antvklik.com – The Centers for Disease Control and Prevention (CDC) have canceled its Covid-19 testing guidelines in its latest amendments. The changes were reportedly due to objections from the scientists themselves.

Earlier, on August 24, the CDC updated its testing guidelines, which said that those who are at low risk or do not show any symptoms do not need to be tested, after being exposed to infected people with coronavirus. But now, the CDC is back on its previous guidelines, that people who have had contact with coronavirus patients should be tested.

“Because many cases are driven by people who don’t show symptoms, people without symptoms who have been in close contact with people who are positive for Covid-19 need to be tested,” explained a clarification.

Reporting from Live Science, Saturday (19/9/2020), CDC said the latest changes were made as a form of clarification. This is because people can transmit the virus, without showing any symptoms before.

If a person has been in close contact with an infected person, for example within 1.8 meters for at least 15 minutes and has no symptoms, then testing is still necessary. This is the latest CDC guide.

Despite these changes, the science of asymptomatic or asymptomatic transmission has not changed, that people who are asymptomatic can transmit the virus. This is why the sudden change in CDC guidelines last month came under heavy criticism from public health experts.

It is not clear what percentage of Covid-19 cases do not show symptoms; a, but the CDC estimates that about 40% of people infected with Covid-19 never develop symptoms.
