Is it true that they manufacture diseases now a days?

They are actually called biological agents depending on how they are used. They have been developing and producing diseases to study, defend and protect against the use of biological agents.





The earliest use of biological agents actually started when the Roman Empire used animal carcasses to contaminate their enemies' wells. Carthaginian leader Hannibal is credited with an interesting use of biological weapons in 184 BC. In anticipation of a naval battle with the Pergamenes, he ordered his troops to fill clay pots with snakes. During the battle, Hannibal sent the pots crashing down on the deck on the Pergamene ship. The confused Pergamenes lost the battle, having to fight both Hannibal's forces and a ship full of snakes. In 1346, Tartar forces led by Khan Janibeg attacked the city of Kaffa, catapulting the plague-infected bodies of their own men over the city's walls.





Of course, biological warfare tactics were introduced to America through the use of smallpox as a means to wipe out the Native American population when the pilgrims originally landed on the coast. They would give the Native Americans blankets that had been used be people already infected by the disease.
