The common cold, allergies and the flu hit us without warning. We end up looking for relief and answers, but an Internet search about an illness can be frustrating, misleading and even scary. McNeil Consumer Healthcare — the division of Johnson & Johnson that manages over-the-counter medicines — wanted to help families demystify cold, flu and allergies by providing easy-to- follow solutions that offer quick and effective relief. To help them accomplish this, Mirum created the HealthDay mobile app, which uses patent-pending technology to compare and aggregate multiple data streams to show what bugs are going around, their common symptoms and how severe or widespread the illnesses have become.
