What makes the flu spread between people

Drivers of influenza A virus transmission in humans

NIH-funded research Emory University · NIH-11323033

Using carefully monitored flu infections in volunteers, researchers will track how influenza A grows, how the immune system responds, and how infectious aerosols are produced.

What this research studies

If you join, you would be intentionally infected with seasonal influenza A under close medical supervision in a controlled human infection setting so researchers can collect frequent samples. The team will take swabs and blood from different body sites and capture air samples to measure viral levels and infectious particles over time. They will compare how virus, immune responses, and aerosol production vary between people and between anatomical sites. Safety monitoring, treatment options, and close follow-up would be provided throughout participation.

Who could benefit from this research

Good fit: Ideal candidates are healthy adults eligible for controlled influenza challenge studies, typically without high-risk chronic conditions and able to stay at the study site for monitoring.

Not a fit: People at high risk for severe influenza—such as young children, pregnant people, older adults, or those with serious chronic illnesses—are unlikely to be eligible and would not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could lead to better ways to prevent flu spread, such as improved masks, ventilation guidelines, or timing of treatments to reduce infectiousness.

How similar studies have performed: Controlled human infection studies with influenza and other respiratory viruses have been done before and provided useful insights, though combining detailed aerosol measurements with high-resolution immune and viral dynamics is relatively novel.
