Yes and they are not common viruses that people get exposed to everyday.
- collyw 5y agoAs I understand it around 1 in 4 colds are caused by coronaviruses. The Diamond Princess cruise ship only ever had 20% of the passengers that tested positive, implying a fair bit of previous immunity.
- AuryGlenz 5y agoCoronaviruses are common, and India is also in the region where this nasty one originated. For all we know, a worse one swept through the population 3000 years ago and inferred some genetic immunity. Or they have cross immunity from recent infections. It’s weird this never gets talked about, considering how all of the countries near China did quite well (relatively).
