ABSTRACT

SARS-CoV-2 is dispersed from patients by talking, coughing, and sneezing. The generated microdroplets aerosols can travel up to 8m, stay suspended for long periods, and preserve viral infectivity for median of 2.7h. An unprotected person exposed to this cloud might inhale a considerable amount of infectious viral doses, which will attach to the ACE two receptors at the respiratory system epithelial, resulting in infection. N95 respirators and surgical masks block 95% and 50%-60%, respectively, of inhalable particles and protect the wearer from infection. Surgical masks and N95 without exhalation valve protect both the wearer and the environment from carriers and sick people. The highest risk of infection is in closed and unventilated spaces. Any kind of respiratory protection will mitigate risk of infection, including cloth masks, but none will protect if there is no good seal around the face. Medical staff and laboratory workers will benefit most by wearing NIOSH approved N95 respirators, while adhering to guidelines and instructions for keeping the seal around the face. N95 with exhale valve protects the wearer but not others. Face shields with combination of masks or respirators provide additional protection from infection, by reducing ocular exposure or contamination of masks or hands, as well as by diverting movement of air around the face. © 2023 Elsevier Inc.
