Among 180 patients tested for HIV during this time period, 18(10%; 95% CI: 6%\u201315%) had a new diagnosis of HIV, which is up to 50 times greater than the national 0.19% prevalence of people living with HIV in Mexico. Women (aOR: 3.5, 95% CI: 1.8\u20136.7), people who use drugs (aOR: 5.2, 95% CI: 2.1\u201313.1), and people with another sexually transmitted infection (aOR: 3.3, 95% CI: 1.6\u20136.7) had significantly greater risk for HIV.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our data identified a niche population in Tijuana with substantially higher risk for HIV acquisition and transmission compared to the general public.
