And the disease spreads from one person to another through tiny droplets released into the air via coughs and sneezes.
Every year on March 24, World Tuberculosis Day is observed all over the globe. It is a worldwide event, designed to build public awareness about the global epidemic of tuberculosis (TB) and efforts to eliminate the disease.
Here are some factors that increases the risk of developing the disease:
Infection with HIV, the virus that causes AIDS and weakens the immune system
Low body weight
Head or neck cancer, leukemia
Silicosis, a respiratory condition caused by inhaling silica dust.
People who live with or care for someone with active TB
Health care workers who treat people with a high risk of TB
But the disease can be prevented through adequate ventilation and limited contact with patients.
