If they have latent TB, which cannot be spread
to others, they are at risk for the infection becoming an active disease, which
can be spread to others. Active TB in the lungs also is more likely to spread
to other parts of the body (extrapulmonary TB) in people who have HIV infection
than in people who do not have it.
HIV infection comes in three stages. The first stage is called acute infection or seroconversion, and it typically happens within two to six weeks after exposure or becoming infected. This is when the body's immune system puts up a fight against HIV. The symptoms of acute infection look similar to those of other viral illnesses and are often compared to those of the flu. The symptoms may last a week or two and then completely go away as the virus goes into a non-symptomatic stage.

skin tests sometimes do not detect an infection in

lung infections common in AIDS, such as Pneumocystispneumonia, may mask the signs of TB infection on chest X-rays.
Active TB can be the first sign of an HIV infection or

When people are diagnosed with HIV, they also should have a
test for TB.
Active TB may speed the progression of HIV in people who are
infected with both diseases and also may increase their risk of dying from the
HIV infection. People who have both diseases may be at increased risk for
multidrug-resistant TB. For these reasons, it is
important to promptly
treat people who have HIV infection and TB. With
treatment, latent and active TB usually can be cured in people who have HIV or
