Partner notification is a key part of STI care but uptake in many LMIC settings is low.
Our RCT in Zimbabwe tried to improve uptake via financial incentives.
Results out in Lancet Global Health.

Detection and characterisation of Xpert CT/NG assay Neisseria gonorrhoeae diagnostic escape mutants, England, June 2025
We report the timely detection of a strain of Neisseria gonorrhoeae which was confirmed as a diagnostic escape mutant on the Cepheid Xpert CT/NG assay in England in June 2025. The reason for assay failure was a likely recombination event with Neisseria meningitidis, which removed both assay target sites. Seven historical putative Xpert CT/NG assay diagnostic escape mutants were also identified following subsequent in silico screening of gonococcal genome collections, but currently there is no evidence of widespread circulation.
