What makes influenza A spread between people

Clinical Core: Drivers of influenza A virus transmission in humans

NIH-funded research Emory University · NIH-11323038

Volunteers will be intentionally exposed to influenza A in controlled ways so researchers can learn which viral, immune, behavioral, or environmental factors make the flu spread between people.

What this research studies

If you join, you would come to Emory's Hope Clinic where healthy volunteers are intentionally exposed to a well-characterized influenza A virus by nasal drops, small-particle aerosol, or close interaction with an infected person. The team will closely monitor symptoms and collect blood, nasal swabs, and other samples, while recording behavior and environmental conditions during the contagious period. Those samples and data will be shared with other project teams and modelers to pinpoint drivers of transmission. The trial plans to enroll about 75 participants and builds on earlier safe CHIM work at Emory.

Who could benefit from this research

Good fit: Ideal candidates are healthy adults without high-risk medical conditions who are willing to be intentionally exposed to influenza and stay for close monitoring at the clinic.

Not a fit: People at high risk for severe influenza (including pregnant people, children, and those with certain chronic illnesses) should not join and are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this work could lead to better ways to prevent flu spread such as improved vaccines, targeted public-health measures, or clearer guidance on masking and distancing.

How similar studies have performed: Emory has already conducted CHIMs with this influenza strain, safely inoculating volunteers and achieving a high infection rate, and similar controlled infection studies have provided useful insights elsewhere.
