SACRAMENTO, Calif. (AP) — Gov. Gavin Newsom announced the largest spike in California's COVID-19 numbers in a single day Wednesday.

Newsom said Wednesday's total case number was 12,807 with a seven-day average of 9,420. The state's positivity rate is at 7.6%.

California’s confirmed coronavirus cases have topped 409,000, surpassing New York for most in the nation.

Johns Hopkins University data showed Wednesday that California now has about 1,200 more cases than New York. But New York’s 32,520 deaths are by far the highest total in the country and four times more than California’s tally.

And New York's rate of confirmed infections of about 2,100 per 100,000 people is twice that of California’s rate.

U.S. government data shows reported coronavirus cases underestimate the true number of infections.
