Definition for Acute otitis
From Biology Forums Dictionary
Acute otitis media (AOM) is most often purely viral and self-limited, as it usually accompanies viral URI (upper respiratory infection). There is congestion of the ears and perhaps mild discomfort and popping, but the symptoms resolve with the underlying URI. If the middle ear, which is normally sterile, becomes contaminated with bacteria, pus and pressure in the middle ear can result, and this is called acute bacterial otitis media. Viral acute otitis media can lead to bacterial otitis media in a very short time, especially in children, but it usually does not. The individual with bacterial acute otitis media has the classic "earache", pain that is more severe and continuous and is often accompanied by fever of 102 °F (39 °C) or more.
