A heavily criticized recommendation from the Centers for Disease Control and Prevention last month about who should be tested for the coronavirus was not written by C.D.C. scientists and was posted to the agency’s website despite their serious objections, according to several people familiar with the matter as well as internal documents obtained by The New York Times.
The guidance said it was not necessary to test people without symptoms of Covid-19 even if they had been exposed to the virus. It came at a time when public health experts were pushing for more testing rather than less, and administration officials told The Times that the document was a C.D.C. product and had been revised with input from the agency’s director, Dr. Robert Redfield.
