Human coronavirus data from four clinical trials of masks and respirators
COVID-19 is caused by SARS-CoV-2, a beta-coronavirus which is genetically similar to SARS-CoV. Seasonal alpha- (NL63, 229E) and beta- (OC43, HKU1) coronaviruses cause common colds, croup and bronchiolitis. The transmission modes of human coronaviruses are similar, thought to be by droplet, contact and sometimes airborne routes (Van der Hoek, 2007; Wu and McGoogan, 2020). Currently, the WHO recommends surgical masks for healthcare workers (HCW) providing routine care to a COVID-19 patient (WHO, 2020), whilst the US CDC (US Centers for Disease Control, 2020a) and ECDC (US Centers for Disease Control, 2020b) recommend respirators.
