Some thoughts on how fast cases are falling.
Firstly, it's brilliant that they are falling at all with the new variant.
Secondly, over the past week, taking 7 day average figures, cases have fallen about 20%, to about 50,000
At the point where restrictions were reduced to their least, last summer, cases were at just 400.
If cases continue to drop at the current rate, 20% per week, it will take roughly 21 weeks to reach 400. That's to mid June.
That takes no account of vaccination. If vaccinating just reduces cases, but has no effect on transmission, then the number of cases is reduced proportionately. Let's say half the population is vaccinated by May, that reduces the time to 400 cases by just 3 weeks to 18 weeks. End May.
If vaccinating reduces transmission significantly, then the *rate* of fall will accelerate. Let's say we average 30% fall per week rather than 20%, which is likely a best case scenario, roughly equivalent to vaccinating competely stopping transmission. That'll get us to 400 cases by 12 weeks, mid April.
Thought it might give some perspective on how well things are going.
Very preliminary figures, only a short period of lock down to judge effect, huge uncertainty on vaccination impact, but thought might give some perspective.
Stay home, try to stay strong, be kind.
