Comparing susceptibility and contagiousness in concurrent outbreaks with a non-VOC and the VOC SARS-CoV-2 variant B.1.1.7 in daycare centers in Hamburg, Germany
We describe two outbreaks of SARS-CoV-2 in daycare centers in the metropolitan area of Hamburg, Germany. The outbreaks occurred in rapid chronological succession, in neighborhoods with a very similar sociodemographic structure, thus allowing for cross-comparison of these events. We combined classical and molecular epidemiologic investigation methods to study infection entry, spread within the facilities, and subsequent transmission of infections to households. Epidemiologic and molecular evidence suggests a superspreading event with a non-variant of concern (non-VOC) SARS CoV-2 strain at the root of the first outbreak. The...

Online ahead of print.ABSTRACTOn a livestock farm where antimicrobial administration and its history had been managed for prudent use of antimicrobials, we surveyed antibiotic-resistant Escherichia coli strains isolated from cow feces and the surrounding environment (i.e., rat and crow feces, and water samples from a drainage pit and wastewater processing tank) every month for 1 year. Two strains (1.7%) in cow feces were resistant to tetracycline, whereas all other strains were susceptible to all other antimicrobials. Among 136 strains isol...

Literature review and meta-analysis of gastric and intestinal bioaccessibility for nine inorganic elements in soils and soil-like media for use in human health risk assessment
Int J Hyg Environ Health. 2022 Jan 26;240:113929. doi: 10.1016/j.ijheh.2022.113929. Online ahead of print.ABSTRACTWhen soils become contaminated, a human health risk assessment (HHRA) is beneficial for determining whether identified contaminants of potential concern (COPCs) pose a risk to human health. In certain jurisdictions, when calculating doses from soil ingestion during the exposure assessment step of a HHRA, validated bioaccessibility methods may be used to accurately represent a contaminant's relative absorption factor (RAF). Where validated methods do not exist, risk assessors must either a) conduct their own lit...

Determination of a guidance value for the communication of individual-level biomonitoring data for urinary arsenic
CONCLUSION The range of guidance values obtained appears suitable for interpreting and communicating ILBD in any population biomonitoring studies in which background exposure is comparable to the North American and European context. Before selecting a single value within the proposed range, it will be important for Public Health officials to assess the possible consequences of this selection on the management and communication of the biomonitoring results.PMID:35085883 | DOI:10.1016/j.ijheh.2022.113927 (Source: International Journal of Hygiene and Environmental health)

Monitoring coliphages to reduce waterborne infectious disease transmission in the One Water framework
Int J Hyg Environ Health. 2022 Jan 20;240:113921. doi: 10.1016/j.ijheh.2022.113921. Online ahead of print.ABSTRACTCoastal waters, surface waters, and groundwater are impacted by wastewater and stormwater discharges, as well as agricultural flows containing animal waste and nutrients. A One Water approach posits that components of the water system have overlapping and interactive impacts on other aspects of the system, for which a comprehensive approach to water management is needed to further inform public health decisions. Current frameworks for monitoring wastewater effluent and recreational surface waters include the me...

Pathogen-specific response of infectious gastroenteritis to ambient temperature: National surveillance data in the Republic of Korea, 2015-2019
CONCLUSIONS: Cold temperature increased the risk of viral gastroenteritis and showed relatively long lagged effects. Hot temperature increased the risk of bacterial gastroenteritis and showed relatively short lagged effects.PMID:35065521 | DOI:10.1016/j.ijheh.2022.113924 (Source: International Journal of Hygiene and Environmental health)

Cross-sectional associations between serum PFASs and inflammatory biomarkers in a population exposed to AFFF-contaminated drinking water
CONCLUSIONS: We observed preliminary evidence of altered inflammatory profiles among adults with elevated serum concentrations of PFASs due to contaminated drinking water. Modifications to inflammatory pathways may be one mechanism by which PFAS exposures produce adverse health effects in humans, but this finding requires verification in longitudinal studies as well as phenotypic anchoring to immune function outcomes.PMID:35065522 | DOI:10.1016/j.ijheh.2021.113905 (Source: International Journal of Hygiene and Environmental health)
