From the Overview: "For the remaining 2020 elections, both primaries and in November, jurisdictions will still offer in-person voting, whether at Election Day polling places, or during early in-person voting at sites or the election offices. In the COVID-19 [coronavirus disease 2019] environment, election officials should understand potential election management considerations associated with health and safety at voting locations. Regardless of the size of a jurisdiction's in-person operation, methods should be developed to protect the health and safety of poll workers and voters. Decisions affecting upcoming elections should be made as soon as possible to facilitate a safe election and minimize the operational risks associated with changing processes and procedures at a late date. [...] The guidance in this document includes engineering and administrative suggestions that can help minimize or mitigate poll worker exposure to COVID-19."
