@Billius27 @harriettmb Grateful for comprehensive manifesto by #healthcare workers. I liked the part about “multi-layered protections. That’s a useful phrase. People take #ventilation and #vaccination for granted, ignoring #testing and #tracing. I was unfamiliar with the term #nosocomial, but not the concept. Members of my circle of friends, family working in healthcare note patients’ vulnerability to #airborne disease. Elder friends awaiting care in ERs contracted Covid-19.
