New coronavirus cases leaped in California in the week ending Sunday, rising 48% as 23,729 cases were reported. The previous week had 16,029 new cases of the virus that causes COVID-19.

California ranked 44th among the states where coronavirus was spreading the fastest on a per-person basis, a USA TODAY Network analysis of Johns Hopkins University data shows. In the latest week the United States added 490,277 reported cases of coronavirus, an increase of 10.3% from the week before. Across the country, 35 states had more cases in the latest week than they did in the week before.

Many states did not report cases on Easter. That will make some state-to-state comparisons inaccurate, and also some in-state week-to-week comparisons inaccurate.

Within California, the worst weekly outbreaks on a per-person basis were in Imperial, Merced and Del Norte counties. Adding the most new cases overall were Los Angeles County, with 4,903 cases; San Bernardino County, with 2,439 cases; and San Diego County, with 1,951. Weekly case counts rose in 29 counties from the previous week. The worst increases from the prior week's pace were in Los Angeles, San Bernardino and Orange counties.
