  14. Ok. Dr. Huffington. Claim that high PCR test sensitivity inflates COVID-19 cases wrongly conflates the issue of contagiousness with the presence of infection CLAIM “Dr. Anthony Fauci appeared to acknowledge that large numbers of positive COVID-19 cases may arise from oversensitive tests that pick up mere fragments of the virus rather than active, viable infections. If true, many patients may have been receiving false-positive test results” VERDICT  DETAILS Incorrect: Regardless of whether a person tested positive with a high or low viral load, a positive test indicates that the person is or has been infected with the virus, which qualifies them as a COVID-19 case. The high number of COVID-19 cases reported in the U.S. is due to a large number of infected people, not the PCR test's sensitivity. PCR tests to detect viral diseases that have a high level of sensitivity can produce a positive result even if a person only harbors trace amounts of virus or non-infectious virus, like in recovering patients. Hence a positive test result from a PCR test without additional information about viral load cannot be used to determine whether an infected person should self-isolate or their contacts should be traced. Although a positive test alone does not provide information about whether the person is contagious, it can confirm whether the person is infected and is useful for monitoring the spread of the virus. It is therefore appropriate to count a person with a positive result as a COVID-19 case.
