Sepsis is a serious condition that arises when the body’s response to an infection leads to widespread inflammation. It often begins with a localized infection caused by bacteria or other pathogens, which can originate from various sources like pneumonia, urinary tract infections, or even a wound. If the infection is not controlled, bacteria can enter the bloodstream, thereby allowing the infection to spread throughout the body, leading to systemic symptoms.

In contrast, while pneumonia and strep throat are bacterial infections that can potentially lead to sepsis if untreated, they are typically localized infections that do not inherently spread throughout the body like sepsis. Influenza, on the other hand, is primarily a viral infection and does not fit the definition of a bacterial infection. Therefore, sepsis is the most representative option for a bacterial infection that can become systemic, as it directly involves a systemic response to a bacterial infection.
