The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS. In 2019, about 208 000 people died of HIV-associated TB. People at high risk of developing TB will soon get access to a once-weekly pill that prevents TB bacteria from developing into a contagious case. It can be assumed that this category of patients has an increased risk of developing tuberculosis in the future. However, people with weakened immune systems are at a greater risk for developing active TB right away. Anti-TB medicines have been used for decades and strains that are resistant to one or more of the medicines have been documented in every country surveyed. Tuberculosis (TB) is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. TB is present in all countries and age groups. Am I at risk?
