You’re making uninformed assumptions and obviously don’t work at a Covid center in the USA. Personnel are now careless, many are fatigued and/or disillusioned, protocolsuu are not universal or enforced, many buy into the political drama and don’t mask when outside the facility and patients have become argumentative about masking. The moment I have another career option is the moment I quit. PPE use / enforcement and availability is also spotty. People are tired of arguing with their coworkers about it, too.
