HIV testing of patients diagnosed with tuberculosis increased in Denmark during the period from 2007 to 2009.

We examined the trends of HIV testing among patients notified with TB in Denmark during a 3-year period from 2007 to 2009. We were able to obtain HIV testing status for 96%. There was a significant increase of patients examined for HIV infection during the 3-year period. HIV prevalence among HIV-tested TB patients in Denmark is much higher than in the average population. It seems there is an increasing awareness in Denmark towards testing TB cases for HIV co-infection.
