My mother is being investigated for kidney tuberculosis. I understand that this in itself is not infectious but that there is likely to have been a primary lesion in the lungs. I am on Methotrexate for Rheumatoid Arthritis and because of lowered immune status, I am interested to know if it is sensible to visit at present?. I know that this may sound very selfish but would like to be certain.
Thank you meantime
Kidney tuberculosis is not infectious, but, as you've been told already, tuberculosis of the lung can be present at the same time with tuberculosis of kidney.
If the lung lesions were confirmed (chest x-ray, sputum analysis), she is infectious for her environment cause the tuberculosis bacillus (germ) is transmitted only through air (not through urine).
To become infected, a person usually has to have frequent exposure to someone with active TB. For example, spending several hours a day with a person with active TB would put you at risk of infection.
Weak immune system, is the most important risk factor for TB infection and TB disease.
