As more countries around the world begin to ease restrictions and open up economies, increased attention is being paid to minimising the airborne spread of SARS-CoV-2, the cause of COVID-19, while indoors.
The US Centers for Disease Control and Prevention have published guidelines 'COVID-19 Employer Information for Office Buildings'. This contains information for building employees, building managers and owners and building operations specialists on the steps they can take to protect workers and clients by creating safe spaces. These include: checking ventilations and air circulation, conducting a hazard assessment where workers are most likely to be exposed and have close contact, put in place engineering controls for separation, educating workers and changing the way they work.
A research letter published in Environmental International has further detailed ways to reduce viral transmission inside public buildings including hospitals and schools. This includes increased ventilation, avoiding recirculated air or air cleaning and disinfection and minimising the number of people inside together.
Combining personal protection measures such as hand hygiene, cleaning high-touch points and using PPE along with reducing possible airborne transmission will assist with keeping the pandemic under control.
