Which of the following are common signs and symptoms of an infection?

1. Headaches and fatigue

2. Fever, chills, and wounds with a foul odor

3. Nausea and vomiting

4. Coughing and sneezing

The correct answer is: Fever, chills, and wounds with a foul odor

Fever, chills, and wounds with a foul odor are indeed common signs and symptoms of an infection. The presence of a fever is often a body's response to infection, indicating that the immune system is working to fight off pathogens. Chills frequently accompany fever as the body tries to generate heat to battle the infection. Additionally, wounds that emit a foul odor may be indicative of a bacterial infection, particularly if there is necrotic tissue or pus present. This smell comes from the bacteria breaking down tissue and producing waste products, which often signify the need for medical intervention. While the other options do present symptoms that can occur with various health issues, they are not as specific or indicative of an infection. For instance, headaches and fatigue can stem from many conditions, including stress or dehydration, while nausea and vomiting may suggest gastrointestinal issues rather than an infection. Coughing and sneezing are typically associated with respiratory infections, but they can also occur due to allergies or irritants. In this context, the combination of fever, chills, and foul-smelling wounds is the most direct indicator of an infection.
