Shorten infections

What this outcome means

Infection duration is how long an illness lingers, from the first symptoms until you finally feel back to normal. On DoseRank it maps to a defined health outcome built from human studies on days to symptom resolution, total illness length, and time to recovery – data sourced from open sources and specialized resources. DoseRank is not medical advice.
