Delta variant likely to become dominant in U.S

Delta variant

Dr. Scott GottliebTrusted Source, the former head of the Food and Drug Administration (FDA), told “Face the Nation” yesterday that the coronavirus variant known as delta is likely to become the dominant source for new infections in the United States and could lead to new outbreaks in the fall, with unvaccinated people being most at risk.

“Right now, in the United States, it’s about 10 percent of infections. It’s doubling every 2 weeks,” Gottlieb said. “That doesn’t mean that we’re going to see a sharp uptick in infections, but it does mean that this is going to take over. And I think the risk is really to the fall that this could spike a new epidemic.”

Gottlieb emphasized the delta variant is going to continue to spread, citing new data from prominent British epidemiologist Neil Ferguson, PhD.

“There was data out from Neil Ferguson this week showing it’s about 60 percent more transmissible than 1.1.7, which was that old U.K. variant that they’re now calling the alpha variant,” Gottlieb explained.

“So, this is more contagious. It appears that people who get this virus have higher viral loads and they have those viral loads for longer periods of time. So they shed more virus,” he said.
