Aidsbies
When scientists combine the AIDS virus with the Rabies virus, a hybrid virus known as Aidsbies will be formed. When this virus is unleashed (most likely accidentally), the infected will develop a rapidly degenerative AIDS-like disease that also carries an irrational rage and hunger due to the rabies component of the virus. The rate of degeneration and the extent of the rage/hunger will be greatly amplified by the fact that this is a hybrid virus. This virus will be spreadable by contact with blood or bite, and will ultimately lead to the world's first real zombie outbreak. Be ready.
Oh shit! Those people running towards us got the Aidsbies! Run like hell!
