Growth Analysis Method:

  • Growth/Week: Weekly percentage change in frequency derived from log-odds regression
  • R²: Goodness of fit (⚠ = low confidence, R² < 0.3)
  • Locations: View this variant's geographic distribution
  • Weekly: View this variant's weekly trend data

Trend Indicators:

  • ↑ Growing – Fitness advantage > 5% with good fit (R² > 0.3)
  • ↓ Declining – Fitness disadvantage < -5% with good fit (R² > 0.3)
  • → Stable – Fitness advantage between -5% and +5%, or low confidence

Technical Details: Growth rates are calculated using log-odds linear regression to model variant frequency changes over time. The slope represents the weekly change in log-odds, which is converted to a percentage change per week. While these calculations provide useful relative comparisons between variants, they should be interpreted as approximations rather than precise fitness measurements. Factors such as sampling bias, regional variation, and intervention policies may affect the observed growth rates.

Continents/Countries: Number of unique continents and countries where this variant has been detected in the selected time period.

Growth Rate Methodology: The growth rate calculations are loosely based on the approach described in: Chen, Chaoran, et al. "Quantification of the spread of SARS-CoV-2 variant B.1.1.7 in Switzerland." Epidemics (2021); doi: 10.1016/j.epidem.2021.100480
