[An outbreak of Burkholderia cepacia bacteremia in a hemodialysis unit, Cadiz, 2014]. / Brote de bacteriemia por Burkholderia cepacia en una unidad de hemodiálisis de Cádiz, 2014.

INTRODUCTION: In January 2014 a possible outbreak of Burkholderia cepacia bacteremia occurred in a hemodialysis center situated in La Linea de la Concepción (Cadiz). An investigation was begun to confirm the outbreak, identify the source, and implement control measures. METHODS: A descriptive analysis was performed to describe the characteristics of the patients affected with Burkholderia cepacia bacteremia from November 2013 to February 2014. Environmental samples were taken. A molecular typing study was performed using pulsed field gel electrophoresis (SpeI PFGE) and MLST analysis in order to determine the genetic similarity between the isolates. RESULTS: The bacterium was isolated from blood cultures of 7 patients during the study period. Three of the samples (2 of which were also cases) were endoluminal fluid from catheter locks, and 4 chlorhexidine bottle samples. The patients were coincident in 2 of the 6 work shifts. The mean age of the cases was 67 years of whom 57% were women. Human samples and an environmental sample was analyzed and found to be genetically identical (ST653 clone). CONCLUSIONS: The analysis confirmed the outbreak of Burkholderia cepacia, with 7 cases among the patients of the hemodialysis center. The outbreak was due to the same strain, probably a common source and secondary transmission from person to person.

Immunization Strategies Targeting Newly Arrived Migrants in Non-EU Countries of the Mediterranean Basin and Black Sea.

Background: The World Health Organization recommends that host countries ensure appropriate vaccinations to refugees, asylum seekers and migrants. However, information on vaccination strategies targeting migrants in host countries is limited. Methods: In 2015-2016 we carried out a survey among national experts from governmental bodies of 15 non-EU countries of the Mediterranean and Black Sea in order to document and share national vaccination strategies targeting newly arrived migrants. Results: Four countries reported having regulations/procedures supporting the immunization of migrants at national level, one at sub-national level and three only targeting specific population groups. Eight countries offer migrant children all the vaccinations included in their national immunization schedule; three provide only selected vaccinations, mainly measles and polio vaccines. Ten and eight countries also offer selected vaccinations to adolescents and adults respectively. Eight countries provide vaccinations at the community level; seven give priority vaccines in holding centres or at entry sites. Data on administered vaccines are recorded in immunization registries in nine countries. Conclusions: Although differing among countries, indications for immunizing migrants are in place in most of them. However, we cannot infer from our findings whether those strategies are currently functioning and whether barriers to their implementation are being faced. Further studies focusing on these aspects are needed to develop concrete and targeted recommendations for action. Since migrants are moving across countries, development of on-line registries and cooperation between countries could allow keeping track of administered vaccines in order to appropriately plan immunization series and avoid unnecessary vaccinations.

Geographical and Temporal Variations in Female Breast Cancer Mortality in the Municipalities of Andalusia (Southern Spain).

The last published figures have shown geographical variations in mortality with respect to female breast cancer in European countries. However, national health policies need a dynamic image of the geographical variations within the country. The aim of this paper was to describe the spatial distribution of age-specific mortality rates from female breast cancer in the municipalities of Andalusia (southern Spain) and to analyze its evolution over time from 1981 to 2012. An ecological study was devised. Two spatio-temporal hierarchical Bayesian models were estimated. One of these was used to estimate the age-specific mortality rate for each municipality, together with its time trends, and the other was used to estimate the age-specific rate ratio compared with Spain as a whole. The results showed that 98% of the municipalities exhibited a decreasing or a flat mortality trend for all the age groups. In 2012, the geographical variability of the age-specific mortality rates was small, especially for population groups below 65. In addition, more than 96.6% of the municipalities showed an age-specific mortality rate similar to the corresponding rate for Spain, and there were no identified significant clusters. This information will contribute towards a reflection on the past, present and future of breast cancer outcomes in Andalusia.

[Outbreaks of Measles in Andalusia, Spain, during the Period 2010-2015]. / Brotes epidémicos de sarampión en Andalucía durante el período 2010-2015.

The Andalusian Surveillance Epidemiological System (SVEA) controls and investigates any notification of measles or any other communicable disease. The aim of this article is to describe the epidemiological characteristics of measles outbreaks occurred in Andalusia in the last five years (2010-2015) and their control measures. In this period three outbreaks were reported: the first one started in Granada in 2010 in a community of objectors to vaccination. Control measures of measles protocol of SVEA were adopted (case isolation, identification and contacts immunization), including judicial measures among the group who refused the vaccination. The second outbreak started in Seville in 2011 in an "area in need of social transformation" and it spread throughout the region. The routine vaccination coverage review was introduced within the surveillance system after those outbreaks, identifying the most vulnerable people. During the first six months of 2015, a small outbreak, of 15 cases, occurred in Granada. The outbreak was controlled mainly due to the early intervention, the health measures adopted in the schools and health centres involved and the high vaccination coverage achieved in the population.
