Summary

Since its first identification in Wuhan, China in November-December 2019, the novel coronavirus (SARS-CoV-2) has been implicated in the COVID-19 global pandemic. Similar to a previous coronavirus (SARS-CoV-1), SARS-CoV-2 enters host cells through human cell receptor ACE2 but appears to demonstrate higher binding affinity and SARS-CoV-2 has been shown to potentially have a higher reproduction number, indicating a higher level of transmissibility. Given these emerging data and what is known about the transmission of other coronaviruses, airborne transmission via droplets and possibly droplet nuclei are the likely main mode of person-to-person transmission.

Dental healthcare providers are urged to closely monitor advisory statements from governmental agencies and professional organizations regarding best practices.
