“The (UK) variant probably accounts for about 1 per cent of cases in the US today, estimates Eric Topol at Scripps Research Translational Institute in California. But the picture is foggy, he says. “Surveillance is extremely poor.”
New daily cases in the US currently stand at 245,000 for the seven-day average, but Gigi Gronvall, also at Johns Hopkins University, says the UK variant isn’t the reason for the surge in transmission. “The variant is almost certainly not driving our current explosion of cases, or we would have more immediately found it in many states,” she says.
Even if B.1.1.7. isn’t yet driving an acceleration in US cases, there is reason to think it will in the future, says Warmbrod, given research in the UK has found it to be between 40 and 70 per cent more transmissible than earlier variants. When the variant is established in the US, says Topol, it will trigger “a major surge that makes the US holiday surges look minimal”.”
