How does infection with TB affect the HIV/AIDS scenario?
Ans. TB shortens the survival of patients with HIV infection, accelerates the progression of HIV to AIDS as observed by a six- to seven-fold increase in the HIV viral load in TB patients and is the cause of death for one out of every three people with AIDS worldwide. Effective treatment using DOTS not only prolongs the survival of patients living with AIDS, but also improves their quality of life. Q. What is the impact of HIV on the epidemiology of TB? Ans. HIV fuels the TB epidemic. The rate of progression to active TB is 10 to 30 times higher among individuals infected by both TB and HIV than among those infected only with TB. This is because people with HIV infection have suppressed immunity and hence chances of reactivation of dormant TB bacilli is many fold higher in them than among those without HIV. Also, due to low immunity, natural infection may rapidly lead to TB disease. Moreover HIV infection may also contribute to an increase in drug resistance. Increased TB cases in HIV-i
