Study Demographics for Influenza A Virus Household Transmission Analysis, 2017-2019

Demographic and specimen data from a household cohort study investigating influenza A virus evolution and transmission. The dataset includes information from 384 children and household contacts with RT-PCR-confirmed influenza A infections, representing A(H1N1)pdm09 and A(H3N2) viruses collected between 2017 and 2019. It was authored by Hunter J. Ries and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Modeling transmission bottlenecks based on the identification of 40 transmission events in 31 households.
• Analyzing selection pressures on viral hemagglutinin (HA) and neuraminidase (NA) proteins during acute infection.
• Studying host demographic factors in relation to weak purifying selection patterns across the viral genome.

Strengths

• Data is derived from a large cohort of 384 confirmed influenza A cases.
• Covers two major influenza A subtypes (A(H1N1)pdm09 and A(H3N2)) over a 3-year period (2017-2019).
• Explicitly identifies 40 transmission events for analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope or summary-level data.
