Do we need to monitor the exposure of health care staff to COVID-19?

For many hospital and health care workers the greatest worry right now is not inadvertently transmitting the COVID-19 virus to vulnerable patients. Home-health caregivers are being advised to take extra hygiene precautions and to stay home at the first signs of illness. Many nonessential care visits have been canceled. Assisted living communities and nursing homes are either banning or severely restricting visitors. Some employees of the home-care organization have access to a nursing team to guide their decisions. This is a time of resilience and confusion load for many of us on how to behave with the corona pandemic. Many contract workers are responsible for monitoring their own health and contagion risk levels.
Sounds like lots of individuals are taking individual decisions. Where is the role of the State here when they need to be protected at their turn, to protect, advise, support and save lives?
