Please note that the number of confirmed cases also depends on the underlying sampling process (i.e., infection tests). You may decide to incorporate the “tests per capita” in your models to get better predictions and statistics of estimates. For more information on unreported cases, see Li, Ruiyun, et al. "Substantial undocumented infection facilitates the rapid dissemination of novel coronavirus (COVID-19)." Science (2020).


Please also note that behavioral changes (e.g., no handshakes, social distancing, quarantine, etc.) influence the spreading parameters and outbreak dynamics.


Local interactions, social networks, and travel activities also have a large influence on the resulting spreading dynamics (see e.g.,

It might be important to account for spatial and surface-contact effects (see van Doremalen, Neeltje, et al. "Aerosol and surface stability of HCoV-19 (SARS-CoV-2) compared to SARS-CoV-1." medRxiv (2020)). Mean-field models and representative-agent models may lead to inaccuracies.
