Ivermectin as Pre-exposure Prophylaxis for COVID-19 among Healthcare Providers in a Selected Tertiary Hospital in Dhaka – An Observational Study

Abstract

Introduction: While multiple vaccines are undergoing clinical trial across the globe, we yearn for an FDA approved drug to protect us from the devastating pandemic for the time being. This study aims to determine the effectiveness of Ivermectin when administered as pre-exposure prophylaxis for COVID-19. Method: An observational study, with 118 healthcare providers who were enrolled purposively, was conducted in a tertiary hospital in Dhaka from May 2020 to August 2020. The subjects were divided into experimental and control groups; and the experimental group received an oral monthly dose of Ivermectin 12mg for 4 months. Both groups were exposed to COVID-19 positive patients admitted in the hospital during the course of study. The symptomatic subjects were evaluated by physical examination, COVID-19 RT-PCR and/or HRCT of chest. Differences between the variables were determined using the Chi-square test and the level of statistical significance was reached when p<0.05. Result: 73.3% (44 out of 60) subjects in control group were positive for COVID-19, whereas only 6.9% (4 out of 58) of the experimental group were diagnosed with COVID-19 (p-value < 0.05). Conclusion: Ivermectin, an FDA-approved, safe, cheap and widely available drug, should be subjected to large-scale trials all over the world to ascertain its effectiveness as pre-exposure prophylaxis for COVID-19.
