Clinically, it is distinguished from self-limiting viral illness by symptoms persisting beyond ten days without improvement, severe presentation with high fever and purulent nasal discharge for consecutive days, or a "double-sickening" pattern where symptoms abruptly worsen after transient initial recovery

Clinically, it is distinguished from self-limiting viral illness by symptoms persisting beyond ten days without improvement, severe presentation with high fever and purulent nasal discharge for consecutive days, or a "double-sickening" pattern where symptoms abruptly worsen after transient initial recovery Frequent causative pathogens include *Streptococcus pneumoniae*, *Haemophilus influenzae*, and *Moraxella catarrhalis*
