Virus

Create your own virus that will kill all of humanity.
Name this data:
• Name
• Year of origin
• Place of origin (at least country)
• Virus specialization (zombie virus, plague, HIV or your own)
• Difficulty (on “minimum” something like the Middle Ages in medicine and hygiene, on “average” something like in real life, and on “How???” you will be monitored almost from the very beginning)
You can clarify something else if you want.
