TL;DR: In this article , the presence and fraction of reads supporting mutations specific to either the Delta or Omicron variants of SARS-CoV-2 was analyzed and the authors identified 18 co-infections, one of which displayed evidence of a low Delta-Omicron recombinant virus population.

A Snapshot of COVID-19 Incidence, Hospitalizations, and Mortality from Indirect Survey Data in China in January 2023
J. Ramirez,S. Diaz-Aranda,Juliet Aguilar,Oluwasegun Ojo,Rosa E. Lillo,Antonio Fernández Anta +5 more
TL;DR: In this paper , the authors estimate the incidence of COVID-19 in China using online indirect surveys (which preserve the privacy of the participants) collected from Australia, the UK and China in January 2023.
Feature Selection for an Explainability Analysis in Detection of COVID-19 Active Cases from Facebook User-Based Online Surveys
Jesús Rufino,J. Ramirez,Jose Aguilar,Carlos Baquero,Davide Frey,Rosa E. Lillo,Antonio Fernández Anta +6 more
TL;DR: In this paper , a tree-based binary classification model was proposed for detecting COVID-19-positive cases from self-reported information, which preserves the most relevant features without compromising the detection performance.
