What makes influenza (the flu) spread between people

Modeling Core - Drivers of influenza A virus transmission in humans

NIH-funded research Emory University · NIH-11323035

This project uses computer models together with real flu data to learn how virus behavior and the immune response make people more or less likely to pass influenza to others.

What this research studies

From a patient perspective, researchers will use computer-based mathematical models fed with lab and clinical data to track virus levels and immune responses inside people who have the flu. The Modeling Core will work with other project teams that collect samples, symptom logs, and measurements of expelled virus and aerosols to fit and test these models. By linking within-person viral and immune dynamics to how much infectious virus a person releases, they aim to pinpoint the features that drive onward transmission. The findings are meant to reveal when someone is most infectious and which biological signs could guide better prevention or treatment timing.

Who could benefit from this research

Good fit: Ideal candidates are people with confirmed influenza infection (or participants in linked studies) who can provide samples, symptom information, and measurements related to virus shedding and aerosols.

Not a fit: People without influenza or those not enrolled in the linked clinical projects are unlikely to receive direct benefit from participating in the Modeling Core activities.

Why it matters

Potential benefit: If successful, this work could reveal when people are most likely to spread the flu and inform better timing of masks, isolation, and antiviral treatments to protect others.

How similar studies have performed: Related modeling studies combining clinical and lab data have improved understanding of viral dynamics for other infections, but directly linking within-person immunity to actual transmission is still an emerging research area.
