Does calcification of old tuberculosis affect going abroad?

Tuberculosis is an airborne infectious disease that seriously affects human health, and it is quite common in China in recent years. Many people don't have typical symptoms such as low fever, cough and emaciation after infection, and they don't know until X-ray shows lung calcification. The infection rate of tuberculosis in Canada is very low, so tuberculosis is one of the serious diseases that Canadian immigrants attach importance to in physical examination.

However, this does not mean that those who are unfortunately infected with tuberculosis can never immigrate or study in Canada. Usually they need sputum culture for three days in a row. If the result is negative, it proves that there is no living Mycobacterium tuberculosis in their sputum, which is not contagious to the public, and X-rays can be rechecked three months later to prove that their tuberculosis focus is stable and there is no recurrence.

Because sputum culture takes 8 weeks to produce results, if calcification is found in the initial examination, sputum should be taken immediately for culture, and the results can be produced when the Immigration Bureau informs you to check the project further two months later, saving two months. In case the sputum culture results are positive for Mycobacterium tuberculosis, or X-ray shows active pulmonary tuberculosis, you can use special drugs for 3-9 months, and you can also go abroad after sputum culture turns negative. In this way, although the patient spends more time and money, it is beneficial to the health of himself and others and has no worries. On the contrary, if you are just lucky, you may plant a curse. Because calcification of tuberculosis always exists, once the immigration department rechecks the X-ray, it will find out and cancel its visa. /zd/lx
