RESUMO
BACKGROUND: SARS-CoV-2 is the virus responsible for the current global pandemic, COVID-19. Because this virus is novel, little is known about its sensitivity to disinfection. METHODS: We performed suspension tests against SARS-CoV-2 using three commercially available quaternary ammonium compound (Quat) disinfectants and one laboratory-made 0.2% benzalkonium chloride solution. FINDINGS: Three of the four formulations completely inactivated the virus within 15 s of contact, even in the presence of a soil load or when diluted in hard water. CONCLUSION: Quats rapidly inactivate SARS-CoV-2, making them potentially useful for controlling SARS-CoV-2 spread in hospitals and the community.

The rubella epidemic of 1964-1965 resulted in the birth of a group of children with defects of vision, of hearing or of the heart. In this study of cases known to five Los Angeles agencies, it was found that about half of those affected have more than one defect. Findings demonstrate a need for more sensitive communicable disease surveillance and for the development of services for the multiple handicapped child.
