Mucus Color During Flu: What It Really Tells You

Mucus color alone cannot determine how close you are to recovering from the flu. Mucus traps microbes and particles; its color varies with infection type, inflammation, or other conditions.

During viral infections like flu, mucus may turn yellowish or greenish due to white blood cells and enzymes fighting the infection—this doesn't necessarily indicate severity or duration.

To assess flu progression, consider other symptoms: fever, body aches, fatigue, respiratory signs. Consult a healthcare professional if symptoms persist or worsen.
