Yes, and here is the recipe. Take a few hundred rats and infect them with rabies. 2 weeks later infect them with a bacterial infection. Bubonic plague would do nicely. Add a touch of influenza, not h1n1 but a milder version so you don't kill the host. Eventually a bacteria will become infected with both the rabies and the influenza viruses. These viruses will then combine and either die off or give you the fast acting, highly contagious version of rabies you are looking for. Much like cake needs frosting, you probably want the false death effect as well. Just get some blowfish dna and remove the gene for producing the neurotoxic venom and add it to your favorite non lethal virus. I would use the influenza virus again, due to it's easy access, and the speed at which it reproduces, and causes rapidly forming symptoms. Take 100 petri dishes and add growth medium to taste.mix 1 part neurotoxic virus and 2 parts rabies/flu virus and mix thoroughly. 2 weeks later infect your favorite patient zero and wait for the fun to begin. Tune in next time when we'll be making cyanide producing bacteria! Fun for the whole family!
