Objectives Our objective was to review the literature on inferred duration of infectious period COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, and provide an overview variation depending methodological approach. Design Rapid scoping review. Literature with fixed search terms, up 1 April 2020. Central tendency parameter estimates for in (A) asymptomatic (B) symptomatic cases from (1) virological studies (repeated testing), (2) tracing (3) modelling...
Objectives The aim of this study was to determine the relative infectiousness asymptomatic SARS-CoV-2 infected persons compared with symptomatic individuals based on a scoping review available literature. Design Rapid peer-reviewed literature from 1 January 5 December 2020 using LitCovid database and Cochrane library. Setting International studies SARS-CoV-2. Participants Studies were selected for inclusion if they defined asymptomatics as separate cohort distinct presymptomatics provided...
Abstract Objective To estimate the proportion of pre-symptomatic transmission SARS-CoV-2 infection that can occur and timing relative to symptom onset. Setting/design Secondary analysis international published data. Data sources Meta-analysis COVID-19 incubation period a rapid systematic review serial interval generation time, which are separately. Participants Studies were selected for if they had transparent methods data provided enough information simulate full distributions or time....

Design Rapid scoping review. Literature with fixed search terms, up 1 st April 2020. Central tendency parameter estimates for in (a) asymptomatic (b) symptomatic cases from ( i ) virological studies (repeated testing), ii tracing iii) modelling were gathered. Narrative viral...
ABSTRACT Background Reliable estimates of the incubation period are important for decision making around control infectious diseases. Knowledge distribution can be used directly to inform decision-making or as inputs into mathematical models. Objectives The aim this study was conduct a rapid systematic review and meta-analysis periods COVID-19. Design Rapid observational research Data sources Publications on electronic databases PubMed, Google Scholar, MedRxiv BioRxiv were searched. search...
ABSTRACT Objectives The aim of this study was to conduct a scoping review estimates the relative infectiousness asymptomatic persons infected with SARS-CoV-2 compared symptomatic individuals. Design Rapid literature available until 8 th April 2020. Setting International studies on individuals Participants Studies were selected for inclusion if they defined asymptomatics as separate cohort distinct from pre-symptomatics and provided quantitative measure symptomatics. Primary outcome measures...
Norovirus is a significant hazard to consumers of shellfish, in particular oysters. Oysters grown waters contaminated with wastewater filter and accumulate norovirus particles, causing infection humans when the product consumed raw or lightly cooked. In European Union (EU) United States, bacterial detection criteria are used assess manage microbial risk shellfish. This regulatory framework effective managing risks associated microbiological contamination bivalve shellfish but not for...
Abstract Norovirus contamination of oysters is the lead cause non-bacterial gastroenteritis and a significant food safety concern for oyster industry. Here, norovirus reduction from Pacific ( Crassostrea gigas), contaminated in marine environment, was studied laboratory depuration trials two commercial settings. concentrations were measured digestive tissue before, during post-depuration using ISO 15216-1 quantitative real-time RT-PCR method. Results laboratory-based studies demonstrate that...
To determine the care pathways and implications of offering mothers choice external cephalic version (ECV) at term for singleton babies who present with an uncomplicated breech pregnancy versus assisted delivery or elective caesarean. A prospective observational audit to construct a decision analysis full presentations. The North Staffordshire NHS Trust. All women (n = 176) presented baby without complications during July 1995 June 1997. study determined compare outcome in terms costs cost...
Norovirus in oysters is a significant food safety risk. A recent ISO detection method allows for reliable and repeatable estimates of norovirus concentrations pooled samples, but there insufficient data to estimate distribution copies per animal from this. The spread accumulated across individual useful risk assessment models. Six sets thirty Crassostrea gigas were tested concentration levels by reverse-transcription quantitative PCR (RT-qPCR): three commercial harvest site, post-depuration....
Listeria monocytogenes is a pathogen of considerable public health importance with high case fatality. L. can grow at refrigeration temperatures and particular concern for ready-to-eat foods that require refrigeration. There substantial interest in conducting modeling shelf-life studies on monocytogenes, especially relating to storage temperature. Growth model parameters are generally estimated from constant-temperature growth experiments. Traditionally, first-order second-order (or primary...
Food-borne microbial illness contributes up to one third of global disease burden. The largest category food-borne is gastroenteritis, the majority which caused by enteric viruses. Viruses like these are transmitted food either waste-contaminated waters, or handling and transfer during processing. An important tool for reducing controlling risk analysis. This framework has been adopted globally manage risks associated with contamination in food. Several hundred assessments (MRAs) have...
Diarrhetic Shellfish Poisoning toxins (DSTs), originating from toxic phytoplankton, pose a significant risk to consumers when accumulated in shellfish. This study evaluates the effectiveness of EU regulations, which set maximum concentration OA toxin group at 160 µg/kg live mussels, protecting during Irish mussel consumption. A comprehensive exposure assessment was conducted for single meal scenario, incorporating mussels harvested various months account level variations. Regarding eating...
Abstract Soft fruits are at particular risk of contamination with enteric viruses such as Hepatitis A virus (HAV), E Virus (HEV), Norovirus (NoV), Human Adenovirus (HAdV) and Sapovirus (SaV). The aim this study was to investigate, for the first time, presence these biological agents in ready eat (RTE) berries point retail Ireland. sampling strategy designed which RTE fresh frozen strawberries raspberries were purchased from five retailers between May October 2018. Reverse Transcriptase...
This report summarises the outcomes from EFSA funded ListeriaPredict Partnering Project based on consortium's proposal of “Application novel predictive microbiology techniques to shelf-life studies Listeria monocytogenes in ready-to-eat foods (ListeriaPredict)” submitted under open call for partnering grant projects. The consortium consisted four partners, University College Dublin (Coordinator), Instituto Politécnico de Bragança, Istituto Zooprofilattico Sperimentale di Abruzzo e Molise and...
Analyses the implications of management labour for an organization undertaking accreditation exercise. Considers King's Fund Organizational Audit (KFOA) scheme, which is concerned with process and facilities, assesses quality hospital environment in health care product supplied. Concludes that, given current enthusiasm finding best practice ever-increasing number cost-effectiveness analyses therapeutic interventions, it seems somewhat contradictory that interventions cover whole are...
