Global Influenza Virus Sequences from 2000 to 2012

Aggregating 9,604 haemagglutinin sequences of human seasonal influenza viruses from 2000 to 2012, analyzed to compare global circulation patterns. It includes sequences for A/H3N2, A/H1N1 (up to 2009), B/Victoria, and B/Yamagatta virus types. The research was conducted by Trevor Bedford and published in 2020.

Use Cases

• Analyze the persistence of genetic variants across seasons for A/H1N1 and B viruses versus A/H3N2 viruses.
• Model the global dissemination patterns of new influenza variants, focusing on the role of East and Southeast Asia for different virus types.
• Investigate correlations between rates of antigenic evolution and the frequency of global movement for A/H1N1 and B viruses.
• Study differences in epidemic size and frequency in relation to the age of infection for various influenza virus types.

Strengths

• Contains 9,604 genetic sequences, providing a substantial basis for comparative analysis.
• Covers a 13-year time range (2000-2012) across multiple influenza virus types and subtypes.
• Data is associated with a published scientific study on global influenza circulation patterns.
• Released under a permissive CC0 1.0 public domain license.

Limitations

• The dataset is temporally limited, with the most recent data from 2012, potentially missing recent viral evolution.
• The raw data structure, including specific columns and file formats, is not described in the provided input.
• The geographic origin of the 9,604 sequences is not specified, which may limit spatial analysis.
