What are common signs and symptoms of an ear infection?

Fever and reduced hearing are indeed common signs and symptoms of an ear infection, making this the correct choice. An ear infection can cause inflammation and fluid buildup in the middle ear, leading to discomfort and pain. The increase in body temperature, or fever, is a typical response to infection as the body works to fight off pathogens. Reduced hearing often results from the fluid interfering with the normal functioning of the ear, making it difficult for sound to travel through. These symptoms, combined, provide a clear indication of an ear infection, allowing for appropriate assessment and treatment.

In contrast, while a rash and swelling can occur in some infections, they are not typical of ear infections specifically. Coughing and sneezing are more aligned with respiratory infections and allergies rather than ear issues. Similarly, nausea and vomiting can occur with various medical conditions, but they are not hallmark symptoms of an ear infection. Understanding these key signs aids in proper diagnosis and treatment planning in clinical practice.
