ロックダウンはどうなのよ？と。

これは本当に何がいいたいか分からなくて、イギリスでもドイツでもフランスでもロックダウンすればまあまあ下がる。（あいつらはその後が悪い）ここまで広げちゃったんだから９月中ばまでできるだけ閉めないと問題解決しないよ。 https://t.co/fLO3HxJSsp

短期的には効果あるのでは。武漢の例だとロックダウン後4日以内は新規感染者が大幅減少し5日目以降は抑制効果なし https://t.co/xTOqN7wcwh
RT @giga_frog まず日本ではロックダウンできないし、他国でもロックダウンと新規感染の減少には関係がないことが明らかなのに。 https://t.co/kV7Ad2SRfW

Do lockdowns really work? Here’s what we know May 28, 2021

There are varying degrees of claims and estimates – but most tend to acknowledge the positive impact of lockdowns.

 

An Imperial College of London study estimated that lockdown saved millions of lives worldwide. Another study conducted by University of California, Berkley, analysed the impact of lockdown across six countries – China, South Korea, Iran, France, Italy and the United States. The study claimed that lockdowns averter as many as 62 million cases in these countries alone.

 

There are, however, others that put a more modest claim, saying there “may have been other policies that better mitigated the spread of COVID-19,” and that their study did not find “detectable effects of these policies on disease spread or deaths.”

What is WHO’s position on ‘lockdowns’ as a way of fighting COVID-19?

Large scale physical distancing measures and movement restrictions, often referred to as ‘lockdowns’, can slow COVID‑19 transmission by limiting contact between people.

However, these measures can have a profound negative impact on individuals, communities, and societies by bringing social and economic life to a near stop. Such measures disproportionately affect disadvantaged groups, including people in poverty, migrants, internally displaced people and refugees, who most often live in overcrowded and under resourced settings, and depend on daily labour for subsistence.

WHO recognizes that at certain points, some countries have had no choice but to issue stay-at-home orders and other measures, to buy time.

感染拡大抑制に効果はあるという説が多いようだが、ロックダウンは社会経済生活がストップしてしまうのでその影響も大きく、特に弱者にしわ寄せも大きい・・・・やってもやらなくてもそれが最善だったかは将来の評価にゆだねられるようなものかもしれない。
