My mother just returned from a trip to Constantsa, Romania where she visited a relative who has been diagnosed with tuberculosis and has been on treatment for about 2 years. She spent a few days living in the same apartment with him. Upon returning to the US yesterday, it has become evident to me that I should be concerned about my child's health. She is almost 7 years-old in good health, however, her immune system is not fully developed. She has not continued vaccinations since she was 4 years-old. She was never given the BCG vaccination as they did in eastern Europe. All my family members have been vaccinated with BCG. Knowing that tuberculosis from eastern-European/Russian sources have been growing and travelling all over the world and are now resistant strains, I am seriously concerned about my daughter's health when she comes in contact with my mother.
My question is: Is it safe to have my child near and in the same room as my mother. If she shows no symptoms, cold she still be a carrier even if she was vaccinated? As a precaution, should I keep them away from each other?
