[Ed. – It seems, according to the CDC, that they never changed their assessment; they just kind of misstated it in the “update” and decided the corrected update to the unchanged assessment wasn’t salvageable. Hey, it happens. Bottom line: heavy droplets.]
The top U.S. public health agency stirred confusion by posting — and then taking down — an apparent change in its position on how easily the coronavirus can spread from person to person through the air.
But officials at the Centers for Disease Control and Prevention say their position has not really changed and that the post last week on the agency’s website was an error that has been taken down.
It was “an honest mistake” that happened when a draft update was posted before going through a full editing and approval process, said Dr. Jay Butler, the CDC’s deputy director for infectious diseases.
The post suggested that the agency believes the virus can hang in the air and spread over an extended distance. But the agency continues to believe larger and heavier droplets that come from coughing or sneezing are the primary means of transmission, Butler said.
