Acute otitis media symptoms in 2 weeks: If symptoms persist beyond two weeks, which is most likely?

• A. The same organism
• B. A different organism
• C. A viral cause
• D. A fungal infection

Answer: (B)

When acute otitis media lasts two weeks or longer, it points to a new infectious cause rather than ongoing infection by the initial pathogen. In AOM the usual bacteria (such as Streptococcus pneumoniae, non-typeable Haemophilus influenzae, and Moraxella catarrhalis) typically respond to treatment within a few days. If symptoms persist to two weeks, the ear infection is more likely due to a different organism that wasn't covered by the initial therapy or possibly a resistant strain, rather than a mere continuation of the same one. Viral causes tend to resolve earlier, and fungal infection is uncommon in typical AOM unless there are special circumstances like chronic disease or prior antibiotic use. So persistent symptoms beyond two weeks fit the idea of a different organism causing the infection.
