I think you can safely agree that they are not mutually exclusive and both of them are problems. In this particular case, it was a 100% fatality disease in a gain-of-function lab. It is being handled extremely seriously by Russia.

Perhaps the Russian military is overreacting with the blanket quarantines, but the odds are more likely that they understand the nature better than anyone else.

Again, normal pneumonic plague approaches 100% fatality rates. This is potentially a weaponized form.

This is an "oh, fuck" moment.
