Campus public health measures help mitigate the spread of COVID-19 Alongside regular saliva-based COVID-19 testing, other tools such as contact tracing, quarantine and isolation facilities, and health and well-being monitoring platforms are critical for protecting and supporting the campus community. Working in concert with the Penn Cares testing program, Penn’s public health strategy also includes contact tracing, the use of quarantine and isolation facilities, and health and well-being monitoring platforms. With the launch of the Penn Cares program late last year, weekly saliva-based testing for COVID-19 has become a key component of Penn’s spring semester campus reopening. Since the start of 2021, more than 109,000 tests have been conducted.
