The Evolution and Impact of Rabies

Rabies is a particularly insidious RNA virus primarily transmitted through animal bites. Once the virus enters the body, it targets nerve cells, gradually making its way to the brain, which leads to devastating neurological symptoms. The progression of the disease varies depending on the site of the bite, illustrating the relationship between the distance from the bite to the brain and the speed at which symptoms manifest. This slow progression has not hindered the virus's terrifying reputation, as it is virtually 100% fatal once clinical signs appear, causing fear historically among humans and shaping cultural narratives around rabies.
