baby in any way ? Please clarify what action to be taken

Thanks for posting on HCM
TB is contagious and mostly affect immune-compromised people even though healthy people could also be affected.The most contagious TB is pulmonary.Extrapulmonary TB is not contagious.In your case, pleural TB is extrapulmonary. Extrapulmonary TB (plerura, glands, bone, peritoneal..) is possible with lungs free from the infection.You will however need to be isolated for say 3 weeks with anti-TB drugs initiated since a patient on treatment is no longer contagious.
The chances of your wife being infected are low even though can not be completely ruled out.I will suggest she gets tested for TB.Even if no symptoms, she should take a chest x-ray and a tuberculin skin test to see if she has been exposed to TB.If any arguments in favor of TB infection, she will need to start treatment early so that the baby will not have any problem.Most anti-TB drugs are safe in pregnancy.
Hope this will help
Best wishes

How contageous is it? Amelia is 5 yrs old, is underweight, thin, was having night sweats and all the glands in her neck are like golf balls. on the skin test there is a positive reaction. She has a brother, and a 4 month old sister. Her father had TB 3 years ago. How contageous is it. We have taken a sample of sputum of both father and mother and sent it for testing. She has been playing with other smaller children, and I am concerned that they could have been infected.
