Title: Association between syphilis seroprevalence and age among blood donors in Southern China: an observational study from 2014 to 2017 Document date: 2019_11_2
ID: ubnv0fdw_117
Snippet: Among 733 donors with active infection, a TRUST titre of 1∶1 accounted for the largest proportion (41.7%), followed by a titre of 1∶2 (24.1%). About 27.0% had a TRUST titre of ≥1∶8. The distribution of TRUST titres was varied among the age groups (Figure 3) . Patients aged ≥45 years comprised a large proportion of low titres at 1∶1 and 1∶2, and the proportion of high titres was only 16.3%, which was much 1 2 3 4 5 6 7 8 9 1.....

More than 95% of people who received HIV testing services have undergone free syphilis testing. 30 Referral, treatment, and follow-up services would be provided to those diagnosed with syphilis. In Shenzhen, more than half of VCT sites are set in community health service centres, where a separate room is arranged for counselling and testing service.
