COVID-19 cases are increasing in the United States – and could get even worse over the coming months, federal health officials warned in urging areas hardest hit to consider reissuing calls for indoor masking. Increasing numbers of COVID-19 infections and hospitalizations are putting more of the country under guidelines issued by the U.S. Centers for Disease Control and Prevention that call for masking and other infection precautions. Right now, about a third of the U.S. population lives in areas that are considered at higher risk — mostly in the Northeast and Midwest. Officials said Wednesday those are areas where people should already be considering wearing masks indoors  — but Americans elsewhere should also take notice.

Ten of millions of people in the United States opted for mail ballots during the pandemic election of 2020. This year, voters in the early primary states are returning in droves to in-person voting. In Georgia, about 85,000 voters have requested mail ballots for the May 24 primary. That's a dramatic decrease from the nearly 1 million who cast mail ballots in the state’s 2020 primary at the height of the pandemic. Early in-person voting in the state is shattering records. The trend away from mailed ballots is seen in Ohio, Indiana and West Virginia, which also have held early primaries.
