Extreme Zoonosis is a tier 3 transmission. It crosses multiple species barriers, and increases infectivity in both rural and urban countries. It increases transmittive capabilities of the plague significantly, allowing animals to occasionally transmit diseases to islands with closed-off harbors and airports, such as Greenland. However, there may not be any guarantee that it may be able to transmit diseases if all animals are exterminated.
