Oral healthcare workers are exposed to disease-causing organisms during dental procedures.
Pre-COVID-19 dentists wore some sort of respiratory protection like examination masks, surgical masks or respirators. COVID-19 has elevated the number of personal protective equipment needed.
There is immense interest in understanding whether potentially protective SARS-CoV-2 antibodies are provided to the baby via breast milk. This is what we know so far.
Modelling suggested Sydney would open up when NSW had around 1,900 new daily cases. Last Monday, it eased restrictions with just 496 new cases.
