Abstract We use COVID-19 case and mortality data from 1 February 2020 to 21 September a deterministic SEIR (susceptible, exposed, infectious recovered) compartmental framework model possible trajectories of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections the effects non-pharmaceutical interventions in United States at state level 22 through 28 2021. Using this model, projections critical driving covariates (pneumonia seasonality, mobility, testing rates mask per...
National rates of COVID-19 infection and fatality have varied dramatically since the onset pandemic. Understanding conditions associated with this cross-country variation is essential to guiding investment in more effective preparedness response for future pandemics.
Timely, accurate, and comprehensive estimates of SARS-CoV-2 daily infection rates, cumulative infections, the proportion population that has been infected at least once, effective reproductive number (R
Anemia is a globally widespread condition in women and associated with reduced economic productivity increased mortality worldwide. Here we map annual 2000-2018 geospatial estimates of anemia prevalence reproductive age (15-49 years) across 82 low- middle-income countries (LMICs), stratify by severity aggregate results to policy-relevant administrative national levels. Additionally, provide subnational disparity analyses comprehensive overview inequalities within these predict progress...
While much of the attention on COVID-19 pandemic was directed at daily counts cases and those with serious disease overwhelming health services, increasingly, reports have appeared people who experience debilitating symptoms after initial infection. This is popularly known as long COVID.
Cost-effectiveness analysis (CEA) is a well-known, but resource intensive, method for comparing the costs and health outcomes of interventions. To build on available evidence, researchers are developing methods to transfer CEA across settings; previous do not use all results nor quantify differences settings. We conducted meta-regression published CEAs human papillomavirus (HPV) vaccination effects factors at country, intervention, method-level, predict incremental cost-effectiveness ratios...
ABSTRACT BACKGROUND Social distancing mandates (SDM) have reduced health impacts from COVID-19 but also resulted in economic downturns that led many nations to relax SDM. Until deployment of an efficacious and equitable vaccine, intervention options reduce mortality minimize restrictive SDM are sought by society. METHODS A susceptible-exposed-infectious-recovered (SEIR) deterministic transmission model was parameterized with data on reported deaths, cases, select covariates predict...
