9. Plague (Yersinia Pestis)
Remember the Black Death in the 1400s? Nearly two hundred million people across Europe were presumably killed in a span of less than six years. It was one of the most devastating pandemics in history. And that is the result of this deadly weapon.
Knowing the danger this plague can cause, Japan used this bioweapon during World War II. The Japanese attacked China by dropping bags of rice and wheat with rat fleas carrying the plague over Chushien, China. More than one hundred people were eventually killed as a result of this action.
Yersinia Pestis, also known as Y. pestis, can be biologically generated to strike human body in three different ways. The first and probably the most unavoidable is its attack through your breathing (pneumonic). And the other two ways are through skin contact (bubonic) and bites (septicemic).
If those fleas bite you, the plague gets under your skin and infects your blood. If you manage to tap them off your body before they bite, the plague has got onto your skin and will infect you. And even if you can run or hide from them, they will leave the plague around and you may inhale it sooner or later. In other words, once you are attacked by this deadly weapon, you will die anyway.
