(CNN) The US Centers for Disease Control and Prevention shot down reports from the White House coronavirus task force that warned states of a more transmissible, homegrown "US variant" of coronavirus -- a misperception that began on a call with governors, an administration official told CNN. But the official made it very clear US health officials have not determined that a US variant of the virus exists. There has been discussion about whether US health officials should investigate whether a US variant exists and make that identification. Warnings about the variant made it into written reports dated January 3 that were sent to states and obtained by CNN. The reports warned of the possibility of a "USA variant" of Covid-19.
