Background: Forecasting of COVID-19 cases daily and weekly has been one of the challenges posed to governments and the health sector globally. To facilitate informed public health decisions, the concerned parties rely on short-term daily projections generated via predictive modeling. We calibrate stochastic variants of growth models and the standard susceptible-infectious-removed model into 1 Bayesian framework to evaluate and compare their short-term forecasts.
Results: We implement rolling-origin cross-validation to compare the short-term forecasting performance of the stochastic epidemiological models and an autoregressive moving average model across 20 countries that had the most confirmed COVID-19 cases as of August 22, 2020.
Conclusion: None of the models proved to be a gold standard across all regions, while all outperformed the autoregressive moving average model in terms of the accuracy of forecast and interpretability.

Household transmission of SARS-CoV-2 in five US jurisdictions: Comparison of Delta and Omicron variants.
PLoS One

COVID-19 Response Team, Centers for Disease Control and Prevention, Atlanta, Georgia, United States of America.
Households are a significant source of SARS-CoV-2 transmission, even during periods of low community-level spread. Comparing household transmission rates by SARS-CoV-2 variant may provide relevant information about current risks and prevention strategies. This investigation aimed to estimate differences in household transmission risk comparing the SARS-CoV-2 Delta and Omicron variants using data from contact tracing and interviews conducted from November 2021 through February 2022 in five U.

For patients hospitalized with COVID-19, delirium is a serious and under-recognized complication, and people experiencing homelessness (PEH) may be at greater risk. This retrospective cohort study compared delirium-associated risk factors and clinical outcomes between PEH and non-PEH. This study used patient records from 154 hospitals discharged from 2020-2021 from the Texas Inpatient Public Use Data file.

This study aims to analyze the diagnostic readiness to Covid-19 and the genomic surveillance of SARS-CoV-2 in Brasília, the capital of Brazil. This is a retrospective, cross-sectional study, with data from: cases/deaths-Ministry of Health; RT-PCR analyses Brasília Central Public Health Laboratory (LACEN); genomics-Global Initiative on Sharing All Influenza Data (GISAID). It was found that in March 2021, with the Gamma variant was predominant, RT-PCR diagnostic tests administered by LACEN reached their peak, followed by a reduction, possibly due to the start of vaccination.

Patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) progressing after chimeric antigen receptor T-cell therapy (CAR T) have dismal outcomes. The prespecified post-CAR T expansion cohort of the ELM-1 study investigated the efficacy and safety of odronextamab, a CD20×CD3 bispecific antibody, in patients with disease progression after CAR T. Sixty patients received IV odronextamab weekly for 4 cycles followed by maintenance until progression.

Background: The COVID-19 pandemic has significantly altered the etiological spectrum and epidemiological characteristics of pediatric respiratory diseases, and a profound understanding of these changes is crucial for guiding clinical treatment. The purpose of this study is to analyze the etiological patterns and epidemiological features of pathogens in bronchoalveolar lavage fluid (BALF) from children with pediatric lower respiratory tract infections (LRTIs) after the COVID-19 pandemic, with the aim of providing effective therapeutic evidence for clinical practice.
Methods: This study enrolled pediatric patients diagnosed with LRTIs who were treated and underwent BALF pathogen detection at our hospital from June 1, 2023, to June 1, 2024.
