The coronavirus disease 2019 (COVID-19) pandemic has disrupted in-person learning in the United States, with approximately one half of all students receiving online-only instruction since March 2020.*Discontinuation schooling can result many hardships (1) and disproportionately affects families lower socioeconomic status (2).Current evidence suggests that transmission SARS-CoV-2, virus causes COVID-19, kindergarten through grade 12 (K-12) schools might not significantly contribute to...
Male patients ages 12-17 years have an elevated risk of mRNA vaccination-associated myo/pericarditis. A risk-benefit analysis first and second doses vaccination in adolescent boys by health status history SARS-CoV-2 infection has not been performed.
In 2022, students at North American universities with third-dose COVID-19 vaccine mandates risk disenrolment if unvaccinated. To assess the appropriateness of booster in this age group, we combine empirical risk-benefit assessment and ethical analysis. prevent one hospitalisation over a 6-month period, estimate that 31 207–42 836 young adults aged 18–29 years must receive third mRNA vaccine. Booster are expected to cause net harm: per prevented, anticipate least 18.5 serious adverse events...
Patient visitor restrictions were implemented in unprecedented ways during the COVID-19 pandemic and included bans on any visitors to dying patients separating mothers from infants. These without high quality evidence they would be beneficial harms patients, families medical personnel often immediately clear. Evidence has also accumulated finding strict accompanied by long-term individual societal consequences. We highlight numerous examples of that enacted pandemic, including some continue...
Postpandemic surveillance data on coronavirus disease 2019 (COVID-19) infections may help inform future public health policies regarding severe acute respiratory syndrome 2 (SARS-CoV-2) testing, vaccinations, or other COVID-19 measures. We estimate the total SARS-CoV-2 in Austria after end of pandemic from wastewater and utilize these estimates to calculate average national levels infection protection death protection. estimated (5 May 2023, per World Health Organization) up 2024 using a...
Background: Observational studies may over- or under-estimate SARS-CoV-2 vaccine effectiveness (VE) depending on whether healthier (i.e. healthy effect (HVE)) more ill individuals are preferentially vaccinated. To evaluate this issue, we compared non-COVID-19, all-cause, cancer and COVID-19 mortality in vaccinated versus unvaccinated individuals. Methods: This is a nationwide retrospective observational study the entire adult population Austria with previously documented infection follow-up...
To determine the prevalence of amblyopia in Denmark before and after initiation Danish national preschool vision screening programme.In a population-based cross-sectional study, 3826 participants General Suburban Population Study (GESUS) aged 20 years older from rural municipality received complete general health examination an ophthalmological interview examination. This study included comprehensive ophthalmologic interview, measurement best corrected visual acuity (BCVA) each eye,...
Students at North American universities risk disenrollment due to third dose COVID-19 vaccine mandates. We present a risk-benefit assessment of boosters in this age group and provide five ethical arguments against estimate that 22,000 - 30,000 previously uninfected adults aged 18-29 must be boosted with an mRNA prevent one hospitalisation. Using CDC sponsor-reported adverse event data, we find booster mandates may cause net expected harm: per hospitalisation prevented young adults,...
ABSTRACT Objectives Establishing the rate of post-vaccination cardiac myocarditis in 12-15 and 16-17-year-old population context their COVID-19 hospitalization risk is critical for developing a vaccination recommendation framework that balances harms with benefits this patient demographic. Design, Setting Participants Using Vaccine Adverse Event Reporting System (VAERS), retrospective epidemiological assessment reviewed reports filed between January 1, 2021, June 18, among adolescents ages...
Rapid antigen testing continues to be broadly recommended across the world for prevention of transmission SARS-CoV-2. We explore existing recommendations in United States, evidence decreasing diagnostic reliability individual tests and potential benefits harms non-targeted testing. Recent research has found multiple commonly-used rapid now have sensitivities below 30%, with at or near 0% first 48 hours infection, using polymerase chain reaction (PCR) test positivity as gold standard....
Objective To determine the number of tweets discussing risk Mpox to children and young people in school (1) accuracy, (2) for inaccurate tweets, if was minimised or exaggerated (3) describe characteristics accounts which contained accurate versus information. Design Retrospective observational study. Setting Twitter advanced search January 2023 spanning 18 May 2022–19 September 2022. Participants Accounts labelled as: MD, DO, nurse, pharmacist, physical therapist, other healthcare provider,...
Abstract Background We aimed to evaluate the effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations in previously SARS-CoV-2–infected adults general population Austria during Delta wave and with extended follow-up. Methods In a nationwide retrospective cohort study, we calculated age-, sex-, nursing home residency–adjusted Cox proportional hazard ratios (HRs) disease 2019 (COVID-19) deaths, SARS-CoV-2 infections, non-COVID-19 deaths from 1 October 31...

This observational study evaluated the impact of return-to-play protocols to prevent transmission SARS-CoV-2 in a youth ice hockey programme Virginia Beach, Virginia.Following an outbreak November 2020, COVID-19 Response Team epidemiological data identify dynamics and develop enhanced transmission. During subsequent 18-week period, incident cases were investigated likely source; testing, quarantine isolation recommendations provided families accordance with Centers for Disease Control...
Background: The Centers for Disease Control and Prevention (CDC) has been a major source of information during the COVID-19 pandemic, guiding policies practices in many aspects life. As such, it is imperative that be free errors, or, if errors are made, they corrected quickly. Methods: We sought to compile instances numerical statistical made by CDC pandemic reviewing publications, press releases, interviews, meetings, Twitter accounts. Further, we catalogued mortality data from both...
Purpose: To examine the frequency and causes of visual impairment (VI) in a select population Danish adults.Methods: A total 3843 adults aged 20–94 years from General Suburban Population Study (GESUS) were included population-based, cross-sectional ophthalmological study, Rural Eye (DRES). All DRES participants received comprehensive general health examination preceding their eye examination, including measurement best-corrected acuity (BCVA) for each eye, bilateral 45° retinal fundus...
