CDC HIV and TB Fact Sheet
The Centers for Disease Control and Prevention (CDC) has
issued a revised fact sheet on tuberculosis in people
(TB) is common among HIV
positive people, especially in resource-limited countries.
It is the leading causes of mortality for people with HIV/AIDS
worldwide, accounting for nearly 1 in 4 deaths.
bacteria can live in the body without causing symptomatic
illness -- known as latent TB infection -- but can become
active if the immune system is weakened. According to the
CDC, HIV positive people with latent TB are 20 to 30 times
more likely than HIV negative people to develop active TB
is less common in the U.S., with about 4% of Americans (HIV
positive and negative combined) -- or approximately 13 million
people -- being infected. There were 554 deaths due to TB
in 2007. But prevalence is unevenly distributed in the population,
with blacks making up about 60% of HIV/TB coinfected people.
The CDC recommends that all people newly diagnosed with HIV
should be tested for TB as soon as possible, and people living
with HIV and at risk for TB exposure should be tested annually
to detect latent infection.
People with active TB disease require a combination of medications
for treatment, while people with latent infection can take
less intensive regimens to prevent activation. The emergence
of multi-drug resistant and extensively drug resistant bacteria,
however, can compromise treatment effectiveness
