A child's cold may trigger rhinitis and bad breath. When a child catches a cold, it typically causes congestion and swelling of the nasal mucosa, leading to rhinitis. During rhinitis, the inferior turbinates on both sides often become enlarged and are frequently accompanied by infection, resulting in increased purulent nasal secretions. When these purulent secretions flow backward into the pharynx, they may cause bad breath.
