<s>[INST] Is TB a growing concern for people working in the HIV field? [/INST] Yes. It is estimated that one-third of people living with HIV worldwide are co-infected with
TB. People with HIV are up to 50 times more likely to develop TB in a given year than
HIV-negative people.
Another growing concern is the development of drug-resistant strains. These strains can
be created by inconsistent and inadequate treatment practices that encourage bacteria
to become tougher. The multidrug-resistant strains are much more difficult and costly to
treat and multidrug-resistant TB (MDR-TB) is often fatal. Mortality rates of multidrugresistant TB are comparable with those for TB in the days before the development of
antibiotics. For more information on drug resistant TB see the section on extensively
drug resistant TB (XDR-TB) at the end.  Source: UNAIDS. Link: https://data.unaids.org/pub/factsheet/2006/tb_hiv_qa.pdf. Field: Lung Disease. Disease: Tuberculosis </s>
