Canaries in the Mine: An Update

by Rudolph Kalveks This was the snapshot of the parameters that describe the shape of the Coronavirus epidemic in terms of simple SIR models, based on the death statistics up to June 7th, shown in Table 1 of Canaries in the Mine: We can repeat the analysis making use of the additional death statistics over the two weeks up to June 21st. We observe that over this two week interval: There has been no substantial change in any of the parameters in Europe, USA, Australia.In particular, the parameter gamma for fatally susceptible sub-populations has only fluctuated by a couple of percent in these countries over the two weeks.Parameters for fatally susceptible sub-populations are looking better in South Africa, but worse in Brazil and India, and also worse globally. In conclusion, although the epidemics are obviously further progressed, over the last two weeks there has been no signal for any material change in the shape of the epidemic SIR model curves in Europe, the USA and Australia. Thus, the relaxation of lockdowns (well documented elsewhere) has so far had no discernible impact on the recovery from the epidemic in these countries. This undermines the analysis by Flaxman et al (published June 8th in Nature) that continues to predict a tenfold increase in the population at risk from the relaxation of lockdown ...
