Predicting Norovirus in England Using Existing and Emerging Syndromic Data: Infodemiology Study

Predicting Norovirus in England Using Existing and Emerging Syndromic Data: Infodemiology Study

A short-term forecasting model that can provide timely predictions of the number of norovirus reports would be helpful in planning and coping with winter pressures and mitigating the impacts of norovirus on the health service. Data were acquired from the UKHSA SGSS, which routinely collects information on infectious diseases in England. Weekly counts of norovirus laboratory reports were used as a proxy for norovirus activity.

Predicting Norovirus in the United States Using Google Trends: Infodemiology Study

Predicting Norovirus in the United States Using Google Trends: Infodemiology Study

Polymerase chain reaction and enzyme-linked immunosorbent assay are useful methods to diagnose norovirus infection [6,7]. Thus far, there have been no specific drugs to treat norovirus infection. In the prevention of norovirus, hand washing and disinfectants are important and effective methods. In addition, avoiding contaminated water and contaminated food in restaurants are useful methods to prevent norovirus. It is important to rapidly recognize and report norovirus infection.

Near-Real-Time Surveillance of Illnesses Related to Shellfish Consumption in British Columbia: Analysis of Poison Center Data

Near-Real-Time Surveillance of Illnesses Related to Shellfish Consumption in British Columbia: Analysis of Poison Center Data

Examples of harmful contaminants include norovirus, Vibrio parahaemolyticus (VP), and different toxins that can accumulate in bivalve shellfish during harmful algal blooms. Outbreaks related to all types have been reported in BC. In 2010, a norovirus outbreak caused 36 laboratory-confirmed illnesses among raw oyster consumers [33].

Performance of a Mobile Phone App-Based Participatory Syndromic Surveillance System for Acute Febrile Illness and Acute Gastroenteritis in Rural Guatemala

Performance of a Mobile Phone App-Based Participatory Syndromic Surveillance System for Acute Febrile Illness and Acute Gastroenteritis in Rural Guatemala

Similar to most LMICs, Guatemala has limited experience with participatory syndromic surveillance and relies almost entirely on passive, centralized surveillance systems to estimate disease burden, including for important emerging pathogens such as dengue virus and norovirus, two of the most common causes of fever and diarrhea, respectively [16-19].

An Ontology to Improve Transparency in Case Definition and Increase Case Finding of Infectious Intestinal Disease:  Database Study in English General Practice

An Ontology to Improve Transparency in Case Definition and Increase Case Finding of Infectious Intestinal Disease: Database Study in English General Practice

Less restrictive – more representative (of coding practice) diagnostic criteria would greatly increase, for example, their estimate of norovirus by 26% to 59/1000 (95% CI 52.32-64.98) person-years equating to 3.7 (3.3-4.1) million infections annually [3]. Reported incidence rates for IID vary between 0.5% and 20% annually in the developed world [4-9]. Variation can be greatly attributed to underreporting and data types used to calculate rates [10].

Identifying Potential Norovirus Epidemics in China via Internet Surveillance

Identifying Potential Norovirus Epidemics in China via Internet Surveillance

Norovirus, a single-stranded RNA virus of the Caliciviridae family, is a leading cause of infectious acute gastroenteritis worldwide across all age groups, particularly in health care and community settings [3,4]. In the United States, norovirus causes nearly 21 million cases of acute gastroenteritis annually, and nearly 50% of acute gastroenteritis occurrences across Europe were attributed to the norovirus infection [5,6].
