What are common symptoms of bacterial infections?

Common symptoms of bacterial infections predominantly include gastrointestinal disturbances and systemic responses. Diarrhea, stomach cramps, and fever are particularly significant signs that may arise during a bacterial infection, as they indicate the body's reaction to the invading bacteria. The gastrointestinal tract is often affected because these pathogens frequently enter the body through contaminated food or water, leading to digestive issues.

Fever is also a classic response of the immune system attempting to combat the infection, signaling that the body is fighting against an invader. Alongside gastrointestinal symptoms, patients may experience varying degrees of discomfort, which makes diarrhea and stomach cramps critical signs of a bacterial infection. Understanding these symptoms helps food handlers recognize potential foodborne illnesses and take appropriate action to prevent the spread of contamination.

Other choices, while they may appear as symptoms of various health issues, are less directly associated with bacterial infections when compared to the specific gastrointestinal symptoms listed in the correct answer.
