RESUMEN
@#Tuberculosis remains a major global health problem with 10.4 million incident cases in 2016. Although Mycobacterium tuberculosis is the causative agent, many environmental factors play a role in disease progression. Several respiratory hazards including smoking and indoor air pollution were suggested to increase the risk of tuberculosis, but only fewer studies has been conducted on the association between ambient air pollution and tuberculosis. </br> Mongolia is a one of the seven TB high burden countries in the WHO Western Pacific Region. In 2017, there were 3779 TB cases in Mongolia. Most of them were smear positive pulmonary cases. Mongolia achieved the regional WHO targets for finding and curing TB. Currently, case detection and treatment success rates have reached 72% and 84.0%, respectively.</br> Air pollution is hard to escape no matter how rich an area you live in, it is all around us. Also, air pillution is incerasingly serious problem in Mongolia. Globally it is estimated that 9 out of 10 breathe polluted air and about 7 million deaths are attributed to air pollution. It is estimated that 91% of the world’s population lives in area where the World Health Organization (WHO) Air Quality Guidelines are not met. </br> In addition, children are highly affected by air pollution because their lungs are still developing and the air pollution can interfere with this biological process, their bodies are less able to metabolize, detoxify and excrete the toxins contained in the air pollution. Many epidemiological and ecological studies were done in Mongolia toward to air pollution and health. However, it is still not clear how much indoor and ambient air pollution can cause to TB incidence in Mongolia.
