National immunization strategies targeting migrants in six European countries.

Over the last three years an unprecedented flow of migrants arrived in Europe. There is evidence that vaccine preventable diseases have caused outbreaks in migrant holding centres. These outbreaks can be favored by a combination of factors including low immunization coverage, bad conditions that migrants face during their exhausting journey and overcrowding within holding facilities. In 2017, we conducted an online survey in Croatia, Greece, Italy, Malta, Portugal and Slovenia to explore the national immunization strategies targeting irregular migrants, refugees and asylum seekers. All countries stated that a national regulation supporting vaccination offer to migrants is available. Croatia, Italy, Portugal and Slovenia offer to migrant children and adolescents all vaccinations included in the National Immunization Plan; Greece and Malta offer only certain vaccinations, including those against diphtheria-tetanus-pertussis, poliomyelitis and measles-mumps-rubella. Croatia, Italy, Malta and Portugal also extend the vaccination offer to adults. All countries deliver vaccinations in holding centres and/or community health services, no one delivers vaccinations at entry site. Operating procedures that guarantee the migrants' access to vaccination at the community level are available only in Portugal. Data on administered vaccines is available at the national level in four countries: individual data in Malta and Croatia, aggregated data in Greece and Portugal. Data on vaccination uptake among migrants is available at national level only in Malta. Concluding, although diversified, strategies for migrant vaccination are in place in all the surveyed countries and generally in line with WHO and ECDC indications. Development of procedures to keep track of migrants' immunization data across countries, development of strategies to facilitate and monitor migrants' access to vaccinations at the community level and collection of data on vaccination uptake among migrants should be promoted to meet existing gaps.

Analysis of 22 Years of Surveillance for Prion Diseases in Slovenia, 1996 to 2017.

INTRODUCTION: The objective was to present the results of surveillance of prion diseases in Slovenia that was established in 1996 and then to assess the interdisciplinary approach according to the algorithm of case management and reporting data to the National Register at the National Institute of Public Health. METHODS: A descriptive study of Creutzfeldt-Jakob disease (CJD) recorded in the period from 1996 to 2017 was carried out. RESULTS: A total of 123 cases of prion disease were notified between 1996 and 2017. Out of these, 68 were recorded and confirmed by autopsy as sporadic CJD with an average incidence rate of 1,5 cases per million population per year. In one case a gene analysis showed mutation E200K in prion protein gene, PRNP. Two cases of the Gerstman-Sträussler Scheinker syndrome and one clinical case of fatal insomnia with new PRNP mutation, N181S, were notified. Diagnostic value of protein 14-3-3 analysis in the liquor reached 82% sensitivity and 71% specificity. 25 cases of notified clinically possible/probable CJD were disproved after autopsy. In eleven notified possible CJD cases the autopsy had not been performed. Variant CJD has not yet been proven in Slovenia. CONCLUSION: Incidence rates were comparable with other European countries. Completeness of reporting and proper management of CJD cases according to the algorithm of reporting, management and case confirmation would need some improvement. A well-functioning surveillance system, including timely notifications, would enable an appropriate epidemiological investigation and an effective response to public health risks, thus the awareness of prion diseases should not decline.

High Incidence of Sporadic Creutzfeldt-Jakob Disease in Slovenia in 2015: A Case Series.

BACKGROUND: Creutzfeldt-Jakob disease (CJD) is a rare fatal neurodegenerative disorder presenting with rapid cognitive decline and additional signs. The clinical characteristics of an increasing number of sporadic CJD (sCJD) patients admitted to the Ljubljana University Medical Centre are presented as well as the incidence of sCJD in Slovenia in 2015 compared to previous years. METHODS: We investigated patients presenting with rapidly progressive dementia and at least one additional sign. The diagnosis was made based on clinical diagnostic criteria and an autopsy was performed in all cases. Data on definite sCJD cases in Slovenia since 1999 were obtained and its incidence was calculated. RESULTS: Eight patients with definite sCJD died in 2015 in Slovenia (incidence: 3.89 cases per million). The long-term incidence 1999 was 1.67 per million. CONCLUSIONS: The incidence of sCJD was considerably higher in 2015. It reflects fluctuations in sporadic cases of this rare disease. The rising trend might indicate a previous underestimation and better recognition of the disease.
