Healthcare-associated infections rose in 2020, CDC says After years of decline, US hospitals saw significant increases in HAIs. CIDRAP

There was also a significant rise in methicillin-resistant Staphylococcus aureus (MRSA) bacteremia.

Prior to 2020, rates of HAIs in US hospitals had been declining since 2015, a decrease that has been attributed to improved infection prevention and control measures. But the surge of COVID-19 patients in 2020—and the diversion of hospital staff and resources to focus on care of those patients—clearly put a dent in those efforts. ...
