    Risk averse reproduction numbers improve resurgence detection. by Kris V Parag, Uri Obolski

    Published 2023-07-01
    “…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. Applying E-optimal experimental design theory, we develop a weighting algorithm to minimise these issues, yielding the risk averse reproduction number E. …”
