Bayesian data assimilation for estimating instantaneous reproduction numbers during epidemics: Applications to COVID-19
Fig 4
Epidemic dynamics in Wuhan (A), Hong Kong (B), United Kingdom (C) and Sweden (D). The top row of each subplot shows the number of daily observations (in yellow), the estimated daily observations (in blue) and the estimated daily infections (in green). The middle row compares the DARt Rt estimation (in black) with the EpiEstim results (in blue) and EpiNow2 (in yellow). The distributions of all estimated Rt are with 95% CrI. The bottom row shows the probabilities of having abrupted changes (Mt = 1) (in green bars).
