sarscov2_us_2022: Simulated SARS-CoV-2 variant frequency data (US, 2022)

In lineagefreq: Lineage Frequency Dynamics from Genomic Surveillance Counts

Simulated SARS-CoV-2 variant frequency data (US, 2022)

Description

A simulated dataset of weekly SARS-CoV-2 variant sequence counts for the United States in 2022. Includes the BA.1 to BA.2 to BA.4/5 to BQ.1 transition dynamics. This is simulated data (not real GISAID data) to avoid license restrictions while preserving realistic statistical properties.

Usage

sarscov2_us_2022

Format

A data frame with 200 rows and 4 columns:

date

Collection date (Date, weekly).

variant

Variant name (character): BA.1, BA.2, BA.4/5, BQ.1, Other.

count

Number of sequences assigned to this variant in this week (integer).

total

Total sequences for this week (integer).

Source

Simulated based on parameters from published CDC MMWR genomic surveillance reports and 'Nextstrain' public data.

Examples

data(sarscov2_us_2022)
x <- lfq_data(sarscov2_us_2022, lineage = variant,
              date = date, count = count, total = total)
