In the 20th century, biological warfare researchers learned how to make the plague much more deadly through genetic engineering.

The report said 189 people were being monitored following the illness of an employee at an anti-plague research institute in Irkutsk. Alexei Tsydenov, head of the nearby Republic of Buryatia, said the woman had died from an unspecified form of plague.

If it's just a plague, no. If it was weaponized, possibly. But that's unlikely.

We could, and would, quickly run out of antibiotics in the case of exponential spread.

No, not really.

I once got down voted to hell because I was accused of Russophobia. I am not. These plagues, no matter where they originate, are not natural, they are bioengineered on purpose to be resilient against modern medicine AND the use of antibiotics might even boost their lethality.

Bioweapons need to be made the most illegal of all weapons. More than nukes, too.

Pneumonic plague is much more dangerous than bubonic plague.
