Challenges of COVID-19 Case Forecasting in the US, 2020-2021
Joseph Chadi Benoit Lemaitre, Pan Xu, Weitong Zhang, Wei Cao, Myungjin Kim, Shan Yu, Xinyi Li, Lei Gao
During the COVID-19 pandemic, forecasting COVID-19 trends to support planning and response was a priority for scientists and decision makers alike. In the United States, COVID-19 forecasting was coordinated by a large group of universities, companies, and ...
Public Library Science2024Spatially explicit effective reproduction numbers from incidence and mobility data
Andrea Rinaldo, Cristiano Trevisin, Enrico Bertuzzo, Lorenzo Mari, Damiano Pasetto, Marino Gatto
Current methods for near real-time estimation of effective reproduction numbers from surveillance data overlook mobility fluxes of infectors and susceptible individuals within a spatially connected network (the metapopulation). Exchanges of infections amon ...
2023Back-to-Africa introductions of Mycobacterium tuberculosis as the main cause of tuberculosis in Dar es Salaam, Tanzania
In settings with high tuberculosis (TB) endemicity, distinct genotypes of the Mycobacterium tuberculosis complex (MTBC) often differ in prevalence. However, the factors leading to these differences remain poorly understood. Here we studied the MTBC populat ...
PUBLIC LIBRARY SCIENCE2023Optimizing the mitigation of epidemic spreading through targeted adoption of contact tracing apps
The ongoing COVID-19 pandemic is the first epidemic in human history in which digital contact tracing has been deployed at a global scale. Tracking and quarantining all the contacts of individuals who test positive for a virus can help slow down an epidemi ...
AMER PHYSICAL SOC2022Epidemicity of cholera spread and the fate of infection control measures
Andrea Rinaldo, Cristiano Trevisin, Lorenzo Mari, Damiano Pasetto, Joseph Chadi Benoit Lemaitre, Marino Gatto
The fate of ongoing infectious disease outbreaks is predicted through reproduction numbers, defining the long-term establishment of the infection, and epidemicity indices, tackling the reactivity of the infectious pool to new contagions. Prognostic metrics ...
2022The Role of Adaptivity in Source Identification with Time Queries
Understanding epidemic propagation in large networks is an important but challenging task, especially since we usually lack information, and the information that we have is often counter-intuitive. An illustrative example is the dependence of the final siz ...
EPFL2022Switchover phenomenon induced by epidemic seeding on geometric networks
It is a fundamental question in disease modeling how the initial seeding of an epidemic, spreading over a network, determines its final outcome. One important goal has been to find the seed configuration, which infects the most individuals. Although the id ...
2021Effect of specific non-pharmaceutical intervention policies on SARS-CoV-2 transmission in the counties of the United States
Non-pharmaceutical interventions (NPIs) remain the only widely available tool for controlling the ongoing SARS-CoV-2 pandemic. We estimated weekly values of the effective basic reproductive number (R-eff) using a mechanistic metapopulation model and associ ...
NATURE RESEARCH2021A mathematical dashboard for the analysis of Italian COVID-19 epidemic data
Alfio Quarteroni, Luca Dede', Nicola Parolini
An analysis of the COVID-19 epidemic is proposed on the basis of the epiMOX dashboard (publicly accessible at ) that deals with data of the epidemic trends and outbreaks in Italy from late February 2020. Our analysis provides an immediate appreciation of t ...
WILEY2021Wastewater-based estimation of the effective reproductive number of SARS-CoV-2
Tamar Kohn, Krista Rule Wigginton, Xavier Fernandez Cassi, Timothy R. Julian
Background The effective reproductive number, Re, is a critical indicator to monitor disease dynamics, inform regional and national policies, and estimate the effectiveness of interventions. It describes the average number of new infections caused by a sin ...
