Background & AimsEgypt has a major HCV burden and a well established treatment programme, with an ambitious goal of HCV elimination. Our aim was to assess the impact of a comprehensive HCV prevention, test and treat programme on the incidence of new HCV infections in 9 villages in rural Egypt.MethodsAn HCV "educate, test and treat" project was implemented in 73 villages across 7 governorates in Egypt between 06/2015 and 06/2018. In 2018, in 9 of the villages we re-tested individuals who originally tested HCV antibody (HCV-Ab) and HBsAg negative using rapid diagnostic tests (RDTs); confirmatory HCV RNA testing was performed for positive cases. The incidence rate per 1,000 person-years (py) was calculated, and risk factors for incident HCV infections assessed through an interviewer-administered questionnaire in 1:3 age- and gender-matched cases and controls.ResultsOut of 20,490 individuals who originally tested HCV-Ab negative in the 9 villages during the 2015-2016 implementation of the "educate, test and treat" programme, 19,816 (96.7%) were re-tested in 2018. Over a median of 2.4 years (IQR 2.1-2.7), there were 19 new HCV infections all of which were HCV RNA positive (incidence rate 0.37/1,000 py) (95% CI 0.24-0.59). Compared to a previous estimate of incidence in the Nile Delta region (2.4/1,000 py) from 2006, there was a substantial reduction in overall incidence of new HCV infections. Exposures through surgery (odds ratio 51; 95% CI 3.5-740.1) and dental procedures (odds ratio 23.8; 95% CI 2.9-194.9) were significant independent predictors of incident infections.ConclusionsThis is the first study to show a substantial reduction in incidence of new HCV infections in a sample of the general population in Egypt following attainment of high testing and treatment coverage. New infections were significantly associated with healthcare-associated exposures.Lay SummaryEgypt has a major national HCV testing and treatment programme with the goal of eliminating HCV infection. We assessed the impact of a comprehensive HCV prevention, test and treat programme in 73 villages that achieved high coverage of testing and treatment on the subsequent incidence of new HCV infections in nine of the villages. We re-tested people who were previously HCV antibody negative and found that the rate of new HCV infections was greatly reduced compared to previous estimates. We also found that exposure through surgery and dental procedures were associated with these new infections. This highlights the importance of continued strengthening of infection control and prevention measures, alongside treatment scale-up.Copyright © 2020 World Health Organization.
