I don’t think we’d stay locked down for so long. Even with the world on lockdown, the virus still spreads. Eventually I’d think we’d reach the 60–70% infected figure which is said to be enough for herd immunity. At that point and even without a vaccine it’s probably be safe to lift most or all restrictions while we’re looking for a vaccine. As I understand it the lockdowns are to avoid an unmanageable peak in hospital use, not to avoid most people getting the virus.
I wonder if China will strictly prohibit the hunting and eating of wild animals as a result from this outbreak and the considerable international pressure, or if it’ll keep going.
