SALT LAKE CITY (AP) — Utah logged its largest single-day increase in the number of COVID-19 cases Friday, with many of those coming in connection with an outbreak at a meatpacking plant in northern Utah. Health officials are investigating the “ongoing outbreak” at the unnamed facility and expect to see more cases. Many workers are considered part of vulnerable demographics. Meanwhile, Utah gubernatorial candidate Jon Huntsman Jr. is self-quarantining after a campaign staffer tested positive for COVID-19. The campaign said Friday that the former U.S. ambassador to Russia has postponed his in-person public events until he can be tested.
