Nano-treatment of HEPA filters in COVID-19 isolation rooms in an academic medical center in Saudi Arabia.

ABSTRACT:

Introduction

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has spread globally. The major reservoir for SARS-CoV-2 transmission remains controversial, with the airborne route remaining a possible transmission vehicle for carrying the virus within indoor environments. This study aimed to detect contamination of SARS-CoV-2 in high-efficiency particulate air (HEPA) filters within hospital isolation rooms of confirmed COVID-19 patients, exploring the role of nano-treatment of these filters with silver and titanium dioxide nanoparticles (Ag/TiO₂ NPs).

Materials and methods

We investigated the effectiveness of Ag-NPs/TiO₂-treated HEPA filters in the air of rooms occupied by patients with confir
