Abstract
The global outbreak of SARS-Cov-2 (called Covid-19) has claimed many lives, with currently over 59.95 million confirmed cases of infected persons and over 1.4 million deaths worldwide. Spray aerosols used to disinfect areas, surfaces, and objects are crucial to preventing and protecting people against Covid-19. This paper presents and examines various available and approved materials to formulate spray aerosols for disinfection against Covid-19. The formulations are discussed based on the active ingredient and the possible contact time. The virus can be inactivated. The major groups of spray aerosols discussed include quaternary ammonium-based sprays, hydrogen peroxide-based sprays, alcohol-based sprays, acid-based sprays, sodium-based sprays, and other formulations, some of which are recommended by the US Environmental Protection Agency. Information presented here could benefit governments, policymakers, communities, researchers, health workers, and the general public during this pandemic and beyond.
