WASHINGTON (AP) — The White House doctor said that President Donald Trump was no longer at risk of transmitting the coronavirus but did not say explicitly whether Trump had tested negative for it. The diagnosis came as the president prepared to resume campaign rallies and other activities. In a memo released Saturday night by the White House, Navy Cmdr. Dr. Sean Conley said Trump met the Centers for Disease Control and Prevention criteria for safely discontinuing isolation and that by “currently recognized standards” he was no longer considered a transmission risk. The memo did not declare Trump had tested negative for the virus. But sensitive lab tests — like the PCR test cited in the doctor’s statements — detect virus in swab samples taken from the nose and throat. Dr. William Morice, who oversees laboratories at the Mayo Clinic, said earlier this week that using the PCR tests, the president’s medical team could hypothetically measure and track the amount of virus in samples over time and watch the viral load go down.
