Environmental Health and COVID-19 Resource Library

As a result of the ongoing COVID-19 pandemic, environmental health staff at local health departments have had to adapt existing programs and respond to new challenges. To support local health officials, NACCHO has gathered and developed resources to address the needs of environmental public health staff during the COVID-19 pandemic.
