Theeffective reproduction number Ris a prominent statistic for inferring the transmissibility of infectious diseases and effectiveness of interventions.Rpurportedly provides an easy-to-interpret threshold for deducing whether an epidemic will grow (R>1) or decline (R<1). We posit that this interpretation can be misleading and statistically overconfident when applied to infections accumulated from groups featuring heterogeneous dynamics. These groups may be delineated by geography, infectiousness or sociodemographic factors. In these settings,Rimplicitly weights the dynamics of the groups by their number of circulating infections. We find that this weighting can cause delayed detection of outbreak resurgence and premature signalling of epidemic control because it underrepresents the risks from highly transmissible groups. ApplyingE-optimalexperimental design theory, we develop a weighting algorithm to minimise these issues, yielding therisk averse reproduction number E. Using simulations, analytic approaches and real-world COVID-19 data stratified at the city and district level, we show thatEmeaningfully summarises transmission dynamics across groups, balancing bias from the averaging underlyingRwith variance from directly using local group estimates. AnE>1generates timely resurgence signals (upweighting risky groups), while anE<1ensures local outbreaks are under control. We proposeEas an alternative toRfor informing policy and assessing transmissibility at large scales (e.g., state-wide or nationally), whereRis commonly computed but well-mixed or homogeneity assumptions break down.
