CDC makes recommendations, shares information, and provides guidance to help slow down the spread of COVID-19 in the U.S. including guidance for schools and businesses. CDC regularly shares information and provides assistance to state, local, territorial, and tribal health authorities. These local authorities are responsible for making decisions including “stay at home” or “shelter in place.” What is included in these orders and how they are implemented are also decided by local authorities. These decisions may also depend on many factors such as how the virus is spreading in a certain community.
