The sub-list contains simulators that are based on theoretical models. Due to the high number of pre-print research created and driving by the COVID-19 pandemic, [2] especially newer models should only be considered with further scientific rigor. [3] [4]
Such a phenomenon appears to have happened during the H1N1 bird flu pandemic of 2009, during which other strains of flu and RSV “disappeared” for a time, as Osterholm points out.
