Shaking chills (rigors) are the body’s reaction to a severe infection or the release of organisms, such as viruses or bacteria, into the bloodstream. These chills often occur with a high fever and sometimes make teeth chatter or, when severe, can cause uncontrollable shaking that can make a bed vibrate.
