Obviously this isn't as deadly as the Spanish flu. But look what ended the Spanish flu. It basically spread around until people either died off or got herd immunity. Vaccines didn't exist until the 40s.

There are only two legit ends to stop this virus:

1. Effective vaccine. This can take 12-18 mos. A long timeframe!

2. Let virus spread (which it already is), and let the people get it. Herd immunity. 98.5% of the population gets it and recovers just fine. Keep the other susceptible/compromised people at home quarantined away safely. This would end the pandemic much quicker. Downside is the hospitals could become overwhelmed, in fact the hospitals are already overwhelmed now.

The Spanish flu was 1918 to 1920 before it was over. Corona came Dec 2019. I really hope we aren't looking at Dec 2021 until this goes away. Let alone the airlines, we're all screwed in every industry (except healthcare).
