Director of the US Centers for Disease Control and Prevention Dr Rochelle Walensky explained the agency’s stance on rapid tests on CNN’s New Day Wednesday. Walensky says CDC doesn’t recommend rapid tests to end Covid-19 isolation because they don’t know how they perform or predict how highly contagious people are in the late stages of infection.
Walensky said when asked why the CDC doesn’t recommend rapid testing during quarantine after you’ve been quarantined. “We chose not to do rapid tests for isolation because we really don’t know how our rapid tests work and they predict whether you are contagious in the late stages of the disease. Are not.”
The US Food and Drug Administration has not authorized them to use it, and does not know how they do it, she said.
“So what we’re saying is, if you have a quick test in five days and it’s negative, we don’t believe you’re still contagious,” she said. “We don’t want to leave a false sense of security, we still want you to wear a mask. And if the result is positive, we still know the maximum transmission behind you, we still want you to wear a mask and assume we won’t change our recommendations based on the results of the test. That quick check, we chose not to include it. ”
When asked why healthcare workers needed to test negative just a few days ago, according to CDC guidelines, but not the public, Walensky said that recommendations for infection control in care workplaces health is “always more rigorous” than the general population.
She also said that the decision had nothing to do with the shortage of rapid tests, saying that “the decision is really from an isolationist point of view related to the fact that we are not going to change our guidelines.” based on the results of that quick test. And you know it has nothing to do with any shortages at all, because we recommend doing a quick check of those in quarantine. ”
