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.

Monkeypox outbreak predominantly affecting men who have sex with men, Madrid, Spain, 26 April to 16 June 2022.

Up to 22 June 2022, 508 confirmed cases of monkeypox (MPX) have been reported in the Madrid region of Spain, 99% are men (n = 503) with a median age of 35 years (range: 18-67). In this ongoing outbreak, 427 cases (84.1%) reported condomless sex or sex with multiple partners within the 21 days before onset of symptoms, who were predominantly men who have sex with men (MSM) (n = 397; 93%). Both the location of the rash, mainly in the anogenital and perineal area, as well as the presence of inguinal lymphadenopathy suggest that close physical contact during sexual activity played a key role in transmission. Several cases reported being at a sauna in the city of Madrid (n = 34) or a mass event held on the Spanish island of Gran Canaria (n = 27), activities which may represent a conducive environment for MPX virus spread, with many private parties also playing an important role. Because of the rapid implementation of MPX surveillance in Madrid, one of the largest outbreaks reported outside Africa was identified. To minimise transmission, we continue to actively work with LGBTIQ+ groups and associations, with the aim of raising awareness among people at risk and encouraging them to adopt preventive measures.

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.

Dealing with Ebola virus disease in Spain: epidemiological inquiries received by the Department of Public Health Alerts, April to December 2014.

We describe the inquiries regarding Ebola virus disease (EVD) received by the Department of Public Health Alerts of the Community of Madrid between April and December 2014. A total of 242 inquiries were received. Consultations were initiated most frequently by hospital clinicians (59 inquiries, 24%), private citizens (57 inquiries, 24%) and primary care physicians (53 inquiries, 22%). The most frequent topic of inquiry was possible EVD in a patient (215 inquiries, 89%). Among these, 31 persons (14%) presented both EVD-compatible symptoms and epidemiological risk factors, and 11 persons (5%) fulfilled the criteria for a person under investigation. Recent travel abroad was reported in 96 persons (45%), but only 32 (15%) had travelled to an EVD-affected area. Two high-risk and one low-risk contact were identified through these inquiries. Low specificity of the EVD symptoms led to many difficulties in protocol application. Ineffective communication with healthcare professionals and unfamiliarity with the EVD protocols caused many case classification errors. A rapid consultation service by telephone is essential for providing qualified advice during emergencies. Our experience may help other countries dimension their activities and resources for managing similar exceptional outbreaks in the future.

[Community transmission of pandemic influenza (H1N1) 2009 from School Outbreaks in the Madrid region, Spain: May-June 2009]. / Transmisión comunitaria de gripe pandémica (H1N1) 2009 a partir de brotes en centros escolares de la Comunidad de Madrid: Mayo-junio de 2009.

BACKGROUND: The first pandemic influenza (H1N1) 2009 confirmed case acquired in the Madrid Region was diagnosed in May 20th. This was the index case of the first outbreak in a school in the Madrid Region (MR). The aim of this paper is to describe school outbreaks that took place during the spring in 2009, the control measures implemented and the beginning of the community transmission of this virus in the Region. METHODS: Descriptive observational study of school outbreaks due to pandemic (H1N1) 2009 virus reported between May 20th and June 27th, and total investigated cases in this period. It was used the definition of cluster of influenza cases adopted by National Authority (three or more cases). Clinical, epidemiological and microbiological data of cases were analyzed. RESULTS: There were identified 1.349 cases of pandemic (H1N1) 2009. They were associated with 77 school centres with three or more reported cases, 47,4% of total cases in this period (n = 2.844). 36 outbreaks were detected in Leganés (more than one third of all schools in the municipality), generating the highest cumulative incidence rates in the Basic Health Zone. There were differences by symptoms according to age. During this period, 949 samples were analyzed and 555 (58.5%) tested positive. CONCLUSIONS: The transmission of pandemic (H1N1) 2009 virus in the MR occurred steadily during the spring of 2009 due to schools outbreaks, meaning the onset of community transmission in Spain.

[Daily Surveillance of Pandemic Influenza (H1N1) 2009 by primary care electronic clinical records in the Madrid region]. / Vigilancia diaria de la gripe pandémica (H1N1) 2009 mediante registros de la historia clínica electrónica de atención primaria en la Comunidad de Madrid.

BACKGROUND: Pandemic influenza (H1N1) 2009 led to implementation in the Madrid Region of new strategies of epidemiology surveillance in order to give response to the need of immediacy and exhaustiveness. METHODS: Descriptive cross-sectional study between May 1th 2009 and May 22th 2010. All disease episodes registered and reported as influenza disease were collected every day from electronic clinical records in primary care of Madrid Regional Public Health System. Data were analyzed by date, age, sex and health zoning, disaggregating into health professionals. RESULTS: 165.492 influenza episodes were registered (53,8% in women). The main number of cases was in the 25-49 years group (70.691), and the 5-14 years group reached the maximum weekly incidence rate (1.618,65/100.000 in the week 43). The highest weekly total incidence rate was 458,47/100.000 (week 44). Pediatricians reached the maximum of cases visited and of cumulated rates (12 pediatricians visited more than 20% of their total assigned population). CONCLUSIONS: Surveillance of pandemic influenza (H1N1) 2009 by automatic daily data collection from electronic clinical records in primary care has meant a specially useful information source for monitoring the development of pandemic influenza and for the strategic decision making.
