Result sensitivity relative to the R₀-value as it would have been measured in Ho Chi Minh City. Light gray lines show the variation in a particular epidemiological indicator as a function of R₀. The other coloured lines are moving averages over nearby R₀-values. The top two panels show the size of the epidemic and the time taken for it to peak, which always have a predictable relationship to R₀. The bottom two panels show how animal exposure increases and how the epidemic becomes more rural as R₀ increases. Note that with higher R₀, not only does the risk to domestic animal owners increase but the relative risk of an owner to a non-owner also increases (not shown).
