RESUMEN

BackgroundBy mid-September 2023, several event notifications related to cryptosporidiosis had been identified from different regions in Spain. Therefore, a request for urgent notification of cryptosporidiosis cases to the National Surveillance Network was launched.AimWe aimed at assessing the extent of the increase in cases, the epidemiological characteristics and the transmission modes and compared to previous years.MethodsWe analysed data on case notifications, outbreak reports and genotypes focusing on June-October 2023 and compared the results to 2016-2022.ResultsIn 2023, 4,061 cryptosporidiosis cases were notified in Spain, which is an increase compared to 2016-2022. The cumulative incidence was 8.3 cases per 100,000 inhabitants in 2023, sixfold higher than the median of 1.4 cases per 100,000 inhabitants 2016-2022. Almost 80% of the cases were notified between June and October. The largest outbreaks were related to contaminated drinking water or swimming pools. Cryptosporidium hominis was the most common species in the characterised samples (115/122), and the C. hominis IfA12G1R5 subtype, previously unusual in Spain, was detected from 76 (62.3%) of the 122 characterised samples.ConclusionsA substantial increase in cryptosporidiosis cases was observed in 2023. Strengthening surveillance of Cryptosporidium is essential for prevention of cases, to better understand trends and subtypes circulating and the impact of adverse meteorological events.

RESUMEN

Following the report of a non-travel-associated cluster of monkeypox cases by the United Kingdom in May 2022, 41 countries across the WHO European Region have reported 21,098 cases and two deaths by 23 August 2022. Nowcasting suggests a plateauing in case notifications. Most cases (97%) are MSM, with atypical rash-illness presentation. Spread is mainly through close contact during sexual activities. Few cases are reported among women and children. Targeted interventions of at-risk groups are needed to stop further transmission.

RESUMEN

Multidrug-resistant Gram-negative bacteria (MDR-GNB) are microorganisms that have acquired resistance to extended-spectrum antibacterials and constitute an emerging threat to public health. Although carriers are an important source of transmission in healthcare settings, data about risk factors for MDR-GNB carriage are limited. Therefore, we aimed to identify risk factors for MDR-GNB carriage upon intensive care unit (ICU) admission and to optimise screening strategies. We conducted a case-control study. Admissions of adult patients to the ICU of a 1000-bed hospital during a year were included. We collected sociodemographic, clinical and microbiological data and performed a multivariate logistic regression model. A total of 1342 patients resulted in 1476 episodes of ICU admission, 91 (6.2%) of whom harboured MDR-GNB (38.5% women; median age 63.9 years). The most frequently isolated pathogens were Escherichia coli (57%) and Klebsiella pneumoniae (16%). The most frequent resistance mechanism was production of extended-spectrum beta lactamases. MDR-GNB carriage was associated to liver cirrhosis (OR 6.54, 95% CI 2.17-19.17), previous MDR-GNB carriage (OR 5.34, 1.55-16.60), digestive surgery (OR 2.83, 1.29-5.89) and length of hospital stay (OR 1.01 per day, 1.00-1.03). Several risk factors for MDR-GNB carriage upon admission to a high-risk setting were identified; the main comorbidity was liver cirrhosis.

RESUMEN

Over 79,000 confirmed cases of mpox were notified worldwide between May and November 2022, most of them in men who have sex with men. Cases in women, for whom mpox might pose different risks, are rare, and Spain has reported more than one third of those in Europe. Using surveillance data, our study found similar time trends, but differences in delay of diagnosis, sexual transmission and signs and symptoms between men and women.

RESUMEN

The monthly retrospective search for unreported acute flaccid paralysis (AFP) cases conducted as a complementary component of the Spanish AFP surveillance system identified a case of AFP in a child admitted in Spain from Senegal during August 2021. Vaccine-derived poliovirus 2 was identified in the stool in September 2021. We present public health implications and response undertaken within the framework of the National Action Plan for Polio Eradication and the Public Health Emergency of International Concern.

RESUMEN

COVID-19 outbreak surveillance in Spain was established with the main objective of characterizing outbreaks and the settings in which they occurred, in order to identify those population groups at highest risk to support them with the implementation of preventive and control measures. Between June 2020 and June 2021, 55,824 outbreaks were reported, with 414,882 cases in all settings. About 12.5% were reported in an occupational setting and within this, most of them were identified in the industry and building sectors. The outbreaks that had a greater impact were those that took place both in agriculture and in the meat industry, where there is a higher risk of exposure due to living and working conditions. Outbreaks in the catering and home care sectors were also frequent. Since the beginning, there was coordination between all stakeholders involved in the management of the pandemic, in order to implement prevention and control measures, as well as social protection measures. In addition, special actions were implemented in the most vulnerable sectors. Despite the work carried out, the presence of outbreaks in these sectors continues, although they are smaller than the previous pandemic phase. Due to this, there is needed to continue strengthening the inter-sectoral coordination structures and mechanisms to ensure the implementation of those measures that contribute to the containment of the pandemic.


La vigilancia de brotes COVID-19 en España se estableció con el objetivo de caracterizar los brotes y los ámbitos en los que ocurrían, con el propósito de identificar aquellos grupos de población con mayor riesgo para apoyar la toma de medidas de prevención y control. Entre junio de 2020 y junio de 2021 se comunicaron 55.824 brotes con 414.882 casos en todos los ámbitos. Alrededor del 12,5% de brotes y casos asociados fueron comunicados en el ámbito laboral y dentro de éste, la mayoría se identificó en los sectores de la industria y construcción, si bien, entre los brotes que han tenido un mayor impacto se encuentran aquellos producidos en el sector agrícola y en la industria de la carne, donde existe un mayor riesgo de exposición debido a las condiciones de vida y trabajo. También destacaron los brotes en el sector de la restauración y hostelería, y cuidados a domicilio. Desde el inicio hubo una coordinación entre las administraciones implicadas en la gestión de la pandemia para poner en marcha las medidas de prevención y control, así como las de protección social. Además, se llevaron a cabo medidas especiales en sectores de mayor vulnerabilidad. A pesar del trabajo realizado, los brotes en estos sectores continúan ocurriendo, si bien son de menor tamaño, por lo que se deben continuar fortaleciendo las estructuras y mecanismos de coordinación intersectoriales para la aplicación de las medidas que contribuyen además de la contención de la pandemia, a mantener activo el tejido productivo.

RESUMEN

Global climate change is predicted to alter precipitation and temperature patterns across the world, affecting a range of infectious diseases and particularly foodborne infections such as Campylobacter. In this study, we used national surveillance data to analyse the relationship between climate and campylobacteriosis in Denmark, Finland, Norway and Sweden and estimate the impact of climate changes on future disease patterns. We show that Campylobacter incidences are linked to increases in temperature and especially precipitation in the week before illness, suggesting a non-food transmission route. These four countries may experience a doubling of Campylobacter cases by the end of the 2080s, corresponding to around 6,000 excess cases per year caused only by climate changes. Considering the strong worldwide burden of campylobacteriosis, it is important to assess local and regional impacts of climate change in order to initiate timely public health management and adaptation strategies.

RESUMEN

INTRODUCCIÓN: Bexsero® (4CMenB), vacuna contra el meningococo B, fue autorizada en Europa en 2013. En España, a pesar de que el meningococo B es la principal causa de enfermedad meningocócica invasiva (EMI), Bexsero® está recomendada y financiada para pacientes con alto riesgo de EMI pero no de forma sistemática en el calendario vacunal del SNS. OBJETIVO: Evaluar el coste-utilidad, el impacto epidemiológico y los costes totales de la introducción de 4CMenB para una política vacunal informada en España. MÉTODO: Se adaptó para España un análisis de coste-utilidad, árbol de decisión probabilístico. Una cohorte de recién nacidos en 2015 fue modelizada con dos posologías mediante dos estrategias: vacunación sistemática con 4CMenB o no vacunación. Los costes se midieron desde la perspectiva del pagador y los beneficios se calcularon en años de vida ajustados por calidad (AVAC). Se realizó un análisis de Monte Carlo y se consideraron 32 escenarios para valorar la robustez y la incertidumbre de los resultados. RESULTADOS: Con la pauta 3+1, la vacunación sistemática previno el 54% de los casos y de las muertes, y se estimó una razón de coste-utilidad incremental (RCUI) de 351.389 €/AVAC (intervalo de confianza del 95% [IC95%]: 265.193-538.428). La pauta 2+1 previno el 50% de los casos y de las muertes, con una RCUI de 278.556 €/AVAC (IC95%: 210.285-430.122). CONCLUSIONES: Dada la incidencia actual de enfermedad meningocócica invasiva en España y la información disponible sobre 4CMenB, nuestro modelo indica que la vacunación sistemática no es coste-efectiva con el actual precio. Solo con un precio de 1,45 € para la pauta 3+1 o de 3,37 € para la pauta 2+1 podría ser recomendada basándose en su eficiencia


INTRODUCTION: Bexsero® (4CMenB), meningococcal B vaccine, was licensed in Europe in 2013. In Spain, despite MenB being the most frequent cause of invasive meningococcal disease (IMD), Bexsero® is recommended and financed for patients at increased risk of IMD but is not financed by the NHS in the routine vaccination schedule. OBJECTIVE: to evaluate the cost-utility, epidemiological impact, and total costs of the introduction of 4CMenB into the vaccination schedule to help inform vaccine policy in Spain. METHOD: We adapted a cost-utility analysis, a probabilistic decision-tree, to Spain. A cohort of new-born infants in 2015 was modelled with two dosages, using two different strategies: routine vaccination schedule with 4CMenB and non-vaccination. Costs were measured from a payer perspective and benefits were calculated in quality-adjusted life years (QALYs). A Monte Carlo analysis and 32 scenarios were performed to assess the robustness and the uncertainty of our results. RESULTS: With the 3+1 dosage, routine vaccination prevented 54% of cases and deaths and an incremental cost-utility ratio (ICUR) of 351.389 €/QALY (95% confidence interval [95%CI]: 265,193-538,428) was estimated. The 2+1 dosage prevented 50% of cases and deaths, with an ICUR of 278.556 €/QALY (95%CI: 210,285-430,122). CONCLUSIONS: Given the current incidence of invasive meningococcal disease in Spain and the information available from 4CMenB, our model shows that routine vaccination is not cost-effective at the current price. Only with a vaccine price of 1.45 € for the 3+1 schedule or 3.37 € for the 2+1 schedule could it be recommended based on efficiency criteria

RESUMEN

Aims: This study aimed to describe the demographic and geographic patterns of campylobacteriosis in Denmark, Finland, Norway and Sweden during 2000-2015. Methods: All Campylobacter infections notified to national authorities in the four countries during the study period were included. Background data for each notification consisted of patient age, sex, geographical location, presumed origin of infection and date of sample taken or date of sample received in the laboratory. These data were analysed in order to investigate annual trends, age group and sex patterns, as well as variations in the geographical and seasonal distribution of infections. Results: During the study period, a total of 164,001 Campylobacter infections, excluding travel-related cases, were registered, representing a mean annual incidence of 42.3 cases/100,000 population (ranging from 28.5 in Norway to 60.4 in Denmark). The incidence increased significantly from 2004 onwards in all countries, apart from Denmark. Males had higher infection rates in general. The highest incidences were observed in 0-4 year olds and those aged 20-29 years, apart from in Finland where there was no peak of infections in children aged 0-4 years. Seasonality of disease was distinct in all four countries, showing peaks of infection between July and August. In Sweden and Norway, incidences of campylobacteriosis were significantly higher in municipalities with high degrees of coastline or inland water. Conclusions: Campylobacter in the Nordic countries mostly follows known patterns with respect to demography and seasonality. Our study demonstrates new insights concerning geographical patterns of disease, highlighting possible future vulnerable population groups and locations.

RESUMEN

Despite concerns about infection risks of floating tanks, outbreaks have rarely been reported. In May 2017, an outbreak of skin rash occurred among visitors of a floating tank open for the public in Norway. We assessed the extent and cause of the outbreak and the risk factors for infection in a retrospective cohort study among the visitors of the floating tank using a standardized web-based questionnaire. An environmental investigation was conducted including microbiological analysis of the floating tank water. Of the 46 respondents to the questionnaire (61 distributed), 22 reported symptoms, most commonly palmar and plantar rash, swollen lymph nodes, ear canal pain and itching. None of the investigated risk factors, such as sex, age, duration of bathing or use of the shower after bathing, were significantly associated with illness. The results of the environmental investigation indicated that the water was heavily contaminated by P. aeruginosa and heterotrophic bacteria. The outbreak investigation highlights the need to ensure adequate hygienic operation of floating tanks. Awareness about responsibilities should be raised among the operators of floating tanks and relevant operational parameters for floating tanks should be made available for local health authorities.

RESUMEN

We conducted a matched case-control study to examine the association between heavy precipitation events and waterborne outbreaks (WBOs) by linking epidemiological registries and meteorological data between 1992 and 2012 in four Nordic countries. Heavy precipitation events were defined by above average (exceedance) daily rainfall during the preceding weeks using local references. We performed conditional logistic regression using the four previous years as the controls. Among WBOs with known onset date (n = 89), exceedance rainfall on two or more days was associated with occurrence of outbreak, OR = 3.06 (95% CI 1.38-6.78), compared to zero exceedance days. Stratified analyses revealed a significant association with single household water supplies, ground water as source and for outbreaks occurring during spring and summer. These findings were reproduced in analyses including all WBOs with known outbreak month (n = 186). The vulnerability of single households to WBOs associated with heavy precipitation events should be communicated to homeowners and implemented into future policy planning to reduce the risk of waterborne illness.

RESUMEN

In May 2014, a cluster of Yersinia enterocolitica (YE) O9 infections was reported from a military base in northern Norway. Concurrently, an increase in YE infections in civilians was observed in the Norwegian Surveillance System for Communicable Diseases. We investigated to ascertain the extent of the outbreak and identify the source in order to implement control measures. A case was defined as a person with laboratory-confirmed YE O9 infection with the outbreak multilocus variable-number tandem repeat analysis (MLVA)-profile (5-6-9-8-9-9). We conducted a case-control study in the military setting and calculated odds ratios (OR) using logistic regression. Traceback investigations were conducted to identify common suppliers and products in commercial kitchens frequented by cases. By 28 May, we identified 133 cases, of which 117 were linked to four military bases and 16 were civilians from geographically dispersed counties. Among foods consumed by cases, multivariable analysis pointed to mixed salad as a potential source of illness (OR 10.26; 95% confidence interval (CI): 0.85-123.57). The four military bases and cafeterias visited by 14/16 civilian cases received iceberg lettuce or radicchio rosso from the same supplier. Secondary transmission cannot be eliminated as a source of infection in the military camps. The most likely source of the outbreak was salad mix containing imported radicchio rosso, due to its long shelf life. This outbreak is a reminder that fresh produce should not be discounted as a vehicle in prolonged outbreaks and that improvements are still required in the production and processing of fresh salad products.

RESUMEN

BACKGROUND: We describe the status of waterborne outbreaks notified in Norway and discuss this in the context of outbreaks recorded in previous years, to gain a better understanding of their development in Norway in recent years. MATERIAL AND METHOD: We have collected information on all outbreaks notified to the Norwegian Institute of Public Health via the surveillance system for communicable diseases in the ten-year period from 2003-2012 for which drinking water was given as the suspected cause. RESULTS: Altogether 28 waterborne outbreaks with a total of 8,060 persons reported as ill were notified in the period. The majority of outbreaks resulted in fewer than 100 cases of illness. There were two outbreaks with more than 1,000 cases of illness: an oubreak of campylobacteriosis in Røros and an oubreak of giardiasis in Bergen. In more than half of the outbreaks, water was supplied from public water distribution systems (16/28 outbreaks, 57%). In addition, a large proportion was linked to individual households with their own water supply (12/28 outbreaks, 43%). INTERPRETATION: Most of the outbreaks in the ten-year period were linked to public water distribution systems, while almost half were linked to non-disinfected water supplies to individual households. Although most of the outbreaks were small, two extensive outbreaks were also registered in the period, resulting in more than one thousand cases of illness. This underscores the need for good contingency planning and surveillance, so that suspicion of waterborne outbreaks is rapidly notified to the responsible authorities, and the importance of good protection of water sources, as well as proper maintenance of water treatment plants and distribution systems.

RESUMEN

BACKGROUND: Hospital-acquired pneumonia (HP) is the most common infection in adult intensive care units (ICUs). To develop effective strategies to prevent it, we identified factors that independently increased the risk of contracting HP while admitted at an ICU. METHODS: We performed a prospective cohort study during 4 years in which we included all patients who had been admitted for at least 24 h to the ICU at a university reference hospital in Spain. We conducted a multivariable Cox regression analysis to obtain adjusted hazard ratios (HR). The dependent variable for patients with HP was duration of ICU stay prior to the onset of HP. For those without HP, the dependent variable was duration of stay between admission and discharge from the ICU. The independent variables were intrinsic characteristics of the patients already present at admission to the ICU and diagnostic or therapeutic procedures performed during admission. RESULTS: We studied 4427 patients, of which 233 (5.3%) developed HP while admitted to the ICU. The strongest independent risk factors associated with the occurrence of HP were mechanical ventilation (HR = 8.2; 95% CI = 3.6-18.9) and the use of a nasogastric tube (HR = 2.3; 95% CI = 1.6-3.3). The intrinsic risk factors that were part of the model were the presence of decreased level of consciousness upon admission (HR = 2.0; 95% CI = 1.5-2.7) and the APACHE II index (HR = 1.018; 95% CI = 1.002-1.035). CONCLUSIONS: Although severity of illness upon admission (APACHE II index) and decreased level of consciousness were relevant predisposing factors to contract HP in the ICU, the strongest association corresponded to extrinsic factors such as mechanical ventilation and use of a nasogastric tube. The fact that these are therapeutic interventions facilitates developing prevention and control measures that can contribute to reduce the risk for HP.

RESUMEN

Протокол по проблемам воды и здоровья к Конвенции по охране и использованию трансграничных водотоков и международных озер 1992 г. направлен на защиту здоровья и благополучия людей путем связи устойчивого управления водными ресурсами с деятельностью по предотвращению, ограничению и сокращению степени распространения заболеваний, связанных с водой. Предотвращение заболеваний, связанных с водой, и сокращение их числа является одним из приоритетов программы работы в рамках Протокола на 2014-2016 гг. В результате обзора имеющихся фактических данных было обнаружено существенное занижение сведений и недооценка реального масштаба распространенности заболеваний, связанных с водой, в Общеевропейском регионе, что указывает на необходимость укрепить национальные возможности в области надзора за этими заболеваниями. К наиболее часто регистрируемым желудочно-кишечным инфекционным заболеваниям, которые могут быть связаны с водой, относятся кампилобациллярный энтерит, лямблиоз, гепатит А и шигеллез. Ограниченные опубликованные данные указывают на то, что примерно 18% расследованных вспышек заболеваний в Европейском регионе ВОЗ могут быть связаны с этим источником. Делаются определенные успехи по установке конкретных целевых показателей по предотвращению и сокращению случаев заболеваний, связанных с водой, и укреплению систем надзора и раннего предупреждения в соответствии с основными положениями Протокола.

RESUMEN

The Protocol on Water and Health to the 1992 Convention on the Protection and Use of Transboundary Watercourses and International Lakes aims at protecting human health and well-being through sustainable water management and the prevention, control and reduction of water-related diseases. Prevention and reduction of water-related diseases is a priority area under the Protocol’s programme of work 2014–2016. A review of the available evidence reveals significant underreporting and underestimation of the true extent of water-related diseases in the pan-European region, indicating a need to strengthen national capacities for surveillance of these diseases. Campylobacteriosis, giardiasis, hepatitis A and shigellosis are the most commonly reported gastrointestinal infectious diseases that could be attributed to water. According to limited published data, about 18% of investigated outbreaks in the WHO European Region may be associated with this source. There has been progress in setting specific targets for prevention and reduction of water-related diseases and for strengthening surveillance and early-warning systems in accordance with the core provisions of the Protocol.

RESUMEN

In March 2014, after an increase of notifications of domestically acquired hepatitis A virus infections, an outbreak investigation was launched in Norway. Sequenced-based typing results showed that these cases were associated with a strain that was identical to one causing an ongoing multinational outbreak in Europe linked to frozen mixed berries. Thirty-three confirmed cases with the outbreak strain were notified in Norway from November 2013 to June 2014. Epidemiological evidence and trace-back investigations linked the outbreak to the consumption of a berry mix cake. Identification of the hepatitis A virus outbreak strain in berries from one of the implicated cakes confirmed the cake to be the source. Subsequently, a cluster in Germany linked to the cake was also identified.
