Just because politicians have "declared" the pandemic over, it is by far not over yet - we are still seeing significant excess mortality [1], and across Germany many companies are complaining about significant amounts of people on sick leave, most noticeably in public transit. Guess where that comes from... it's a lot of Covid.
SARS-CoV-2 is an incredibly dangerous virus and way too many people aren't even doing air purifiers any more because these are "too expensive to run" and whatnot.
