It’s a little surprising how much effort went into things early in the pandemic that didn’t pan out.
Official contact tracing in the US is a complete dud and had negligible impact on the spread. People informing their fiends/family “hey I just got Covid you should probably test/isolate” was what practically can make a difference.
Ventilators were the critical thing until we realized they were a very sub optimal treatment.
All the surface cleaning was a massive waste too... and the chemicals used in some places destroyed a bunch of furniture.
Masks, fresh air, don’t go out when sick or after close contact with someone when sick. Simpler things that make the most difference.
