Ironic that nominally “locked down” NYC shows the quick spike with rapid falloff that you’d expect with a more open approach. Of course this isn’t surprising since NYC never closed their public transit — the ideal virus spreader — and thus were never really locked down. The result is they’ve more quickly approached herd immunity and are probably well positioned to avoid a “second wave”.
I told my NYC residing sister the same thing the other day. She was watching Fake News and they were scaring her about a second wave.
