During the COVID-19 pandemic, wastewater surveillance was used to monitor community transmission of SARS-CoV-2. As new genetic variants emerged, the need for timely identification of these variants in wastewater became an important focus. In response to increased reports of Omicron transmission across the United States, the Oklahoma Wastewater Surveillance team utilized allele-specific RT-qPCR assays to detect and differentiate variants, such as Omicron, from other variants found in wastewater in Oklahoma.

The COVID-19 pandemic halted progress in global vaccine coverage and disrupted routine childhood vaccination practices worldwide. While there is ample evidence of the vaccination decline experienced during the pandemic, it is less clear how low-income countries were affected. We executed a systematic review to synthesize the current literature on the impacts of routine childhood vaccinations in low-income countries from 1 January 2020 to 8 February 2023.

Article Synopsis
  • Tick-borne diseases (TBDs) in the US have more than doubled in the last 15 years, with Lyme disease, rickettsioses, and anaplasmosis being the most prevalent and leading to increased health issues.
  • A systematic review was conducted on the influence of climate change and other environmental factors on TBDs, analyzing studies from January 2018 to August 2023 across various US states.
  • Key findings indicate that environmental factors like climate, seasonality, and land use significantly affect the epidemiology of TBDs, highlighting the need for localized research to enhance prevention strategies.

Introduction: Fear of COVID-19 may differ for individuals with compromised health and those with unhealthy behaviors, placing them at greater risk. Based on previous analysis of academic medical center faculty and staff, the authors predicted that workers who were smokers/previous smokers would express the greater fear of COVID-19 relative to nonsmokers.

Methods: The present study used the Fear of COVID-19 Scale to assess fear among nonsmokers (n = 1,489) and smokers/previous smokers (n = 272) from a larger population of academic medical center members (N = 1,761).

The antidiabetic medication metformin has been proposed to be the first drug tested to target aging and extend healthspan in humans. While there is extensive epidemiological support for the health benefits of metformin in patient populations, it is not clear if these protective effects apply to those free of age-related disease. Our previous data in older adults without diabetes suggest a dichotomous change in insulin sensitivity and skeletal muscle mitochondrial adaptations after metformin treatment when co-prescribed with exercise.

SARS-CoV-2 was discovered among humans in late 2019 and rapidly spread across the world. Although the virus is transmitted by respiratory droplets, most infected persons also excrete viral particles in their feces. This fact prompted a range of studies assessing the usefulness of wastewater surveillance to determine levels of infection and transmission and produce early warnings of outbreaks in local communities, independently of human testing.

SARS-CoV-2 RNA detection in wastewater is being rapidly developed and adopted as a public health monitoring tool worldwide. With wastewater surveillance programs being implemented across many different scales and by many different stakeholders, it is critical that data collected and shared are accompanied by an appropriate minimal amount of metainformation to enable meaningful interpretation and use of this new information source and intercomparison across datasets. While some databases are being developed for specific surveillance programs locally, regionally, nationally, and internationally, common globally-adopted data standards have not yet been established within the research community.

An outbreak is defined as the occurrence of disease cases in excess of normal expectancy within a particular area and a given time. Foodborne outbreaks caused by gastrointestinal bacteria such as Salmonella Typhimurium are among the most commonly reported and most extensively investigated. The classic outbreak investigation follows a series of well-defined steps which lead to a faster confirmation of the source and hopefully preventing of further cases.

Global climate change is predicted to alter precipitation and temperature patterns across the world, affecting a range of infectious diseases and particularly foodborne infections such as Campylobacter. In this study, we used national surveillance data to analyse the relationship between climate and campylobacteriosis in Denmark, Finland, Norway and Sweden and estimate the impact of climate changes on future disease patterns. We show that Campylobacter incidences are linked to increases in temperature and especially precipitation in the week before illness, suggesting a non-food transmission route.

In industrialized countries, the leading cause of bacterial gastroenteritis is Campylobacter jejuni. However, outbreaks are rarely reported, which may reflect limitations of surveillance, for which molecular typing is not routinely performed. To determine the frequency of genetic clusters among patients and to find links to concurrent isolates from poultry meat, broiler chickens, cattle, pigs, and dogs, we performed whole-genome sequencing on 1,509 C.
