Bluetongue is spread by small gadflies. They transmit the disease to sheep, goats and cows. Sick animals develop infections in the mouth, among other things. In animals that are very sick, the tongue turns blue. They also have a high fever, drool, walk lame and have a rounded back. The disease is not transmissible to humans. Unlike bird flu, animals that become ill do not need to be culled.
