Seroprevalence of anti-HEV IgG in children
Background and objectives: Hepatitis E virus (HEV) can be considered an emerging zoonotic pathogen and is an important cause of acute viral hepatitis in high-income countries. Corsica has been identified as a hyperendemic region for HEV. We aimed to characterize the prevalence of IgG among children and estimate the annual force of infection of HEV. Methods: From April 2020 to June 2021, we collected 856 "residual sera" in 13 medical biology labor…
Eight Months of Serological Follow-Up of Anti-Sars-CoV-2 Antibodies in France
These results demonstrated that single infection does not confer effective protection against SARS-CoV-2
A Cross-Sectional Study of Exposure Factors Associated with Seropositivity for Sars-CoV-2 Antibodies during the Second Epidemic Wave among a Sample of the University of Corsica (France)
These results could be useful for SARS-CoV-2 prevention and control on university campuses
Impact of the Second Epidemic Wave of Sars-CoV-2
We aimed to use serological surveillance based on serial cross-sectional sampling of residual sera obtained from clinical laboratories to compare the differences in age and sex profiles of infected persons in the first and second waves of SARS-CoV-2 in Corsica, France. Residual sera were obtained, including samples from individuals of all ages collected for routine screening or clinical management by clinical laboratories. All the sera collected …
Are People Optimistically Biased about the Risk of Covid-19 Infection? Lessons from the First Wave of the Pandemic in Europe
Unrealistic optimism, the underestimation of one's risk of experiencing harm, has been investigated extensively to understand better and predict behavioural responses to health threats. Prior to the COVID-19 pandemic, a relative dearth of research existed in this domain regarding epidemics, which is surprising considering that this optimistic bias has been associated with a lack of engagement in protective behaviours critical in fighting twenty-f…
The representativeness of a European multi-center network for influenza-like-illness participatory surveillance
Existing demographic and national datasets allowed the quantification of the participation biases of a large cohort for influenza-like-illness surveillance in the general population. Significant differences were found between Influenzanet participants and the general population. The quantified biases need to be taken into account in the analysis of Influenzanet epidemiological studies and provide indications on populations groups that should be t…
Rates of immunization against pandemic and seasonal influenza in persons at high risk of severe influenza illness
Our study shows that influenza vaccination coverage among patients of the French Sentinelles general practitioners remains largely below the target of 75% defined by the 2004 French Public Health Law, and underscores the need for the implementation of public health interventions likely to increase vaccination uptake
Β-globin cluster haplotypes in normal individuals and β039-thalassemia carriers from Sardinia, Italy
Seven polymorphic sites in the beta-globin cluster in association with specific thalassemia mutations were analyzed in a sample from Sardinia, Italy. In order to verify previous works carried out on normal samples (beta(A)/beta(A)) and family studies on beta-thalassemia homozygotes individuals, the haplotype frequencies in both normal individuals (beta(A)/beta(A)) and beta(0)39-thalassemia carriers (beta(A)/beta0) were studied. In our work chromo…
Diversité de l'ADN mitochondrial et histoire du peuplement des îles San Pietro et San Antioco (Sardaigne-Italie)
Mitochondrial sequence variation in the Guahibo Amerindian population from Venezuela
New data were obtained on mitochondrial DNA (mtDNA) from Guahibo from Venezuela, a group so far not studied using molecular data. A population sample (n = 59) was analyzed for mtDNA variation in two control-region hypervariable segments (HV1 and HV2) by sequencing. The presence or absence of a 9-bp polymorphism in the COII/tRNA(Lys) region was studied by direct amplification and electrophoretic identification. Thirty-eight variable sites were det…
Genetic Characterization of the Historical Albanian Ethnic Minority of Calabria (Southern Italy)
Three historical ethnic minorities are present in Calabria: Albanians, Greeks, and Occitans. The Albanian ethnic minority is the more populous, having settled in Calabria between the 15th and 17th centuries, and these populations are now located in the provinces of Cosenza and Catanzaro. In the present study the Albanian population structure is analyzed based on the allele frequencies of six classic genetic markers: ACP, GC, PGM1, AK, ADA, and 6P…
