Acute Bacterial Otitis Media
Acute bacterial otitis media is an infection of the middle ear, the air-filled space behind the eardrum, caused by bacteria. It is one of the most common reasons children visit a doctor, though adults are affected too. The hallmark symptoms are ear pain, a feeling of pressure or fullness in the ear, and fever. Young children who cannot describe pain may pull at their ears, become unusually irritable, or have difficulty sleeping.

What drives a middle ear infection
The bacteria most often responsible are Streptococcus pneumoniae and Haemophilus influenzae. They typically reach the middle ear via the Eustachian tube, which connects the ear to the back of the throat. A cold or upper respiratory infection can cause this tube to swell and trap fluid, creating conditions where bacteria thrive. In tropical climates across Southeast Asia, including Thailand, Malaysia, and the Philippines, high humidity and frequent upper respiratory infections mean ear infections remain common year-round rather than peaking only in winter.
Antibiotic treatment
Most cases are treated with a course of antibiotics. Oral cephalosporins such as cefdinir are a widely used option, effective against the bacteria most likely to be responsible. A full course is important even when symptoms improve quickly, to prevent recurrence or spread of infection.
Seek medical attention promptly if ear pain is severe, if hearing loss or discharge from the ear develops, or if symptoms do not begin to improve within 48 to 72 hours.
