Prompted by a dramatic surge in cases across the nation and within their borders, three states on Monday reinstated restrictions that were put in place early in the coronavirus pandemic. At least 27 states have put a hold on reopening businesses or reimposed measures aimed at slowing the spread of the virus. Citing rising numbers, the governors of California and New Mexico -- having already taken some steps -- reimposed restrictions on dining. In Oregon, where the number of cases has recently risen, the governor expanded rules on face coverings to include outdoor gatherings where social distance cannot be maintained.
