Detection of dengue in German tourists returning from Ibiza, Spain, related to an autochthonous outbreak, August to October 2022.

In February 2023, German public health authorities reported two dengue cases (one confirmed, one probable) and four possible cases who travelled to Ibiza, Spain, in late summer/autumn 2022; the infection was probably acquired through mosquito bites. Case 1 visited Ibiza over 1 week in late August with two familial companions; all three developed symptoms the day after returning home. Only Case 1 was tested; dengue virus (DENV) infection was confirmed by presence of NS1 antigen and IgM antibodies. Case 2 travelled to Ibiza with two familial companions for 1 week in early October, and stayed in the same town as Case 1. Case 2 showed symptoms on the day of return, and the familial companions 1 day before and 3 days after return; Case 2 tested positive for DENV IgM. The most probable source case had symptom onset in mid-August, and travelled to a dengue-endemic country prior to a stay in the same municipality of Ibiza for 20 days, until the end of August. Dengue diagnosis was probable based on positive DENV IgM. Aedes albopictus, a competent vector for dengue, has been present in Ibiza since 2014. This is the first report of a local dengue transmission event on Ibiza.

Influenza A(H5N1) detection in two asymptomatic poultry farm workers in Spain, September to October 2022: suspected environmental contamination.

In autumn 2022, the Spanish Influenza National Reference Laboratory (NRL) confirmed the detection of influenza A(H5N1) in samples from two asymptomatic workers linked to an outbreak in a poultry farm in Spain. Nasopharyngeal swabs were taken according to a national screening protocol for exposed workers. Absence of symptoms, low viral load and negative serology in both workers suggested environmental contamination. These findings motivated an update of the early detection strategy specifying timing and sampling conditions in asymptomatic exposed persons.

Lifting COVID-19 mitigation measures in Spain (May-June 2020).

Introduction: The state of alarm was declared in Spain due to the COVID-19 epidemic on March 14, 2020, and established population confinement measures. The objective is to describe the process of lifting these mitigation measures. Methods: The Plan for the Transition to a New Normality, approved on April 28, contained four sequential phases with progressive increase in socio-economic activities and population mobility. In parallel, a new strategy for early diagnosis, surveillance and control was implemented. A bilateral decision mechanism was established between the Spanish Government and the autonomous communities (AC), guided by a set of qualitative and quantitative indicators capturing the epidemiological situation and core capacities. The territorial units were established ad-hoc and could be from Basic Health Zones to entire AC. Results: The process run from May 4 to June 21, 2020. AC implemented plans for reinforcement of core capacities. Incidence decreased from a median (50% of territories) of 7.4 per 100,000 in 7 days at the beginning to 2.5 at the end. Median PCR testing increased from 53% to 89% of suspected cases and PCR total capacity from 4.5 to 9.8 per 1000 inhabitants weekly; positivity rate decreased from 3.5% to 1.8%. Median proportion of cases with traced contacts increased from 82% to 100%. Conclusion: Systematic data collection, analysis, and interterritorial dialogue allowed adequate process control. The epidemiological situation improved but, mostly, the process entailed a great reinforcement of core response capacities nation-wide, under common criteria. Maintaining and further reinforcing capacities remained crucial for responding to future waves.

Introducción: El 14 de marzo de 2020 España declaró el estado de alarma por la pandemia por COVID-19 incluyendo medidas de confinamiento. El objetivo es describir el proceso de desescalada de estas medidas. Métodos: Un plan de transición hacia una nueva normalidad, del 28 de abril, incluía 4 fases secuenciales incrementando progresivamente las actividades socioeconómicas y la movilidad. Concomitantemente, se implementó una nueva estrategia de diagnóstico precoz, vigilancia y control. Se estableció un mecanismo de decisión bilateral entre Gobierno central y comunidades autónomas (CCAA), guiado por un panel de indicadores cualitativos y cuantitativos de la situación epidemiológica y las capacidades básicas. Las unidades territoriales evaluadas comprendían desde zonas básicas de salud hasta CCAA. Resultados: El proceso se extendió del 4 de mayo al 21 de junio y se asoció a planes de refuerzo de las capacidades en las CCAA. La incidencia disminuyó de una mediana inicial de 7,4 por 100.000 en 7 días a 2,5 al final del proceso. La mediana de pruebas PCR aumentó del 53% al 89% de los casos sospechosos, y la capacidad total de 4,5 a 9,8 pruebas semanales por 1.000 habitantes; la positividad disminuyó del 3,5% al 1,8%. La mediana de casos con contactos trazados aumentó del 82% al 100%. Conclusión: La recogida y análisis sistemático de información y el diálogo interterritorial logaron un adecuado control del proceso. La situación epidemiológica mejoró, pero sobre todo, se aumentaron las capacidades, en todo el país y con criterios comunes, cuyo mantenimiento y refuerzo fue clave en olas sucesivas.

[Lessons learnt from COVID-19 surveillance. Urgent need for a new public health surveillance. SESPAS Report 2022]. / Lecciones de la vigilancia de la COVID-19. Necesidad urgente de una nueva vigilancia en salud pública. Informe SESPAS 2022.

In this article we provide the most important epidemiological aspects in the first phases of the pandemic and some preliminary reflections from the Coordinating Centre for Health Alerts and Emergencies, the unit that has coordinated surveillance at the national level. COVID-19 has brought to light the weaknesses in the surveillance system and how difficult it is to manage a health crisis in the absence of a robust public health structure. The commitment of public health professionals during this epidemic has made up for the lack of resources in many occasions, and has evidenced the need to incorporate new professional profiles to surveillance teams. The need to rapidly adapt has achieved an improvement in existing systems and the development of new tools and new systems. These need to turn into structural changes that improve the quality of surveillance, decreasing territorial gaps and ensuring a better and coordinated response to future health crises. It is urgent to incorporate tools for process automation and to grant timely availability of data. To that end, public health and epidemiological surveillance must participate in the process of digital development within the National Health System. Profound changes are needed in public health surveillance, which has to be integrated in all healthcare levels. It is also important to strengthen the capacity for analysis by promoting alliances and joint actions. During this alert, the importance of coordination in public health in a decentralized country has been evident. At international level, it is necessary to review the tools to share data to coordinate an alert from the early stages.

Phlebovirus-associated diseases transmitted by phlebotominae in Spain: Are we at risk?

The genera Phlebovirus transmitted by Diptera belonging to the Psychodidae family are a cause of self-limited febrile syndrome in the Mediterranean basin in summer and autumn. Toscana virus can also cause meningitis and meningoencephalitis. In Spain, Toscana, Granada, Naples, Sicily, Arbia and Arrabida-like viruses have been detected. The almost widespread distribution of Phlebotomus genus vectors, and especially Phlebotomus perniciosus, in which several of these viruses have been detected, makes it very likely that there will be regular human infections in our country, with this risk considered moderate for Toscana virus and low for the other ones, in areas with the highest vector activity. Most of the infections would be undiagnosed, while only Toscana virus would have a greater impact due to the potential severity of the illness.

Characterization of the first autochthonous dengue outbreak in Spain (August-September 2018).

On October 3rd 2018, dengue virus (DENV) infection was confirmed in three family members (symptoms onset between August 18th and 27th) without travel history outside of Spain. They had been together in the Autonomous Communities (AC) of Murcia and Andalusia. By the end of October, a second cluster of two dengue cases (symptoms onset on September 27th and 30th) was confirmed in the AC of Murcia. DENV type 1 sequence was identical to the first cluster, and the epidemiological link was a visit from a case of the first cluster to a fruit-farm neighboring the small village of residence of the second cluster. The entomological investigation found Aedes albopictus activity in this area although all mosquitoes were PCR-negative for DENV. This is the first autochthonous dengue outbreak identified in Spain. This outbreak highlights challenges to timely detect and respond to DENV transmission and opens questions on dengue dynamics in a non-endemic context.

Knowledge and experiences of Chagas disease in Bolivian women living in Spain: a qualitative study.

BACKGROUND: In Europe, Spain has the highest number of people with Chagas disease (CD). Bolivian migrants account for 81% of the reported cases. One of the priorities in controlling the disease is prevention of mother-to-child transmission. Despite under-diagnosis in Spain being estimated at 90%, there are currently few studies that explore the social and cultural dimensions of this disease. OBJECTIVE: The aim of this study was to explore the knowledge and experiences of Bolivian women with CD, in order to generate a useful understanding for the design and implementation of public health initiatives. DESIGN: Qualitative study based on semi-structured interviews, triangular groups, and field notes. PARTICIPANTS: Fourteen Bolivian women with CD living in Madrid. RESULTS: The participants were aware that the disease was transmitted through the vector, that it could be asymptomatic, and that it could also be associated with sudden death by heart failure. They opined that the treatment as such could not cure the disease but only slow it down. There was a sense of indifference along with a lack of understanding of the risk of contracting the disease. Participants who presented with symptoms, or those with relatives suffering from the disease, were concerned about fatalities, cardiac problems, and possible vertical transmission. There was also a fear of being rejected by others. The disease was described as something that affected a large number of people but only showed up in a few cases and that too after many years. There was a widespread assumption that it was better not to know because doing so, allows the disease to take hold. CONCLUSIONS: Disease risk perception was very low in Bolivian women living in Madrid. This factor, together with the fear of being screened, may be contributing to the current rate of under-diagnosis.

La «intervención del tercer día»: análisis de los factores asociados al seguimiento de recomendaciones sobre la prescripción de antibióticos / 'Third day intervention': An analysis of the factors associated with following the recommendations on the prescribing of antibiotics

IINTRODUCCIÓN: Los programas de control de uso de antibióticos suelen incluir intervenciones basadas en recomendaciones no impositivas a los prescriptores. Interesa conocer los factores relacionados con la adherencia a las recomendaciones y su funcionamiento en la práctica real. MÉTODOS: Estudio multicéntrico, controlado y aleatorizado, realizado en 32 unidades de hospitalización. Especialistas en enfermedades infecciosas revisaron, alrededor del tercer día, las prescripciones de antibióticos, estableciendo recomendaciones. Describimos la implantación de la intervención, analizamos los factores asociados al seguimiento de las recomendaciones y el impacto de la intervención. RESULTADOS: Se realizaron 3.192 intervenciones. Las fuentes de información empleadas para la elaboración de las recomendaciones variaron significativamente entre los centros. En el 65% se recomendó alguna modificación del tratamiento: suspender los antibióticos (47%), modificar la vía de administración (26%), cambiar o variar el número de antibióticos (27%) y cambiar la dosis (5%). En el 75% se recomendó simplificar el tratamiento. La adherencia fue del 68%, con variaciones significativas entre los centros, y fue mayor cuando se recomendó ajuste de dosis o cambio de vía, durante el primer periodo del estudio y cuando las recomendaciones se realizaban, además de por escrito, verbalmente. No se pudo constatar impacto en el consumo de antibióticos ni en la incidencia de patógenos resistentes. CONCLUSIONES: Una elevada proporción de tratamientos antibióticos son susceptibles de modificación, generalmente hacia la simplificación. La adherencia a las recomendaciones fue elevada, aunque variable, dependiendo del centro, del tipo de recomendación, del periodo del estudio y de que la recomendación se realizara mediante un comentario verbal además de escrito

INTRODUCTION: Stewardship programs on the use of antibiotics usually include interventions based on non-compulsory recommendations for the prescribers. Factors related to the adherence to expert recommendations, and the implementation of these programmes in daily practice, are of interest. METHODS: A randomized, controlled, multicentre intervention study was performed in 32 hospitalization units. Antibiotic prescriptions were evaluated by an infectious disease specialist on the third day. We describe the implementation of the intervention, the factors associated with adherence to recommendations, and the impact of the intervention. RESULTS: A total of 3,192 interventions were carried out. Information sources used to prepare the recommendations varied significantly between centres. A modification was recommended in 65% of cases: withdrawal (47%), change in administration route (26%), change of drugs or number of antibiotics (27%), and change in dose (5%). Simplification of treatment accounted for 75% of all recommendations. Adherence was 68%, with significant differences between hospitals, and higher when the recommendations consisted of a dose adjustment or change of route, during the first intervention period, and also when recommendations were personally commented on, in addition to writing a note in the clinical chart. We did not find any reduction in antibiotic consumption or variation in the incidence of resistant pathogens. CONCLUSIONS: An important proportion of antibiotic prescriptions may be susceptible to improvement, most of them towards simplification. The adherence to the intervention was high, but significant variations at different centres were observed, depending on the type of recommendation, and the study period. Those recommendations that were personally commented on were more followed more than those only written

Actitudes y prácticas de los médicos de atención primaria ante el diagnósticode la infección por virus de la inmunodeficiencia humana / Primary care doctors attitudes and practices in the diagnosis of HIV infection

Objetivo: Explorar las actitudes y prácticas de los médicos del primer nivel asistencial del Servicio Madrileño de Salud respecto al diagnóstico de la infección por VIH según los protocolos actuales y el grado de aceptación de la introducción de el diagnóstico de la infección VIH de forma simplificada (sin un documento aparte de consentimiento informado ni el interrogatorio acerca de las prácticas de riesgo).Material y métodos Estudio observacional descriptivo transversal realizado en atención primaria de salud de la Comunidad Autónoma de Madrid. La recogida de datos se hizo mediante encuestas telefónicas durante 2009.ResultadosSe consultó a 210 médicos. El 21% ya realizaba el diagnóstico de la infección VIH de forma simplificada y el 28,6% manifestó una actitud favorable hacia las nuevas recomendaciones. El 71,4% no pedía consentimiento informado por escrito aparte y un 42% no manifestó dificultades de comunicación. Una gran mayoría opinó que la excepcionalidad en el manejo del diagnóstico de la infección por VIH, comparándola con otras infecciones de similar forma de transmisión, podría contribuir a mantener el estigma. Para un 75,2% la falta de tiempo en la consulta no representaba un problema y un 97,1% tenía la autopercepción de ser un agente esencial en el diagnóstico de la infección por el VIH. Conclusiones La simplificación del diagnóstico de VIH es aceptable para un porcentaje elevado de los encuestados y uno de cada cinco médicos ya lo está realizando en las consultas de atención primaria (AU)

Objective: To explore the attitudes and practices of Primary Health Care professionals in the diagnosis of HIV infection according to current protocols and the degree of acceptance of simplified HIV testing(without a separate written consent and without asking about risk practices).Material and methods: An observational cross-sectional descriptive study conducted in Primary Care Centres of the Madrid Public Health Service. Data were collected by telephone surveys during 2009.Results: A total of 210 doctors were interviewed.

Tuberculosis complicating hepatitis C treatment in HIV-infected patients.

Tuberculosis characteristics and incidence were assessed among patients with concurrent human immunodeficiency virus infection and chronic hepatitis C virus infection who were receiving interferon-based therapy at 3 hospitals in Spain. Four of 570 patients (0.7 cases per 100 person-years; 95% confidence interval, 0.19-1.78 cases per 100 person-years) received a diagnosis of tuberculosis; all of them presented with a decrease in CD4+ cell count before diagnosis, and 3 of them received a delayed diagnosis. After tuberculosis treatment, all patients were cured.

Delayed diagnosis of HIV infection in a multicenter cohort: prevalence, risk factors, response to HAART and impact on mortality.

To study the prevalence of Delayed HIV Diagnosis (DHD) and its associated risk factors, to evaluate the effect of DHD on virological and immunological responses to HAART and to estimate the impact of DHD on all-causes mortality. Prospective cohort of 2, 564 HIV-positive HAART-naïve subjects attending 19 hospitals in Spain, 2004-2006. Estimations were made by logistic regression and survival analyses by Cox regression models. Prevalence of DHD was 37.3% (35.0-39.6). DHD was related to low educational level (OR:1.31, 95% CI:1.0-1.7). Compared to men who have sex with men (MSM), DHD was more frequent in heterosexuals (OR:1.9 95% CI:1.5-2.5) and injection drug users (IDUs) (OR:2.0 95% CI:1.5-2.8). An interaction between age and sex was found. Although risk of having DHD did not increase after age 30 in women, it increased linearly with age in men. No differences in virological (OR 1.2 95% CI: 0.8-1.8) and CD4 T cell (OR 1.1 95% CI: 0.7-1.8) responses to HAART were seen. The adjusted hazard ratio for death in patients with DHD was 5.2, (95% CI: 1.9-14.5). DHD is very common, especially in older men, heterosexuals and IDUs. Although we did not find differences in virological and immunological responses to HAART, we did observe higher mortality in people with DHD. Increased efforts to early diagnose HIV infection are urgently needed.
