A few weeks of relief from isolation, huddling in your big coats outside chatting to a few friends in the evening after work, beginning to feel optimistic about the roadmap out of lockdown, and then another curveball comes in. This time in the form of the coronavirus variant called B1617 – which was first identified in India. Or rather, to be specific, B16172, because B16171 and B16273 have not shown such an alarming increase in cases.
The rapid increase in the proportion of SARS-CoV-2 sequences in England that are B16172 seem to indicate that its transmissibility exceeds even that of the B117 variant (the so-called Kent variant), which kept the UK in lockdown over the winter.
An initial feeling of unease, given the dreadful situation that has unfolded in India, has given way to genuine concern that this could be the problem that blocks the UK’s path out of lockdown. This would, of course, be a tremendous disappointment to a country that has been looking forward to a summer of freedom.
So perhaps us scientists shouldn’t say anything until we are more sure whether it could be a problem. But the consequences of not saying anything if it does turn out to be a valid concern could be catastrophic, and there may not be much time to act.
