TRV-025

TRV-025 is known as the Vampire virus. Although unable to survive in human blood it gives all bats a desire to drink blood of humans. This makes bats more aggressive and even dangerous.

The bats originally tested became very aggressive almost instantly after being injected. The virus made them want to bite humans, however they showed no interest in biting each other, despite how thirsty they were.

After 5 weeks the bats managed to escape containment. The bats were eventually put down by a 'clean up crew'. The bats are known to have killed 232 scientists and 15 security personnel during this escape.
