OSHA List of workers at greatest risk of COVID-19 (Coronavirus). Healthcare workers are obviously at the top of the list of workers at risk. Other positions may not be as obvious, such as solid waste and wastewater management employees, who are included on the list. https://www.osha.gov/SLTC/covid-19/. Fortunately, most workers in the US have a very low risk of exposure to COVID-19 at their job. https://www.osha.gov/SLTC/covid-19/controlprevention.html. We encourage calm and lots of handwashing.
