Survival analysis of SARS-CoV-2 variant epidemics: Influencing factors and duration of epidemics
Abstract Background : The COVID-19 pandemic has been marked by the emergence of numerous variants and mutations of the SARS-CoV-2 virus, each exhibiting distinct epidemiological characteristics. Understanding the factors influencing the duration of these variant-specific epidemics is crucial for effective public health planning and response. Survival analysis of SARS-CoV-II variants Objective : This study aims to analyze the impact of various SARS-CoV-2 variants and associated factors on epidemic duration using survival analysis techniques. We investigate the influence of mortality rates, basic reproduction numbers (R0), specific variants types, and epidemic waves on the duration of local outbreaks. Methods : We utilized a dataset containing information on SARS-CoV-2 variants, their dates of detection, and associated case and mortality data across different countries. We applied survival analysis using a Cox proportional hazards model with time-varying covariates to model the duration ...
