We find that more than 21% of the population would need to be tested every day to reduce the Covid-19 reproduction rate (R’) to 0.75, as opposed to 7% as argued by Romer. We show this using a corrected method for calculating the impact of an infectious person on others, when testing and isolation takes place. Our calculation allows for asymptomatic cases. Instead we propose ‘stratified periodic testing’ as an alternative strategy.” Link here.
