Mortality rises among public when health workers get sick in an outbreak

When healthcare workers become ill during a disease outbreak, overall case counts and mortality rates may significantly increase, according to a new model created by researchers at Penn State. The findings may help to improve interventions that aim to mitigate the effects of outbreaks such as COVID-19.
