I had a double whammy in January 2020, flu and/or cold twice in one month. rarely got sick enough that I physically couldn't work(back when I worked at crud restaurants that would still require you to work if you had the flu) and that january had me down twice (granted I also worked at a place where if you were sick they wouldn't let you work until you were better, and you needed a doctor's statement that you were safe to work to go back if you wanted to get back to work early.)
