Do you mean when you lost 500 Chinese they left for China?
Seems like they’re fearing pC attacks if they start closing boarders. So goes the Doo Doo Bird.A peaceful little birds that got extinct from its enemies of stupid greedy humans.
You can make masks with material maybe look up you tubes. You can just cut one out double it but better with cotton in between if cotton balls haven’t been sold out. If you can get white or light material even better because you can throw them into soap bleach and warm water 15-20 minutes rinse in hot and rinse. Be careful with more comfortable stretch material because fabric stretches leaving porous openings. Viruses are tiny and can get through things.
If you can trust what the Chinese say, the number of deaths are low but two young healthy Chinese men who got out to social media one died the other disappeared from his family who said he was sick.
Generally when a new virus jumps species .. if that’s what it did and not lab created… it can be more dangerous. Maybe it didn’t jump but was created who knows.
