Overview
- The latest national bulletin shows 2025 syphilis totals of 46,613 confirmed cases (55,183 notifications), a rise of roughly 64–71% versus the 2020–2024 median.
- Infections in pregnant people reached 11,261 confirmed in 2025, about 15% above the recent five‑year median, while 1,033 congenital confirmations were reported with explicit caution that these figures are provisional.
- Initial 2026 surveillance remains high: week 1 recorded 1,092 confirmed cases and 1,247 notifications in the general population, exceeding the 2021–2025 median; 317 confirmations were logged in pregnant people.
- Experts and the bulletin attribute the rise to reduced condom use, reinfections, changing sexual practices and risk perception, and broader reporting and testing that can elevate recorded counts.
- Public‑health responses emphasize rapid and dual testing, strengthened prenatal screening and prevention messaging, with municipal programs such as Rosario’s expansion of on‑site rapid tests.
