Description
Issa Abu-Dayyeh and colleagues chart, in a 2026 laboratory study, fifteen years of syphilis epidemiology in Jordan, a priority infection targeted for global elimination by 2030. Data came from 25,630 adults tested at a major diagnostic laboratory network between 2010 and 2025, using two blood tests that together indicate past or present infection.
Overall prevalence of ever testing reactive was 0.9 percent, and only 0.08 percent among people screened for visa medicals. One test type was reactive in half a percent of all tested, and most of those confirmed on the second test within a month. Reactivity ran far higher in outpatient, doctor-referred, and laboratory-referred testing than in visa screening, while sex, region, insurance, and year showed no significant links. Incidence stayed under one case per thousand person-years, with no decline over the period.
