Summary

This study screens up to 5,000 healthy adults aged 18-65 to see if they can join future research on infectious diseases like flu and Zika. Volunteers undergo a 3-5 hour checkup including blood tests, heart exam, and chest X-ray. The goal is to build a pool of eligible participants for later studies, not to test any treatment directly.
