The US could see an explosion of Covid-19 infections in the weeks following Thanksgiving, Dr. Jonathan Reiner, a former White House medical team adviser, told CNN Tuesday.

“It’s potentially the mother of all superspreader events.”

Many health officials believe the Midwest was seeded with Covid-19 last summer from just such an event, the Sturgis Motorcycle Rally in South Dakota, Reiner said.

“Now imagine that on a massive scale — people leaving from every airport in the United States, and carrying virus with them,” he added.
