Comparison of breath-guards and face-masks on droplet spread in eye clinics.

Introduction: COVID-19 has impacted ophthalmic care delivery, with many units closed and several ophthalmologists catching COVID-19. Understanding droplet spread in clinical and training settings is paramount in maintaining productivity, while keeping patients and practitioners safe.

Objectives: We aimed to assess the effectiveness of a breath-guard and a face mask in reducing droplet spread within an eye clinic.

Detection of dental fomites using topical fluorescein.

Background Thorough disinfection of dental facilities is of paramount importance during the COVID-19 pandemic. Patients, clinicians, students and nurses can all be infected by aerosols and dental droplets bearing COVID-19. However, droplets are transparent and often microscopic, so are difficult to detect in clinical practice.
