I fear there is trouble on the horizon, even though things have been going really well.
The problem is the Indian variant: - B.1.617.2 In India it has been hard to come by reliable data.
However there I now problems with it in the UK. The UK has declared it a variant of serious concern. Boris Johnson has declared the situation serious. He says local lockdowns may be required. The trouble started in Blackburn and Derwent. Cases there are doubling fast. There is also serious trouble in Bedford, and as of writing cases are being detected in Northwest London. Serious illness, and deaths are already showing an early rise again, having been dropping spectacularly fast.
What we know.
The strain previously thought to be less infectious than the UK variant is in fact more infectious and causes more severe disease.
It seems able to cause more serious disease in the younger population and under 25s are at least half the cases. In Bedford and Boulton/Derwent the new stain is over half the cases and nearly 60% of cases on the that area. Here is a map of the affected areas, although it was drawn before the London cases.
The degree of vaccine resistance is not well known at this time. However there does appear to be a degree of vaccine resistance.
The response of the UK government has been surge testing with genome decoding in the affected areas. There is also surge vaccination for all over 18 in those areas. Plans for lockdowns are under consideration.
This is clearly a rapidly evolving serious situation that should concern us all. It seems to show why the problem in India is so catastrophic.
In the US this variant is spreading in the San Francisco Bay area. The CDC says it is not of concern. They had better start getting concerned really fast, before the US is caught on the backfoot yet again.
