On the other hand, squirrels are infamous for spreading rabies. In reality, a squirrel getting infected with rabies is rather rare and the symptoms are consistently present, making it relatively easy to avoid. The symptoms of rabies in squirrels include excess saliva, sensitivity to light, and notably aggressive behaviour. Rabies will only spread to humans if the squirrel breaks your skin with a bite or a scratch, so if you keep your distance, it shouldn’t be an issue. If you hurry to the hospital after the transmission, rabies can be treated with ease but if you let the disease fester it can quickly become life-threatening.
