The U.S. just saw a record 45,557 new coronavirus cases in a single day


The U.S. saw a record number of new coronavirus cases in a single day, with 45,557 diagnoses reported Wednesday, according to a tally by NBC News. Wednesday’s cases top the previous highest daily count from April 26 — during the first peak of the pandemic in the U.S. — by more than 9,000 cases, according to NBC News’ tracking data.

Arizona, Florida, California and Nevada reported record spikes in confirmed Covid-19 cases on Friday as states continue their phased reopenings and ramp up testing.

The Arizona Department of Health Services reported 3,246 new positive cases, exceeding Thursday’s single-day high of 2,519 cases. Florida health officials added 3,822 new cases Friday morning, surpassing the state’s previous single-day high of 3,207 cases also reported on Thursday.

California officials reported 4,317 new cases Friday that were confirmed on Thursday, topping the previous record of 4,084 reported on Thursday. The Nevada Department of Health and Human Services reported 410 new cases Friday afternoon, breaking its previous single-day high of 379 from Monday.

More states are reporting record-setting daily numbers of Covid-19 cases as infections spread at a rapid pace. The Centers for Disease Control and Prevention expanded its list of states where Covid-19 deaths are expected to accelerate over the next four weeks compared with the past four weeks. The list now includes Alaska, Arizona, Arkansas, Hawaii, North Carolina, Oregon, South Carolina and Utah.

While some state and federal leaders have attributed the rise in the number of confirmed coronavirus cases to increase in testing, many are seeing a climb in hospitalizations. This metric, like new cases and deaths, is also considered an important measure of an outbreak because it helps health officials gauge how severe it may be.
