COVID-19~ World-wide estimates. Is r^3 a good estimate for Ro?

We investigate if r^3 (r cubed) is a good estimate for Ro for COVID-19. We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may infect when there…

COVID-19~ Worldwide estimates if Ro ~ exp(2.5r – 2.5)

We look at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may infect when there is no immunity in the community over a ten-day infectious period, and “exp” means “e to…

COVID-19~ Does Ro = exp(2.5r – 2.5)?

In this post we consider whether Ro = exp(2.5r – 2.5) is a good estimate for Ro where r is the daily increase in case numbers early in an outbreak. We consider this graph: We have already considered r^2.5 and r^(10/3) for various values of r. We add these to the graph: Below are the…

COVID-19~ refining our estimate for Ro

We have considered that Ro = 1.1r^2.5 provides a good estimate for Ro, where r is a daily increase in case numbers early in an outbreak, and Ro is the average number of people that one person may infect when there is no immunity over a ten-day infectious period. We now consider if Ro =…

COVID-19 in 2020~ 1.1r^2.5 compared with literature meta-analyses

In this post we update our earlier results and compare our results with meta-analysis in the literature. In 2020 we developed a formula for Ro, the number of people one person may infect over a ten-day period when there is no immunity, based on the daily increase, r, in the number of cases of COVID-19….
