The Los Angeles Times interviewed UCLA Fielding School of Public Health dean and professor of biostatistics Ron Brookmeyer about the increasing rate of test results coming back positive in Los Angeles County - 8.8% at the end of tast week, as compared to 5.8% two weeks ago.
Of the many coronavirus metrics rising in California, one of the most troubling is the rate in which coronavirus test results are now coming back positive.
A Times data analysis found that as of Friday, 5.7% of coronavirus test results in California over the preceding seven days came back positive, a rate not seen since early May. A week ago, the rate was 4.7%, a rate that had been largely stable for June until just Sunday, when there was a dramatic shift in the numbers.
Health officials say the rising percentage of coronavirus test results confirming infection indicated that the virus is beginning to spread in communities as more counties in California ease stay-at-home orders, allowing many businesses to reopen.
