Coronavirus test results data in California may be defective



A sharp drop in the rate of California coronavirus infection announced this week by Gov. Gavin Newson may not be accurate, according to the state’s top public health official, who said Tuesday that the data system the status used to process the results of the COVID-19 tests is marked by technical problems. .

The exile has caused delays in the analysis of test results and has questioned Newsom’s announcement on Monday of a 21.2% drop in the seven-day average rate for positive infections compared to the average from the previous week.

California Secretary of Health and Human Services Dr. Mark Ghaly said “the seven-day positivity rate is absolutely affected”

; by the issue. It is not known to what extent and for how long the cases have been outsourced, and how this situation differs from the more routine delays when trial reports run out over the weekends.

The news comes as officials have expressed optimism that the rise in COVID-19 cases in California could live up to it.

An analysis by the Los Angeles Times found that California has now experimented its first weekly reduction in new confirmed cases of coronavirus for the first time in 12 weeks. For the seven-day period ending Sunday, California reported 59,697 new cases, a 9% drop from the previous week of 65,634 cases, which was a pandemic record.

Los Angeles County public health officials reported an additional 1,901 cases of coronavirus and 57 related deaths on Tuesday. In a statement, the health department said it learned of new technical issues related to the collection of test results during an emergency meeting Monday night with state officials.

“This issue underestimated the county’s positive cases and affects the number of COVID-19 cases reported each day and our contact-seeking efforts,” the county said.

The health department is working to contact at least 81 labs to get test results from July 26 to the present in order to determine the exact count.

The update follows county warnings last week that it expected a delay in cases “due to previous delays in reports from the state’s electronic lab system.” The next day, the county recorded highs of 4,825 new coronavirus cases and 91 deaths. Other counties, including Sacramento, Placer and Orange – which reported an additional 263 cases on Tuesday and two deaths – have recently included a warning in their scorecards that case reports may not be accurate.

“The state’s electronic disease information system has had problems processing incoming reports. Therefore, the recent data released on Sacramento County Public Health COVID-19 scorecards is likely to be an understatement of the county’s actual cases, ”the Sacramento Department of Public Health said.

Ghaly said the issue of subrest does not affect hospitalization and intensive care data. The numbers recently plummeted across California after the state saw two days of fatalities last week and topped 9,000 coronavirus-related deaths. Some counties continue to hit hard, while others see a decline in gravity. On Tuesday, San Bernardino County reported an additional 59 deaths, its highest number in a day so far.

Hospitalization data are collected differently from state test result numbers, which are collected using CALredie – an electronic system that feeds information from laboratories to state and local health systems.

California Department of Public Health officials are trying to determine “where the data is stagnating,” Ghaly said.

“We are not sure when we will have a definitive solution to the problem.”

Meanwhile, the health department is implementing manual processes to retrieve the information. Ghaly stressed the importance of focusing on long-term trends in snapshot data during a briefing on Tuesday afternoon.
