Overview
- The National Epidemiological Bulletin recorded 55,183 syphilis diagnoses in 2025, a 71% rise over the 2020–2024 baseline, concentrated in people aged 15–39.
- In Salta, 1,602 cases were confirmed in 2025, mostly among 20–39-year-olds, with 56.1% women and seasonal peaks in October and December centered in the province’s central area.
- Reported congenital syphilis notifications fell in 2025 versus recent years, but officials flag those figures as provisional pending validation.
- Infectious-disease specialists link the surge to reduced condom use, substance-associated sexual encounters, and reliance on HIV PrEP, which does not prevent bacterial STIs.
- Authorities promote routine screening, including rapid tests and prenatal checks, and stress that free, highly effective penicillin-based treatment is available for patients and partners.
