Exhaust Popping on Deceleration. Deceleration backfire is caused by fuel burning in the exhaust manifold or header.

Rabies is mostly transmitted to humans, and between animals, through the saliva of infected animals. Transmission is generally through a bite from any infected animal. Transmission between humans is extremely rare, although it can happen through organ transplants, or through bites.
Contact transmission of a pathogen is possible by contact with almost any infected body fluid, e.g., blood, mucous, semen: Sweat and tears are not generally considered to be a high-risk body fluids and contact transmission of a pathogen from these fluids would be very unlikely.
