This repository contains code and data to compare the serial interval in the recent COVID-19 cases infected with the B.1.617.2 variant with COVID-19 identified before Apr 2020 (i.e. prior to the occurrence of the major global SARS-CoV-2 variants). The analysis is confined pairs of a primary case and a secondary case occurring among household members.
Data for the serial interval observed in household pairs of recent COVID-19 cases infected with the B.1.617.2 variant and cases identified before Apr 2020 are:
householdPair_b.1.617.2.csv
householdPair_preLD.csv
R scripts to perform the analysis and plots are:
serial_interval.R
serial_interval_plot.R
