(CNN) – The three most-populous states in the US are reporting record increases in new coronavirus cases as concerning trends in the pandemic have emerged across the country.

California, Texas and Florida all set records for the number of new cases in one day. Nationally, 34,720 new cases were reported Tuesday in the US -- the third-highest number of new cases reported in one day since the beginning of the pandemic, based on a data archive kept by Johns Hopkins University. The two days with more cases were both in April.

Those three states account for 27.4% of the 328 million people living in the US, according to the latest US Census Bureau estimates.

Texas Gov. Greg Abbott urged people to stay home due to the surge, with some health officials calling for a stricter stay-at-home order.

"Because the spread is so rampant right now, there's never a reason for you to have to leave your home," Abbott told CNN affiliate KBTX. "Unless you do need to go out, the safest place for you is at your home."

New cases and hospitalizations are rising at their fastest rate yet, with Texas reporting 5,551 cases on Wednesday, breaking the previous record of 5,489 set the day before, health authorities said.

In the nation's most populous state, California obliterated its previous single-day high with 7,149 cases reported on Tuesday, according to state Department of Public Health. The previous record, set the day before, was just more than 5,000. Hospitalization and ICU rates due to the virus are also at an all-time high in the state.

Gov. Gavin Newsom pleaded with Californians to think of others by wearing masks, keeping a safe distance and increasing handwashing. Loosely quoting Scripture, Newsom implored residents to "love thy neighbors, like yourself, please."
