My mum is with her and she had TB around 10 years ago, but she is totally cured. X-rays and cultural examinations were negative. i am wondering is this swelling realated to TB infection. My daughter had bad cold last week, but no cough . Wheather TB spread even if it is completely cured? please answer me ASAP.

Hi,
Your daughter has had a delayed granulomatous reaction to BCG which most of the time is not due to active tuberculosis but just an allergy to the protein in the BCG vaccine.This lesion usually needs no treatment however if its too large and formed an abscess then surgical exicision may be done.Chances of recurrence of TB might happen in immunocompromised patient whose immunity is poor so if your mother is healthy then be assured she has no TB at present.However i would suggest that you get your daughter examined by her docter so that he could run few investigation to rule out active infection.

Hi,

Thanks for writing to health care magic.

There cannot be a risk of transmission if a person is completely cured of tuberculosis.

So do not worry that your mother who had tuberculosis 10 years before and treated can transmit that to your baby now.

I request you to consult your doctor if the swelling is increasing in size.

Hope this helps.
Take care.
