It is worth noting that the mortality rate is much higher than we were originally told, it is over 8% in Italy, and closer to 10% in China (although it is very hard to even estimate in China, as so many people died at home) Most were over 65, but not all.
None of us can be sure how our body will react to a new virus, young or otherwise. We can stop this by staying at home, keeping our children at home and not breaking this commitment however hard it may be (and it will be hard, we are on day 10)
Threads like this are frightening, but they serve a purpose. Stay at home, keep your children safe.
