Health experts expressed alarm Wednesday at news that the Centers for Disease Control and Prevention had changed its guidance on testing for COVID-19 and will no longer recommend a test for people who show no symptoms.
As asymptomatic carriers are a key reason for the spread of the virus, the news was widely criticized on social media and elsewhere.
“You do not necessarily need a test unless you are a vulnerable individual or your health-care provider or state or local public health officials recommend you take one,” the CDC said.
That marks a change from previous guidance that people who had spent more than 15 minutes with an individual who had tested positive for the virus should also get tested, regardless of the presentation of symptoms. The U.S. has conducted more than 73 million tests this year, and about 6 million of them have come back positive, according to the COVID Tracking Project.
