The differences between Tuberculosis and HIV
HIV is a virus; TB is a bacteria.
- HIV weakens the immune system; TB needs a weakened immune system in which to flourish.
- Once TB treatment is completed, it is stopped; ARV’s are taken for the rest of one’s life.
The similarities between Tuberculosis and HIV
- HIV weakens the immune system. TB also weakens the immune system.
- Treatment and prevention of both diseases require healthy nutrition, healthy lifestyle choices and the practice of good hygiene.
- The HIV virus can become drug resistant – TB can also become drug resistant.
The dangers of the combination
- An HIV positive person is 10 times more likely to develop TB.
- HIV shortens the time between infection of TB and activation of the TB disease.
- The mortality rate from TB is 4 times higher in people who are infected with HIV.
- TB can shorten the time for HIV to become final stage AIDS.
- HIV positive people have more chance of developing extra pulmonary TB
- TB diminishes CD4 cells while increasing viral load.
- The presence of HIV reduces the accuracy of a TB diagnosis
- There is a higher chance of TB treatment failure.
- Being HIV positive might cause an adverse reaction to TB medication.
- Drug interactions may occur between TB drugs and ART.
- TB medication, i.e. Rifampicin, may decrease the effectiveness of ARV’s if taken in combination. ARV’s are therefore adjusted to take this into account.
- The development of multi-drug resistance to TB medication is greater because side effects from TB drugs may be more severe.
