US labs buckle amid testing surge; world virus cases top 15M
Associated PressWASHINGTON — Laboratories across the U.S. are buckling under a surge of coronavirus tests, creating long processing delays that experts say are undercutting the pandemic response. “The question is how many tests are being done with results coming back within a day, where the individual tested is promptly isolated and their contacts are promptly warned.” Frieden and other public health experts have called on states to publicly report testing turnaround times, calling it an essential metric to measure progress against the virus. “If that person is not quarantined in that 7-10 days, are they spreading without realizing it?” Test results that come back after two or three days are nearly worthless, many health experts say, because by then the window for tracing the person’s contacts to prevent additional infections has essentially closed. Dr. Leana Wen, a public health professor at George Washington University said it’s reasonable to tell people awaiting test results to isolate for 24 hours, but the delays have been unacceptable. Health experts assembled by the Rockefeller Foundation said last week that the U.S. should scale up to testing 30 million Americans per week by the fall, when school reopenings and flu season are expected to further exacerbate the virus’s spread.
