Ottawa – Sepsis, a lethal disease, is a medical emergency that has been dubbed a “silent killer” by medical professionals and is fatal if left untreated. It is caused by the human body’s strong response to an infection and occurs as a result of the infection setting off a series of events that shut down body tissues and organs. Its symptoms that you must look out for include a very high or low fever, sweating, intense pain, clammy skin, dizziness, nausea, a rapid heartbeat, slurred speech, and confusion. Sepsis affects 1.7 million people across the US annually and kills 350,000 annually, while, in the UK, it causes 245,000 cases and 48,000 deaths annually.
