Looking around the net it appears that common infections seen in nursing home facilities are MRSA, urinary tract infections, pneumonia, staph infections, influenza, strep
And of course if any residents of nursing homes have one or more of those infections, “covid” will finish them.
Sometimes VRE too. Vancomycin-resistant enterococci. Easily spread from person to person- and goes like wild fire through nursing homes, once a case starts-according to my Mom’s doctor.
VRE can cause many types of infections (for example, bloodstream infection , urinary infection, abscesses, wound infections, pneumonia, heart infections [endocarditis], or meningitis)
Hospitals will isolate the patient, and health care workers wear PPE and dispose of it before going to another room.
