“…In addition to bacterial infection, norovirus was the leading viral pathogen associated with foodborne illnesses, followed by hepatitis A virus, and only a small portion of the enteritis cases were due to other viruses [ 23 ]. AiV has never appeared in that report, thus supporting the present findings that the positive rate of antibodies in all age groups is far lower than the results of other countries that prefer raw seafood [ 21 , 22 ].…”

Aichi virus (AiV) belongs to the genus Kobuvirus of the family Picornaviridae; it is a single-stranded positive-sense RNA virus without an envelope. AiV causes acute gastroenteritis, abdominal pain, nausea, vomiting, and fever. Low incidence and high seroprevalence of AiV infections have been reported in several regions of the world; however, little was known on the prevalence of AiV infections in Taiwan. This study described the first two cases of AiV infection and analyzed AiV seroprevalence in Taiwan. A total of 700 sera were collected from a single hospital in southern Taiwan. The neutralization assay was employed to assess AiV neutralization antibodies in the serum. The test identified 48 positive cases, with a seroprevalence of 6.86%. Results also showed a gradual increase in AiV seroprevalence rate with age. Compared with other countries, Taiwan had a relatively low AiV seroprevalence, suggesting a low incidence of or sporadic AiV infections.

“…Foodborne disease is a global health problem, AiV is a foodborne pathogen and is closely related to diet and environmental hygiene [ 1 ]. Foodborne events suspected to be linked to the consumption of raw seafood have been reported [ 21 , 22 ]. The low seroprevalence of AiV in Taiwan may be due to the prevailing diet [ 23 ].…”

“…The syndromic surveillance system known as SurSaUD ® has already proven its benefit in rapidly detecting unusual variations in the number of ED and SOSMed visits, adequately monitoring changes in the variation of seasonal or unexpected outbreaks, and contributing to the impact assessment of events on the population [ 9 , 11 ]. Based on the automatic daily collection of individual data, the system was the first to monitor the spread of emergent pathologies such as COVID-19 in the population.…”

“…The system also collects mortality data from the civil status offices and electronic death certificates [6,7]. This non-specific surveillance aims to detect unexpected health events early on, monitor seasonal outbreaks, and assess outbreaks and their public health impact on the population [6,8,9]. SyS was already proven to adequately monitor For ED visits, a new ICD-10 code (U07.1) based on WHO coding recommendations for COVID-19 was added to existing codes in the software (B34.2, B97.2, and U04.9) (Table 1) [12].…”

Background The French syndromic surveillance (SyS) system, SurSaUD®, was one of the systems used to monitor the COVID-19 outbreak. Aim This study described the epidemiological characteristics of COVID-19-related visits to both emergency departments (EDs) and the network of emergency general practitioners known as SOS Médecins (SOSMed) in France from 17 February to 28 June 2020. Methods Data on all visits to 634 EDs and 60 SOSMed associations were collected daily. COVID-19-related visits were identified using ICD-10 codes after coding recommendations were sent to all ED and SOSMed doctors. The time course of COVID-19-related visits was described by age group and region. During the lockdown period, the characteristics of ED and SOSMed visits and hospitalisations after visits were described by age group and gender. The most frequent diagnoses associated with COVID-19-related visits were analysed. Results COVID-19 SyS was implemented on 29 February and 4 March for EDs and SOSMed, respectively. A total of 170,113 ED and 59,087 SOSMed visits relating to COVID-19 were recorded, representing 4.0% and 5.6% of the overall coded activity with a peak in late March representing 22.5% and 25% of all ED and SOSMed visits, respectively. COVID-19-related visits were most frequently reported for women and those aged 15–64 years, although patients who were subsequently hospitalised were more often men and persons aged 65 years and older. Conclusion SyS allowed for population health monitoring of the COVID-19 epidemic in France. As SyS has more than 15 years of historical data with high quality and reliability, it was considered sufficiently robust to contribute to defining the post-lockdown strategy.

“…Norovirus (NoV), rotavirus (RV), adenovirus (AdV), hepatitis A (HAV) and hepatitis E virus (HEV) are the causative agents of gastroenteritis, meningitis and hepatitis. They are all transmitted by the fecal-oral route and represent the viral pathogens of primary concern for waterborne and foodborne outbreaks, including those involving shellfish consumption [11][12][13][14][15][16]. Many reports informed on enteric virus contamination of shellfish products worldwide [17,18].…”

Contamination of bivalve mollusks with human pathogenic viruses represents a recognized food safety risk. Thus, monitoring programs for shellfish quality along the entire food chain could help to finally preserve the health of consumers. The aim of the present study was to provide up-to-date data on the prevalence of enteric virus contamination along the shellfish production and distribution chain in Sicily. To this end, 162 batches of mollusks were collected between 2017 and 2019 from harvesting areas, depuration and dispatch centers (n = 63), restaurants (n = 6) and retail stores (n = 93) distributed all over the island. Samples were processed according to ISO 15216 standard method, and the presence of genogroup GI and GII norovirus (NoV), hepatitis A and E viruses (HAV, HEV), rotavirus and adenovirus was investigated by real-time reverse transcription polymerase chain reaction (real-time-RT PCR), nested (RT)-PCR and molecular genotyping. Our findings show that 5.56% of samples were contaminated with at least one NoV, HAV and/or HEV. Contaminated shellfish were sampled at production sites and retail stores and their origin was traced back to Spain and several municipalities in Italy. In conclusion, our study highlights the need to implement routine monitoring programs along the whole food chain as an effective measure to prevent foodborne transmission of enteric viruses.
