These steps include screening everyone who enters the clinic for signs of illness, banning most visitors in the clinic, minimizing our own staffing and allowing some employees to work from home, and frequent sanitation of the clinic. We are using personal protective equipment such as masks, gowns, gloves, and face-shields according to national guidelines.
