Even at the first months the WHO said that lock-downs were last resort measures and that aggressive contact tracing and testing was the only practical solution before vaccines and effective treatments were found. It was also known early that at home transmissions formed the vast majority of transmissions and that Vitamin D and zinc deficiencies were determinant for complication and mortality rates. It is clear by now that stay-at-home orders are maintained or ended for political reasons.
