11 Facts About Tuberculosis
- Tuberculosis (TB) is contagious and spreads through the air; if not treated, each person with active TB infects on average 10 to 15 people a year.
- There were 9.4 million tuberculosis cases in 2009, but the TB death rate has fallen 35% since 1990.
- 1 in 10 people infected with TB bacteria will become sick with active TB in their lifetime; people with HIV are at much greater risk.
- 1.7 million people died from TB in 2009 including 380,000 people with HIV, equaling to 4,700 deaths per day.
- TB is a leading killer of people with HIV. People who are HIV-positive and carry the TB germs are up to 50 times more likely to develop active TB in their lifetime.
- TB is a disease of poverty. The vast majority of TB deaths are in the developing world, with more than ½ of all deaths occurring in Asia.
- People with active TB disease must complete a course of treatment for six months or more.
- Spotty monitoring and drug intake and poor health infrastructure have encouraged drug-resistant strains of TB to thrive.
- Multi-drug resistant TB (MDR-TB) and Extensively drug-resistant TB (XDR-TB) are forms of tuberculosis that are extremely difficult to treat since they fail to respond to traditional drugs.
- Drug-resistant TB thrives and spreads quickly in prisons and hospitals because of close quarter, poor sanitation, lack of ventilation and poor protective measures.
- Just one mismanaged TB patient (not taking meds properly and/or not quarantined) can cause an outbreak in a contained environment, like a hospital or prison.
