Increasing physical activity among children is a potentially important public health intervention. Quantifying the economic and effects of intervention would help decision makers understand its impact priority. Using computational simulation model that we developed to represent all US ages 8–11 years, estimated maintaining current levels (only 31.9 percent get twenty-five minutes high-calorie-burning three times week) result each year in net present value $1.1 trillion direct medical costs...
Vaccine hesitancy, the reluctance or refusal to receive vaccination, is a growing public health problem in United States and globally. State policies that eliminate nonmedical ("personal belief") exemptions childhood vaccination requirements are controversial, their effectiveness improve coverage remains unclear given limited rigorous policy analysis. In 2016, California (Senate Bill 277) eliminated from school entry requirements. The objective of this study was estimate association between...
Objectives: Although outbreaks of restaurant-associated foodborne illness occur periodically and make the news, a restaurant may not be aware cost an outbreak. We estimated this under varying circumstances. Methods: developed computational simulation model; scenarios varied outbreak size (5 to 250 people affected), pathogen (n = 15), type dining establishment (fast food, fast casual, casual dining, fine dining), lost revenue (ie, meals per illness), lawsuits legal fees, fines, insurance...
Asymptomatic dengue virus (DENV) infections have important public health implications but are challenging to identify. We performed a cross-sectional study of reverse transcription quantitative polymerase chain reaction on pooled sera asymptomatic individuals from the south coast Kenya at two time periods identify cases viremia. Among 2,460 samples tested in pools 9 or 10, we found only one positive case (0.04% incidence). Although pooling has potential be cost-effective and time-efficient...
Abstract Background Aedes aegypti is an efficient vector of several arboviruses public health importance, including Zika and dengue. Currently management the only available avenue for disease control. Development control strategies requires a thorough understanding ecology. In this study, we identified households that are consistently productive Ae. pupae determined ecological socio-demographic factors associated with persistence abundance in rural urban Kenya. Methods We collected...
This study uses US Immigration and Customs Enforcement (ICE) Health Service Corps data to describe incident cases outbreaks of influenza, varicella, mumps in 22 ICE detention centers between 2017 March 2020.
Background Many schools have been cutting physical education (PE) classes due to budget constraints, which raises the question of whether policymakers should require offer PE classes. Evidence suggests that can help address rising inactivity and obesity prevalence. However, it would be helpful determine if requiring is cost-effective. Methods We developed an agent-based model youth in Mexico City impact all offering on changes weight, weight-associated health conditions corresponding direct...
Despite the increasing burden of dengue in Kenya and Africa, introduction expansion virus region remain poorly understood. The objective this study is to examine genetic diversity evolutionary histories (DENV) serotypes 1 3 contextualize their circulation within dynamics broader African region. Viral RNA was extracted from samples collected a cohort febrile patients recruited at clinical sites 2013 2022. Samples were tested by polymerase chain reaction (PCR) for DENV presence. Five...
Since March 2020, SARS-CoV-2 has plagued the world with COVID-19 and individuals of all ages have experienced varying symptoms disease. Older adults were experiencing more severe disease compared to children prioritized by vaccination efforts. While biologic therapies vaccinations implemented, there changes in public health restrictions subsequent surges resulting infected children. During these was a rise different variants dominant variant initially alpha (B.1.1.7 other Pango lineages)...
Abstract Background Vaccine hesitancy in low vaccine coverage “hot spots” has led to recent outbreaks of vaccine-preventable diseases across the United States. State policies improve by restricting non-medical (personal belief) exemptions are heavily debated and their effectiveness is unclear due limited rigorous policy analysis. In 2016, a California (SB 277) eliminated from kindergarten requirements. To address ongoing debate on such policies, we performed quasi-experimental, controlled...
