Are there any factors that lead to Sepsis. Of course, so that’s why many people are scared of getting infected. The disease is rather infectious as it is passed by the certain group of bacteria. The most popular cause is the fungal infection. In fact, it is possible to ‘catch’ Sepsis after being attacked by the systemic inflammatory response syndrome. The nasty bacteria may affect any part of the body, so it is impossible to predict. In most cases, the problem touches gastrointestinal tract, intravenous catheter, etc.
