Other than the incubation period, this sounds similar to Hanta virus.

My bet is a Morbillivirus, similar to the one that surfaced in Australia. That one was called the Hendra virus and found to be harboured by the fruit bat. Some of these viruses are harboured by the most unusual animals that to them are not pathogenic but to another species is devastating.
