Introduction: HIV infection/AIDS continue to be a highly relevant global public health problem. Colombia is one country, in Latinamerica, with a considerable epidemiology, with high incidence municipalities; among those is included Pereira. Materials and methods: Assessment of main epidemiological indicators (estimations of incidence, mortality and lethality) of HIV infection/AIDS, period 1998-2011, Municipality Pereira, Risaralda, Colombia. Results: During the period a total of 1471 cases were recorded (mean 105.1±27.6/year, range 51-159); increasing (r2=0.3028; p=0.0415), specially between 20062011 (r2=0.845; p=0.0095). Incidence oscillated between 11.8 (2001) to 34.6 (2011) cases/100,000 pop (95%CI 29.0-40.0), without a significant increase between 1998-2005 (r2=0.0351; p=0.6567), and increasing significantly between 2006-2011 (r2=0.8318; p=0.0113). A total of 631 deaths were recorded (mean 45.1±8.9/year, range 32-64), no significant variation between 1998-2005 (r2=0.042; p=0.6262); from 2006-2011 were significantly reduced (r2=0.7016; p=0.0374). Mortality oscillated from 7.0 (2010) to 14.3 (2006) deaths/100,000 pop (95%CI 11.0-18.0), significantl decreasing between 2006-2011 (r2=0.7251; p=0.0314). Lethality (CFR) in the period oscillated from 21.9% (2010) to 88.2% (2001) (95%CI 8.41-98.06). Discussion: Although HIV/AIDS incidence is increasing, lethality and mortality are progressively decreasing. This could be related to multiple factors that include a better diagnostic and therapeutic coverage, higher access to the health care system, more information availability, as well appropriate and skilled multidisciplinary management. However, at promotion and prevention there are still great challenges to achieve, that include more communitary participation in the processes of information access, epidemiological surveillance, quality assessment at the use of health care services related to HIV/ AIDS, among others.
