In addition, a public hotline has been established for Iowans with questions about COVID-19. The line is available 24-7 by calling 2-1-1 or 1-800-244-7431.

Iowans who have traveled recently for business or spring break vacations, whether internationally or domestically outside of Iowa, should strongly consider self-isolating for 14 days. This will support the state's ongoing efforts to mitigate the spread of COVID-19, and limit the introduction of the virus from other points of travel, IDPH officials said.

Gov. Kim Reynolds will hold a Wednesday press conference at 2:30 PM. To view the live stream, CLICK HERE.
