RESUMO
Malaria remains one of the most important infectious diseases globally due to its high incidence and mortality rates. The influx of infected cases from endemic to non-endemic malaria regions like Europe has resulted in a public health concern over sporadic local outbreaks. This is facilitated by the continued presence of competent Anopheles vectors in non-endemic countries.We modelled the potential distribution of the main malaria vector across Spain using the ensemble of eight modelling techniques based on environmental parameters and the Anopheles maculipennis s.l. presence/absence data collected from 2000 to 2020. We then combined this map with the number of imported malaria cases in each municipality to detect the geographic hot spots with a higher risk of local malaria transmission.The malaria vector occurred preferentially in irrigated lands characterized by warm climate conditions and moderate annual precipitation. Some areas surrounding irrigated lands in northern Spain (e.g. Zaragoza, Logroño), mainland areas (e.g. Madrid, Toledo) and in the South (e.g. Huelva), presented a significant likelihood of A. maculipennis s.l. occurrence, with a large overlap with the presence of imported cases of malaria.While the risk of malaria re-emergence in Spain is low, it is not evenly distributed throughout the country. The four recorded local cases of mosquito-borne transmission occurred in areas with a high overlap of imported cases and mosquito presence. Integrating mosquito distribution with human incidence cases provides an effective tool for the quantification of large-scale geographic variation in transmission risk and pinpointing priority areas for targeted surveillance and prevention.

Introducción: El VIH sigue representando un problema de gran relevancia para la salud pública en España. El objetivo de este estudio es realizar un análisis que permita conocer en profundidad los recursos, cuidados clínicos y la gestión durante las fases de diagnóstico, seguimiento y tratamiento de la infección por el VIH en España. Métodos: En la primera fase un comité científico multidisciplinar diseñó una herramienta de recogida de información, en forma de encuesta. En la segunda fase, realizada en las comunidades autónomas de Andalucía, Cataluña y La Rioja, un grupo multidisciplinar de 42 expertos, representantes de la administración pública, perfiles clínicos y representantes de las ONG en el ámbito del VIH contestaron a la encuesta. Resultados: La valoración de los recursos destinados al VIH es en general positiva. En el diagnóstico los expertos consideraron que existía una buena coordinación entre atención primaria y hospitalaria. Con respecto al tratamiento las valoraciones han reflejado una buena opinión sobre la conciliación terapéutica y adherencia, y una valoración negativa sobre la evaluación de las interacciones entre medicamentos con el tratamiento antirretroviral. Sobre el seguimiento, la percepción expresada fue dispar con respecto a la coordinación entre atención hospitalaria y primaria y sobre la adaptación de los cuidados a la cronicidad, envejecimiento, fragilidad, salud mental y los procesos oncológicos. Conclusión: Existen determinados procesos que pueden ser mejorados en relación con el manejo de la infección de las personas con VIH en España, incluyendo protocolos de seguimiento y coordinación entre atención primaria y hospitalaria en el tratamiento y seguimiento de la enfermedad.(AU)
Introduction: HIV continues to represent a problem of great relevance for public health in Spain. This study aims to carry out an analysis that will provide in-depth knowledge of the resources, clinical care, and management during the diagnosis, follow-up, and treatment phases of HIV infection in Spain. Methods: In the first phase, a multidisciplinary Scientific Committee designed an information collection tool in the form of a survey. In the second phase, carried out in the autonomous communities of Andalusia, Catalonia, and La Rioja, a multidisciplinary group of 42 experts, representatives of the public administration, clinical profiles, and representatives of NGOs in the field of HIV answered the survey. Results: The assessment of HIV resources is generally positive. As regards diagnosis, the experts considered that there was good coordination between primary and hospital care. Regarding treatment, the evaluations reflected good opinions on therapeutic conciliation and adherence, with a negative opinion in the evaluation of drug interactions with antiretroviral treatment. Regarding follow-up, the perception expressed was disparate concerning the coordination between hospital and primary care as well as the adaptation of care to chronicity, aging, fragility, mental health, and oncological processes. Conclusion: There are certain processes that can be improved in the management of HIV infection in people with HIV in Spain, including protocols for follow-up and coordination between primary and hospital care in the treatment and follow-up of the disease.(AU)

In Spain, as in other countries, the spectrum of tick-borne diseases and their number have increased in recent years. The tick identification, at species level, can be challenging outside research centers although this information is very usufull for decisions making. The performance of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) in tick identification of specimens collected from patients have been seldomly reported. The aim of the present study was to desing a protein-extraction protocol and build a tick-legs reference spectra. This protocol was then validated using specimens from both patients and non-patient sources. Nine species of ticks that usually bites humans in Spain were included: Dermacentor marginatus, Dermacentor reticulatus, Haemaphysalis punctata, Hyalomma lusitanicum, Hyalomma marginatum, Ixodes ricinus, Rhipicephalus bursa, Rhipicephalus pusillus and Rhipicephalus sanguineus sensu lato. Other less-frequent biting species were also included: Haemaphysalis inermis, Haemaphysalis concinna, Hyalomma scupense, Ixodes frontalis, Ixodes hexagonus, and Argas sp. specimens were identified by PCR and sequencing of a fragment of the 16S rRNA gene of ticks. In the tests performed with non-patient collected specimens, a 100% correlation was observed between molecular methods and MS, while in the tests performed with ticks collected from patients a 92.59% correlation was observed. Misidentification was observed only in two of I. ricinus nymphs (identified as Ctenocephalides felis). Therefore, mass- spectrometry can be confidently used as a tick identification tool in a hospital setting for the rapid identification of tick vectors.

BACKGROUND: Diagnosis of undifferentiated non-malaria fevers (NMF) in returning travellers is a great challenge. Currently, there is no consensus about the use of empirical antibiotics in returning travellers with undifferentiated NMF. Although studies in endemic areas showed that a wide range of pathogens implicated in undifferentiated NMF are treatable with doxycycline, the role of doxycycline in returning travellers with fever still has to be explored. METHODS: Prospective European multicentre cohort study of febrile international travellers (November 2017-November 2019). Immunological and molecular diagnostic techniques for doxycycline responding illnesses (DRI) agents such as Anaplasma phagocytophilum, spotted fever group Rickettsia spp., typhus group Rickettsia spp., Coxiella burnetii, Bartonella spp., Orientia tsutsugamushi, Borrelia miyamotoi, Borrelia recurrentis and Leptospira spp. were systematically performed in all patients with undifferentiated NMF. We estimated the prevalence and predictive factors of DRI in returning travellers with undifferentiated NMF. RESULTS: Among 347 travellers with undifferentiated NMF, 106 (30·5%) were finally diagnosed with DRI. Only 57 (53·8%) of the 106 DRI infections were diagnosed by the standard of care. The main causes of DRI were: 55 (51·9%) Rickettsia spp., 16 (15·1%) C. burnetii; 15 (14·2%) Bartonella spp.; 13 (12·3%) Leptospira spp. and 10 (9·5%) A. phagocytophilum. The only predictive factor associated with DRI was presenting an eschar (aOR 39·52, 95%CI 4·85-322·18). Features of dengue such as retro-orbital pain (aOR 0·40, 95%CI 0·21-0·76) and neutropenia (aOR 0·41, 95%CI 0·21-0·79) were negatively associated with DRI. CONCLUSIONS: Although DRI are responsible for 30% of undifferentiated NMF cases in travellers, those are seldom recognized during the first clinical encounter. Empirical treatment with doxycycline should be considered in returning travellers with undifferentiated fever and negative tests for malaria and dengue, particularly when presenting severe illness, predictive factors for rickettsiosis or no features of dengue.

Mermithid nematodes are considered a promising biological control agent to reduce the population density of different blood-feeding vectors, i.e. black flies (Diptera: Simuliidae), which are important pests of medical and veterinary interest worldwide. Immature larvae of black flies were collected in a rill from La Rioja (Northern Spain) in the summer of 2016. Isomermis lairdi Mondet, Poinar & Bernadou, 1977 (Nematoda: Mermithidae) was found parasitizing eleven specimens of Simulium cryophilum s.l. (Rubtsov, 1959) (prevalence of 52%), which represent the first record of this nematode for Spain and the second for Europe. The confirmation of the nematode and the black fly species was carried out by both morphological and molecular approaches using the 18S ribosomal RNA and the cytochrome c oxidase subunit I genes. Phylogenetic analyses indicated that the collected specimens were Isomermis lairdi (99.4-99.9% identity with homologues from Africa) with a sequence divergence of 0.2%. The role of Isomermis lairdi as an alternative tool in the biological control of black flies in Spain should be further explored.

The impact of the SARS-CoV-2 pandemic on wildlife is largely unevaluated, and extended surveillance of animal species is needed to reach a consensus on the role of animals in the emergence and maintenance of SARS-CoV-2. This infection has been detected in farmed and domestic animals and wild animals, mainly in captivity. The interactions or shared resources with wildlife could represent a potential transmission pathway for the SARS-CoV-2 spill over to other wild species and could lead to health consequences or the establishment of new reservoirs in susceptible hosts. This study evaluated the presence of SARS-CoV-2 in European mink (Mustela lutreola) and American mink (Neogale vison) in Spain by enzyme-linked immunosorbent assay (ELISA) using the receptor binding domain (RBD) of Spike antigen in serum samples and/or by RT-qPCR assays in oropharyngeal and rectal swabs. From January 2020 to February 2022, a total of 162 animals (127 European mink and 35 American mink) with no evidence of SARS-CoV-2 infection were included in the study. Antibodies against the SARS-CoV-2 were not found in the serum samples analysed (n = 126), nor was the virus amplified by RT-qPCR (n = 160 swabs). Our results suggest that the potential role of wild mink and the European mink bred in captivity and released to the wild as dispersers of SARS-CoV-2 is so far low. However, wildlife surveillance for early detection of human and animal risks should be continued. In this sense, epidemiological monitoring measures, including serology and molecular analysis, are necessary.
RESUMO
The main objective was to evaluate the viability of the SARS-CoV-2 viral particles excreted in stools. In addition, we aimed to identify clinical factors associated with the detection of SARS-CoV-2 RNA in feces, and to determine if its presence is associated with an unfavorable clinical outcome, defined as intensive care unit (ICU) admission and/or death. A prospective multicenter cohort study of COVID-19 adult patients, with confirmed SARS-CoV-2 infection by RT-PCR assay in nasopharyngeal (NP) swabs admitted to four hospitals in Spain, from March 2020 to February 2021. Sixty-two adult COVID-19 patients had stool samples collected at admission and/or during the follow up, with a total of 79 stool samples. SARS-CoV-2 RNA was detected in stool samples from 27 (43.5%) out of the 62 patients. Replicative virus, measured by the generation of cytopathic effect in cell culture and subsequent RT-PCR confirmation of a decrease in the Ct values, was not found in any of these stool samples. Fecal virus excretion was not associated with the presence of gastrointestinal symptoms, or with differences in the evolution of COVID-19 patients. Our results suggest that SARS-CoV-2 replicative capacity is null or very limited in stool samples, and thus, the fecal-oral transmission of SARS-CoV-2 as an alternative infection route is highly unlikely. In our study, the detection of SARS-CoV-2 RNA in feces at the beginning of the disease is not associated with any clinical factor nor with an unfavorable clinical outcome.

BACKGROUND: Although tick-borne pathogens have been reported as an important cause of imported fever, the incidence of Anaplasma phagocytophilum, the causative agent of human granulocytic anaplasmosis (HGA), in travellers is unknown. METHODS: We conducted a prospective cohort study to investigate the aetiologies of fever in returning travellers (November 2017-July 2019). Polymerase chain reaction for msp2 gene amplification and indirect immunofluorescence assay for A. phagocitophilum were performed in all returning travellers with undifferentiated non-malarial fever. RESULTS: Among 141 travellers included, 8 patients were diagnosed with probable or confirmed HGA. The overall incidence rate of HGA was 19.9 cases/1000 person-week of travel. The main destination of travel was Asia, accounting for 62.5% patients with HGA. Co-infections were found in 37.5% of patients with HGA. CONCLUSIONS: Diagnosis of HGA and empirical treatment with doxycycline should be considered in travellers with fever.

RESUMO
Viral infections of the nervous system represent a major health problem. It is estimated that the incidence of viral meningitis in the general population ranges from 5-17 cases per 100,000 inhabitants per year in developed countries. This heading encompasses highly varied clinical pictures, ranging from meningitis to encephalitis. This article presents the agents involved in our environment and discusses their expressiveness. In immunocompetent patients, the course of these infections is usually benign. Nucleic acid amplification techniques are the gold standard for their etiological diagnosis. The introduction of polymerase chain reaction and serological diagnosis of the main arboviruses has increased the diagnostic capabilities in a wide spectrum of these clinical entities.

Hepatitis E virus (HEV) infection is one of the main causes of acute hepatitis in both developed and developing countries. This infectious disease has a high prevalence and incidence in Europe. HEV infection has a greater clinical impact in vulnerable populations, such as immunosuppressed patients, pregnant women and patients with underlying liver disease. Therefore, the Study Group for Viral Hepatitis (Grupo de Estudio de Hepatitis Víricas, GEHEP) of the Spanish Society of Infectious Diseases and Clinical Microbiology (Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica, SEIMC) believed it very important to prepare a consensus document to help in decision-making regarding diagnosis, clinical and therapeutic management, and prevention of HEV infection
La infección por el virus de la hepatitis E (VHE) es una de las principales causas de hepatitis aguda tanto en países desarrollados como en vías de desarrollo, situándose como una enfermedad infecciosa de alta prevalencia e incidencia en Europa. La infección por el VHE tiene mayor impacto clínico en poblaciones especialmente vulnerables, como pacientes inmunodeprimidos, mujeres embarazadas y pacientes con hepatopatía base. Por todo ello, desde el Grupo de Estudio de las Hepatitis Víricas (GeHEP) de la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC) se considera de gran relevancia la elaboración de un Documento de Consenso que sirva de ayuda en la toma de decisiones sobre el diagnóstico, manejo clínico-terapéutico y la prevención de la infección por el VHE

Mosquitoes are important to public and animal health due to their capacity to transmit diseases. Since the Zika virus was declared a pandemic by the WHO in 2016, and it has been recorded in different regions of Mediterranean Area (included Spain), the Government of La Rioja (Northern Spain) through the Center of Rickettsiosis and Arthropod-Borne Diseases, implemented an entomological surveillance programme of mosquitoes in La Rioja and in a close area of Navarra. This surveillance extended to some of the pathogens that they can transmit. Here we describe the framework of the initial surveillance programme for the detection of mosquitoes and associated human pathogens. We outline the benefits and the limitation of the programme to date, and explore how greater benefits can be achieved, for example using a One Health approach. Entomological surveillance has been carried out with BG-Sentinel traps, human bait technique and other methods such as collecting adults in resting places or immature stages by dipping in several wetlands. Since Aedes albopictus, vector of arbovirus such as Dengue, Chikungunya, and Zika, has not been detected yet in the region, the entomological programme included the surveillance of this exotic species using ovitraps in the most important cities. Morphological identification was supported using the mitochondrial cytochrome C oxidase subunit I and the internal transcribed spacer 2 genes analysis. In 2016 and 2017, more than 6,000 mosquitoes were collected. The mosquito's community included 21 species associated with six genera: Anopheles (n = 4), Aedes (n = 5), Culex (n = 6), Culiseta (n = 4), Uranotaenia (n = 1) and Coquillettidia (n = 1). Eleven species represent new records for La Rioja and Navarra regions. Several species were collected biting humans and a great proportion of the sampled mosquito population are competent vectors of several pathogens, such as West Nile virus. Sequences closely related to mosquito-only flavivirus have been detected in 0.34% of analysed pools. At the same time, the epidemiological surveillance emphasis is placed in the early detection of mosquito-borne diseases in primary health and emergency services. The surveillance programme represents a relevant and necessary assessment of the risk of pathogen transmission in a region, and it allows for the establishment of the appropriate preventive measures.
RESUMO
The presence of metabolic syndrome (MS) per se or its separated components in HIV-infected patients contributes to an accelerated aging and increased cardiovascular risk. Gut microbiota (GM) dysbiosis has been linked with chronic inflammation associated with MS in a general non-infected population. However, no studies concerning GM have been performed in HIV-infected patients with MS. The aim of this study was to analyze bacterial translocation, inflammation, and GM composition in HIV-infected patients with and without MS. A total of 51 HIV-infected patients were recruited and classified according to the presence of MS (40 patients without MS and 11 with MS). Markers of bacterial translocation, inflammation, and cardiovascular risk were measured and GM was analyzed using 16S rRNA gene deep sequencing. No differences were observed among both HIV-infected groups in the bacterial translocation markers LBP and sCD14. A tendency to increase the inflammatory markers IL-6 (p = 0.069) and MCP-1 (p = 0.067) was observed in those patients suffering from MS. An increase in the cardiovascular risk markers PAI-1 (p = 0.007) and triglycerides/HDL cholesterol ratio (p < 0.0001) was also found in the MS group. No significant changes were observed at phylum level although a decrease in the abundance of seven genera and seven bacterial species, including some anti-inflammatory bacteria, was observed in HIV-infected patients with MS. To summarize, the presence of MS was not accompanied by major changes in GM, although the reduction observed in some anti-inflammatory bacteria may be clinically useful to develop strategies to minimize inflammation and its future deleterious consequences in these HIV-infected patients.
