The ZOE COVID Study is evolving to unravel the hidden links between immune health and future risk of diseases such as dementia, cancer, and heart disease. Using regular symptom reports to understand how often and how severely you get sick, and monitoring lifestyle behaviours to see how this changes over time, ZOE's Wider Health Studies are shaping up to be the next breakthrough in large-scale, community-led scientific health research - building on our work in gut health nutrition and COVID-19. We're taking the first step by launching a new 'study hub' in the app, where contributors can express interest and learn more about new studies into major diseases beyond COVID-19.
