To eliminate trachoma: Azithromycin mass drug administration coverage and associated factors among adults in Goro district, Southeast Ethiopia

Abstract

Background Globally, although effective prevention strategies and treatment are available, trachoma remains the major cause of infectious loss of sight. Trachoma is a predominant neglected disease in Ethiopia, and there is a 40.4% prevalence of active trachoma in the Goro district, Southeast Ethiopia. World Health Organization (WHO) recommends azithromycin mass treatment of at least 80% coverage to eliminate trachoma, even though the coverage of azithromycin mass treatment has not been studied yet in depth. Thus, this study aimed to assess the coverage and factors influencing azithromycin mass treatment uptake among adults in Goro district, Southeast Ethiopia. Methods A community-based cross-sectional study was conducted from April 1st to April 30th, 2021 among all adults aged 15 years old and above. The multistage sampling technique was used to select 593 study respondents. A structured interviewer-administered questionnaire was used. Data were entered into Epi-Data version 3.1 and analyzed using SPSS version 23.0 software. Descriptive analysis and binary logistic regression analysis were used to analyze the data. Adjusted odds ratios (AOR) along with a 95% confidence interval (CI) and p-value Results/Principal findings Five hundred and seventy eight study participants with a 97% response rate were included. The proportion of azithromycin mass drug administration coverage was found to be 75.80%; 95% CI: (72%-79%) in this study. Having better knowledge about trachoma (AOR = 2.36; 95% CI: 1.19–4.70), having better knowledge about azithromycin mass treatment (AOR = 4.19; 95% CI: 2.19–7.98), being educated (AOR = 7.20; 95% CI: 1.02–51.09), a campaign conducted at the quiet time (off-harvesting/planting season) (AOR = 6.23; 95% CI: 3.23–11.98), heard about the serious adverse effect from others (AOR = 0.25; 95% CI: 0.10–0.59) and being a volunteer to take azithromycin in the next campaign (AOR = 5.46; 95% CI: 2.76–10.79) were significantly associated with azithromycin mass drug administration coverage. Conclusions/Significance The proportion of azithromycin mass treatment coverage of this study was lower than the WHO minimum target coverage. Thus, strengthening awareness, enhancing azithromycin mass trachoma treatment messages, and conducting campaigns off-season outside of harvesting and planting time should be prioritized in the future to meet the 2030 Sustainable Development Goal (SDG) target. Author summary Trachoma is the leading cause of infectious loss of sight worldwide. The mass treatment with azithromycin has been used in the prevention and treatment of chlamydia trachomatis and is recognized as a potentially vital and important public health strategy for the control of trachoma disease and other co-infections. Oral azithromycin is easy to administer and offers a better resolution for controlling blinding trachoma for long periods. The proportion of azithromycin mass treatment coverage in the Goro district was lower than the WHO minimum target. Having better knowledge about the trachoma and azithromycin mass treatment and being educated were some of the factors positively affecting the uptake of the azithromycin mass treatment. Hearing serious adverse effects of the drug from other people and campaigns conducted during harvesting or seeding time were some factors negatively affecting the coverage of azithromycin mass treatment in the current study.
