What is typically observed in an acute ear infection?

In the context of an acute ear infection, the presence of pus draining from the ear is a critical indicator. Acute ear infections, particularly acute otitis media, often manifest with fluid accumulation and pus in the middle ear, which may eventually lead to perforation of the eardrum. This results in the expulsion of pus or fluid through the ear canal, making it an observable and significant symptom.

While other symptoms such as fever or cold-like symptoms can be associated with ear infections, the characteristic of pus drainage is a more definitive indication of an acute ear infection. Pus indicates the presence of infection and inflammation, which is central to diagnosing acute otitis media. Severe headaches can sometimes accompany ear infections but are not typically a primary feature, making pus drainage a more direct sign of the condition.
