Most influenza seasons peak in February, but there is significant variability (https://www.cdc.gov/flu/about/season/flu-season.htm).

I will resolve this market with the month that has the MMWR week ending when there is a peak overall weekly influenza hospitalizations rate according to https://gis.cdc.gov/GRASP/Fluview/FluHospRates.html

If the influenza season seems to be over before the end of the summer of 2023, I will resolve this market before closing time.
