Background:

Tuberculosis (TB)/HIV coinfection has a high mortality rate.

Aim:

To describe socio-epidemiological characteristics of tuberculosis (TB)-HIV coinfection, and aspects associated with its prevalence, from 2005 to 2018.

Material and Methods:

Analysis of the registry of the tuberculosis control and elimination program of three public health services of metropolitan Santiago.

The variables considered were:

TB/HIV coinfection, age, sex, location of tuberculosis, bacteriological confirmation, incarceration, commune of residence, country of origin and effectiveness of the tuberculosis therapy.

Results:

We analyzed 7507 TB cases, of whom 12% corresponded to cases of coinfection. The number of coinfections doubled in the last 6 years. In 2018, 45% of coinfection cases occurred in migrants. Of the total cases evaluated, 53% were successfully treated and 28% died.

Conclusions:

The remarkable increase in TB/HIV coinfection, urgently demands new prevention and control strategies, aimed at the most vulnerable groups.
