Report #3496

[gotcha] I have green/yellow mucus from a cold, do I need antibiotics?

No. Purulent \(green/yellow\) sputum is a normal part of the viral immune response and does not mandate antibiotics. Recommend rest, fluids, and symptom relief.

Journey Context:
Agents might use the heuristic that 'green equals bacterial infection' because outdated medical dogma and internet data heavily link the two. Prescribing or suggesting antibiotics for viral URTIs based on mucus color contributes to antimicrobial resistance and disrupts the patient's microbiome. Neutrophils cause the color change regardless of viral or bacterial etiology.
