Transmission of SARS-CoV-2: implications for infection prevention precautions
Airborne transmission of the virus can occur in health care settings where specific medical procedures, called aerosol generating procedures, generate very small droplets called aerosols. Some outbreak reports related to indoor crowded spaces have suggested the possibility of aerosol transmission, combined with droplet transmission, for example, during choir practice, in restaurants or in fitness classes.
Prevention summary:
Identify suspect cases as quickly as possible, test, and isolate all cases (infected people) in appropriate facilities;
Identify and quarantine all close contacts of infected people and test those who develop symptoms so that they can be isolated if they are infected and require care;
Use fabric masks in specific situations, for example, in public places where there is community transmission and where other prevention measures, such as physical distancing, are not possible;
Use of contact and droplet precautions by health workers caring for suspected and confirmed COVID-19 patients, and use of airborne precautions when aerosol generating procedures are performed;
Continuous use of a medical mask by health workers and caregivers working in all clinical areas, during all routine activities throughout the entire shift;
At all times, practice frequent hand hygiene, physical distancing from others when possible, and respiratory etiquette; avoid crowded places, close-contact settings and confined and enclosed spaces with poor ventilation; wear fabric masks when in closed, overcrowded spaces to protect others; and ensure good environmental ventilation in all closed settings and appropriate environmental cleaning and disinfection.

[Stop the Flu before it stops you]
Hello all Im following the recent developments re-the letter to the world health organisation flagging that COVID-19 may be transmitted by the airborne route. Is anyone else watching this and if so what do you think the implications will be for ICP if COVID-19 does turn out to be airborne as well as droplet and contact? What if anything are you doing to prepare for this possibility? I work in residential and community aged care so would particularly be interested in your feedback if you are also involved in these fields. Thanks very much in advance.
