The United States Centers for Disease Control and Prevention (CDC) amended its COVID-19 guidelines with regard to Corona testing. The current CDC guidelines no longer recommend the Corona test for those who show no symptoms even though the person was previously known to be in close contact with Corona patients.
Before being renewed, the CDC previously advised someone who contacts Corona patients to be tested to prevent potential transmission of Corona from asymptomatic or pre-symptomatic. “Testing is recommended for all close contacts of people with SARS-CoV-2 infection. Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that individual contacts with SARS-CoV-2 infection are quickly identified and tested,” the CDC previously advised.
New CDC guidelines
Now, the CDC emphasizes in its latest guidelines for people who meet at least a few minutes with a Corona patient not to be tested.
“If you have been in close contact within 2 meters of someone with COVID-19 for at least 15 minutes, but have no symptoms, you do not need the test unless you are a susceptible individual or your healthcare provider or state or public health official. local recommends you for a Corona test, “said the CDC, quoted from CNN International.
“Not everyone needs to be tested,” stresses the CDC.
“If you are having the test, you should self-quarantine or isolate at home while waiting for the test results and follow the advice of your health care provider or public health professional,” wrote the CDC on its official website.
In a pandemic planning scenario, the CDC says its best current estimates are that 40 percent of Corona infections are asymptomatic and 50 percent of transmission occurs before symptoms appear. The CDC did not explain the reasons for the changes and many doctors were confused about these changes.
Pros and cons of revised CDC guidelines
“I am concerned that these recommendations show that someone who has been substantially exposed to people with COVID-19 now does not need to be tested,” said Dr. Leana Wen, an emergency doctor and professor of public health at George Washington University.
“This is key to contact tracing, especially considering that up to 50 percent of all transmissions are caused by people who have no symptoms. People are wondering why these guidelines were changed – is it to justify continuing testing deficits?” he continued.
Meanwhile, a spokesperson at the US Department of Health and Human Services (HHS) denied the changes would affect contact tracing efforts, which most public health officials say is key to coronavirus control. “The updated guidance does not spoil contact tracing or other types of surveillance testing,” the spokesman said.
HHS said communities should consult their doctors or with local health officials to decide if they need to undergo tests. “The guidelines fully support surveillance public health testing, which is carried out proactively through federal, state and local public health officials,” said the spokesperson.
