Tuberculosis (TB) is a disease caused by mycobacterium tuberculosis which is easily transmitted through the air when an infected person speaks, sneezes, laughs, sings or coughs. Airborne particles then get inhaled whereby they will multiply in the exposed person's lungs.
Anyone can contract TB. It thrives mostly among people living in poverty, communities and marginalized groups like refugee camps and migrants. Malnutrition, poor sanitation, and housing compounded with other factors like tobacco and alcohol use affect the vulnerability to TB.
