2019-2020 was also a big H1N1 (Spanish/Swine Flu) year, as were 2017-2018 and 2018-2019. Entirely possible that's what you remember reading about or getting. If COVID hadn't happened Spanish Flu would've been a big headline anyways; as it is, a lot of the people who think they got COVID before March 2020 probably actually had H1N1. Before then the case numbers are orders of magnitude higher for flu, but COVID was more transmissible and almost 10x more lethal, and so post-lockdown it dominated.
