Massachusetts to halt elective surgeries due to COVID-19
On Friday, hospitals in Massachusetts will stop offering elective surgeries that can be safely postponed, Gov. Charlie Baker said at a press conference Monday afternoon.
"This action will free up unnecessary staffing and beds," Baker said. "We all know we're in the midst of a second surge. We're seeing a higher number of new cases each day. And in turn, an increase in hospitalizations statewide."
On Sunday, Massachusetts reported 4,747 new infections and a seven-day average testing positivity rate of 5.3%. There are 1,416 people currently hospitalized with COVID-19.
Despite the worsening statistics, the state is better prepared this time around, Baker insisted. In addition to reallocating hospitals resources, the state is ramping up and winterizing testing sites, stockpiling PPE and preparing two field hospitals in Worcester and Lowell.
