Speaker: Marika D鈥橝vanzo, PhD student at Federico II (Napoli University, Italy). She works on epidemiology, and her talk will be about early detection and dynamics of COVID-19 variants. More details below.
Abstract: In this presentation, we will explore a novel approach to analyse the evolution and spread of SARS-CoV-2 variants across different countries using genomic sequencing data. By employing an unsupervised clustering algorithm, we are able to identify chains of variants and fit their temporal dynamics using a sigmoid function. The study provides insights into key parameters, such as the time from the first case and the reaction time, which can serve as early indicators for new variant detection. Furthermore, we introduce a calibration curve to estimate t_0 based on the number of sequences available per week, offering a practical framework for future surveillance efforts. The results also highlight the ability to differentiate between stable and non-stable variant chains within a few weeks of detection, potentially providing a low-cost early warning system for emerging variants.
