Recombinant Noroviruses Circulating in Spain from 2016 to 2020 and Proposal of Two Novel Genotypes within Genogroup I.
2022
Noroviruses are the leading cause of sporadic cases and outbreaks of viral gastroenteritis. For more than 20 years, most norovirus infections have been caused by the pandemic genotype GII.4, yet recent studies have reported the emergence of recombinant strains in many countries. In the present study, 4,950 stool samples collected between January 2016 and April 2020 in Valencia, Spain, from patients with acute gastroenteritis were analyzed to investigate the etiological agent. Norovirus was the most frequently detected enteric virus, with a positivity rate of 9.5% (471/4,950). Among 224 norovirus strains characterized, 175 belonged to genogroup II (GII) and 49 belonged to GI. Using dual geno…

Anisakid Nematodes and Potential Risk of Human Anisakiasis through the Consumption of Hake, Merluccius spp., Sold Fresh in Spanish Supermarkets
2022
Nematode parasite species belonging to the Anisakis simplex complex are the most important cause of human anisakiasis through the consumption of (mainly) undercooked, previously not frozen, or conveniently treated fish. In Spain, the consumption of hake has been recognized as an important source of this parasitosis. With the aim of shedding light on the risk factors that can influence the potential risk of human anisakiasis in Spain through the consumption of fresh hake sold by nationwide supermarket chains, a total of 536 small hake specimens belonging to the species Merluccius bilinearis caught off the Northeast American coasts and Merluccius merluccius caught in the Northeast Atlantic an…
Misidentification ofDiphyllobothriumSpecies Related to Global Fish Trade, Europe
2014
To the Editor: Diphyllobothriosis, infection by tapeworms of the genus Diphyllobothrium (Cestoda: Diphyllobothriidea) (1), is a well-known disease of humans. In Europe, infections caused by 3 species of Diphyllobothrium have recently been reported in humans: D. latum is considered to be the principal species infecting persons in Europe (1); 4 cases of D. dendriticum infection and 6 cases of D. nihonkaiense infection have also been reported (2,3). Except for those caused by D. latum, which is autochthonous in northeastern Europe and subalpine lakes, most of the cases in Europe have been imported or caused by consumption of fish imported from areas to which the parasites are endemic (1,3,4). …
Dolphin morbillivirus epizootic resurgence, Mediterranean Sea
2008
In July 2007, > 100 striped dolphins, Stenella coeruleoalba, were found dead along the coast of the Spanish Mediterranean. Of 10 dolphins tested, 7 were positive for a virus strain closely related to the dolphin morbillivirus that was isolated during a previous epizootic in 1990.

Epidemiology and molecular investigation of hepatitis C infection following holiday haemodialysis
2012
Background: Hepatitis C virus infection (HCV) is not infrequent among haemodialysis patients. Most published reports suggest that patient-to-patient spread, either directly or indirectly, is the most common mode of transmission in renal units. Aim: To investigate the source of an outbreak, and the route of transmission, of acute HCV infection in two Scottish patients occurring within eight weeks of receiving haemodialysis in the same unit while on holiday in Majorca. Methods: This was an international epidemiological and molecular investigation of HCV infection among a cohort of haemodialysis patients from nine countries. Findings: No further HCV-positive infections were observed among resi…
Is there a widespread clone of Serratia marcescens producing outbreaks worldwide?
2021
[Background]: Serratia marcescens frequently causes outbreaks in healthcare settings. There are few studies using high-throughput sequencing (HTS) that analyse S. marcescens outbreaks. We present the analysis of two outbreaks in neonatal intensive care units (NICUs) in hospitals from the Comunitat Valenciana (CV, Spain) and the impact of using different reference genomes.
Predicting critical illness on initial diagnosis of COVID-19 based on easily obtained clinical variables: development and validation of the PRIORITY …
2021
Objectives: We aimed to develop and validate a prediction model, based on clinical history and examination findings on initial diagnosis of coronavirus disease 2019 (COVID-19), to identify patients at risk of critical outcomes. Methods: We used data from the SEMI-COVID-19 Registry, a cohort of consecutive patients hospitalized for COVID-19 from 132 centres in Spain (23rd March to 21st May 2020). For the development cohort, tertiary referral hospitals were selected, while the validation cohort included smaller hospitals. The primary outcome was a composite of in-hospital death, mechanical ventilation, or admission to intensive care unit. Clinical signs and symptoms, demographics, and medical…
Health literacy: A crucial determinant of vaccination decision-making
2020
Our study exploring the influence of health literacy on influenza vaccination among pregnant women in Spain reflected how women with high health literacy were more likely to reject influenza vaccination than those with lower health literacy (Castro-Sánchez et al., 2018). Among the reasons for these women to reject the vaccine were feelings about its need, in isolation and compared with other immunizations, and claims of having received insufficient information. To mitigate such a gap, women with high health literacy would access a greater variety of information sources, including those promoting outlier or fringe opinions (Danchin et al., 2018, Vila-Candel et al., 2016b).
