A very common reason is another prior illness that was caused by pathogens. These conditions may for instance be inflammation of the lungs or abdominal organs.

The whole body becoming inflamed means you are very ill. For example, you may have a high fever. Your heart may beat very fast and you may also breathe very quickly.
