Medical experts question new CDC coronavirus guidelines

On Wednesday, Redfield seemed to do an about-turn, agreeing with the new recommendations.

With all that in mind, it is more than curious that the Centers for Disease Control and Prevention this week quietly shifted its recommendation on testing.

Maria Van Kerkhove, a World Health Organization epidemiologist, said the United Nations agency recommended suspected cases and their contacts be tested, if possible, but the focus should be on people displaying signs of infection. Experts have consistently called for wide-scale testing, even of people without symptoms, since they can likely spread the virus to others while never feeling sick or shortly before symptoms appear.

Girior said the new guidance was not prompted by testing shortages. Dr. Anthony Fauci, a member of the White House Coronavirus Task Force, was undergoing surgery and was not apart of the August 20 task force discussion.

"I am concerned about the interpretation of these recommendations and anxious it will give people the incorrect assumption that asymptomatic spread is not of great concern. In fact it is".

But overwhelming evidence continues to suggest that asymptomatic cases are a key part of coronavirus transmission in the US. "There is ample evidence that asymptomatic and presymptomatic spread can happen". The CDC should be pushing to do more testing - much, much more - because the information the test results provide about where and how the virus is spreading is crucial to safely reopening hard-hit industries, resuming church services and letting students go back to classrooms.

CNN and The New York Times reported on Wednesday that USA public health officials were ordered by high-level members of the Trump administration to push forward with the changes. "Places that have had better control of the virus target more testing not less". "And I mean the medical and scientific experts, including CDC Director Redfield".

"Everyone who needs a Covid-19 test, can get a test", the CDC director said.

He added: "No new science, data, or research have been offered to justify such a change".

He asserted that the development rush won't pose "a risk to public health, because no vaccine is going to be released or used until the FDA has certified that it is both safe and effective".

On average just under 11,000 tests a day are performed in the state. Testing is a way out of the pandemic, and the way back to opening the economy and schools, she said. "It is important to get tested if you've been exposed to someone, even if asymptomatic, for contact tracing".

Meanwhile, federal health officials anonymously told CNN and the New York Times that the order about changing the guidelines did not come from the CDC, but from higher-ups as fewer tests would lead to fewer cases, creating a sense of a more controlled health situation. But President Donald Trump has referred to testing as "a double-edged sword" that reflects poorly on the US. "This is not something we had heard about, so I don't know the backstory on why CDC made that decision". The agency said 40% of total infected people don't show symptoms, while the infectiousness of these individuals relative to symptomatic people stands at 75%. "When we have the resources to test, we should be testing those with known exposure to help identify and recommend proper quarantine". And the truth of the matter is, if you want to make sure that the right people get tested with the right tests at the right time, then you need a national testing strategy that's been very thoughtful, that's science-based, that is in print and that everybody understands.
