• Droplet o Expelled infectious respiratory droplets which may lead to infection of others directly through susceptible mucosal surfaces (e.g., eyes, nose, mouth). • Airborne o Inhalation of small particles or evaporation of larger particles (in conditions of low humidity) that contain infectious agents o Aerosols containing infectious agents can be dispersed by air currents (e.g., ventilation or air conditioning systems) and inhaled o Exposure may occur from behaviours that generate aerosolised particles (e.g., coughing) or from performing an aerosol generating procedure (AGP). 22-25 • Combination o Combination of airborne, contact and droplet. Depending on the communicable disease, MRO or transmissible infection, it will require a combination of precautions to prevent their transmission.
