Health authorities in Slovakia reported a historic peak in syphilis cases in July 2026, marking the highest number recorded since systematic monitoring began. The increase is part of a continental rise, with Europe logging roughly 46,000 cases in 2024—more than double the count from a decade earlier. Officials attribute the surge to changes in sexual behavior, expanded testing, and improved diagnostics, and they emphasize condom use and partner screening to curb transmission. Within the same week, Bulgaria’s National Center for Infectious and Parasitic Diseases announced a 30‑40% rise in syphilis infections compared with the previous year, alongside a three‑fold increase in gonorrhea cases. The director highlighted the need for better public health information and safe‑sex practices while also noting related vector‑borne concerns such as West Nile fever and Lyme disease in the region. Together, the reports illustrate a broader Eastern European trend of escalating sexually transmitted infections. ## Timeline ### 2026-07-30: Bulgaria sees 30‑40% rise in syphilis and gonorrhea cases, warns Iva Hristova Bulgaria reports a 30‑40% rise in syphilis and a three‑fold increase in gonorrhea, warns health director Iva Hristova, and highlights West Nile fever cases in North Macedonia and 222 Lyme disease cases domest 3 sources. https://clstr.news/cluster/bulgaria-sees-3040-rise-in-syphilis-and-gonorrhea-cases-warns-iva-hristova ### 2026-07-25: Slovakia sees record rise in syphilis cases Slovakia records a historic high in syphilis cases amid a Europe-wide surge, warning of silent spread, serious health risks, and urging testing and safe sex. 3 sources. https://clstr.news/cluster/slovakia-sees-record-rise-in-syphilis-cases --- Cite as: Eastern Europe syphilis surge.
