Trachoma is endemic in Kenya. Since baseline trachoma surveys in 2004, a concerted programme has been undertaken to reduce the prevalence of disease. Here, we report on trachoma prevalence surveys carried out between 2017 and 2020 after interventions were implemented in some areas for trachoma elimination purposes.

A total of 48 cross-sectional population-based trachoma prevalence surveys were conducted in 39 evaluation units (EUs; covering 45 subcounties) of Kenya between 2017 and 2020. Thirty EUs were surveyed once and nine EUs were surveyed twice over this period. Individuals ≥ 1 year old were assessed for trachomatous inflammation–follicular (TF), trachomatous inflammation–intense (TI) and trichiasis. Data were collected on household access to water, sanitation and hygiene (WASH).

A total of 147,573 people were examined. At the end of 2020, in the 39 EUs surveyed, the prevalence of TF in 1–9-year-olds was ≥5% in 11 EUs and the prevalence of trichiasis unknown to the health system in individuals aged ≥15 years was ≥0.2% in 25 EUs. A small minority of households (median <50% for all indicators) had access to improved WASH facilities.

Kenya has made excellent progress towards elimination of trachoma as a public health problem. However, there is more work to do. Between one and three rounds of antibiotic mass drug administration are required in 11 EUs. Sustained investment in surgical provision, continued TT case-finding, promotion of facial cleanliness and environmental improvement are required throughout the surveyed area.

Funding

Surveys in 2017–19 were funded by the Queen Elizabeth Diamond Jubilee Trust (which consolidated funding multiple sources including Lions Clubs International Foundation) through implementing partners in Kenya including Sightsavers, the Fred Hollows Foundation, CBM, Operation Eyesight and AMREF Health Africa (TG001). Surveys in 2019–20 were funded by the UK Government’s Department for International Development and the Accelerate programme (300576). Surveys in late 2020 were supported by the Accelerate program which included funding from the Bill & Melinda Gates Foundation, Children’s Investment Fund Foundation, The ELMA Foundation, UK aid and Virgin Unite. RB’s salary was funded by the Fred Hollows Foundation. AWS is a staff member of the World Health Organization. Core Tropical Data funding was provided by the International Trachoma Initiative; Sightsavers; and RTI International through the United States Agency for International Development (USAID) Act to End NTDs | East programme.
