- In Barcelona, time from HIV diagnosis to treatment has shortened, but time from infection to diagnosis still needs reduction.
Why this matters
- Barcelona sees many newcomers either coming to stay or passing through, and access to services can differ for locals vs visitors and newcomers.
- Over 4 measurement periods (since 1997), the yearly rate of new infections among new diagnoses increased from 1% to 8% (P<.001>
- Over that same period, the proportion of men who have sex with men (MSM) increased from 62% to 89% (P<.001>
- Mean time from infection to diagnosis was similar across time periods (53.6 [interquartile range (IQR) 50-57] days).
- Mean time from infection to treatment decreased from 575 (IQR, 467-683) to 471 (IQR, 394-549) days (P<.001 and was similar between newcomers locals.>
- A cluster of transmission was identified and included 1 in 2 of recently infected patients, and 92% were MSM.
- Route of transmission rates changed from intravenous drug use in 24% of cases to less than 1% in most recent period (P<.001>
- Prospective, single-center cohort study, all patients (n=364) with acute/recent HIV infection (less than 180 days), 1997-2015.
