Abstract Academic researchers, government agencies, industry groups, and individuals have produced forecasts at an unprecedented scale during the COVID-19 pandemic. To leverage these forecasts, United States Centers for Disease Control Prevention (CDC) partnered with academic research lab University of Massachusetts Amherst to create US Forecast Hub. Launched in April 2020, Hub is a dataset point probabilistic incident cases, hospitalizations, deaths, cumulative deaths due county, state, national, levels States.

Abstract Many studies have used mobile device location data to model SARS-CoV-2 dynamics, yet relationships between mobility behavior and endemic respiratory pathogens are less understood. We studied the effects of population on transmission 17 viruses in Seattle over a 4-year period, 2018-2022. Before 2020, visits schools daycares, within-city mixing, visitor inflow preceded or coincided with seasonal outbreaks viruses. Pathogen circulation dropped substantially after initiation COVID-19 stay-at-home orders March 2020. During this was positive, leading indicator all lagging negatively correlated activity.

Significance Validated forecasting methodology should be a vital element in the public health response to any fast-moving epidemic or pandemic. A widely used model for predicting future spread of temporal process is an autoregressive (AR) model. While basic, such AR (properly trained) already competitive with top models operational use COVID-19 forecasting. In this paper, we exhibit five auxiliary indicators—based on deidentified medical insurance claims, self-reported symptoms via online surveys, and COVID-related Google searches—that further improve predictive accuracy The most substantial gains appear quiescent times; but search indicator appears also offer improvements during upswings pandemic activity.

Infectious disease modelling can serve as a powerful tool for situational awareness and decision support policy makers. However, COVID-19 efforts faced many challenges, from poor data quality to changing human behaviour. To extract practical insight the large body of literature available, we provide narrative review with systematic approach that quantitatively assessed prospective, data-driven studies in USA. We analysed 136 papers, focused on aspects models are essential have documented forecasting window, methodology, prediction target, datasets used, geographical resolution each study. also found fraction papers did not evaluate performance (25%), express uncertainty (50%), or state limitations (36%). remedy some these identified gaps, recommend adoption EPIFORGE 2020 model reporting guidelines creating an information-sharing system is suitable fast-paced infectious outbreak science.

Reluctance or refusal to get vaccinated, commonly known as Vaccine Hesitancy (VH), poses a significant challenge COVID-19 vaccination campaigns. Understanding the factors contributing VH is essential for shaping effective public health strategies. This study proposes novel framework combining machine learning with publicly available data generate proxy metric that evaluates dynamics of faster than currently used survey methods. The input descriptive classification models analyze wide array data, aiming identify key associated at county level in U.S. during pandemic (i.e., January October 2021). Both static and dynamic are considered. We use Random Forest classifier identifies political affiliation Google search trends most influencing behavior. model categorizes counties into five distinct clusters based on Cluster 1, low VH, consists mainly Democratic-leaning residents who, have longest life expectancy, college degree, highest income per capita, live metropolitan areas. 5, high predominantly Republican-leaning individuals non-metropolitan Individuals 1 more responsive policies.

This study compared estimates of the first-dose COVID-19 vaccination rates among Indian adults 2021 from large sample, Trends and Impact Survey (CTIS), small probability survey, Center for Voting Options Election Research (CVoter), against national benchmark data COVID Vaccine Intelligence Network. Notably, CTIS exhibits larger estimation error on average (0.37) CVoter (0.14). Additionally, we explored accuracy (regarding mean squared error) estimating successive differences (over time) subgroup (for females versus males) vaccine uptakes. Compared overall rates, targeting these alternative estimands comparing or relative two means increased effective sample size. These results suggest that Big Data Paradox can manifest countries beyond United States may not apply equally every estimand interest.
