Enhancing routine immunization efforts for older adults and frail individuals: Good practices during the SARS-CoV-2 pandemic in Italy.

Infectious diseases pose a significant burden on the general population, particularly older adults who are more susceptible to severe complications. Immunization plays a crucial role in preventing infections and securing a healthier aging, but actual vaccination rates among older adults and frail individuals (OAFs) remains far from recommended targets. This study aims to collect and share good practices implemented in several Italian local health districts during the SARS-CoV-2 pandemic to ease routine immunization for OAFs. A 28-items questionnaire has been developed to collect information on organization aspect of immunization services and local good practices implemented before and during the SARS-CoV-2 pandemic. Twelve Public Health managers representative of 9 Italian Regions were further interviewed between January and March 2021. Despite literature suggests several effective interventions to increase vaccine demand, improve vaccine access, and enhance healthcare providers' performance, our survey highlighted substantial heterogeneity in their implementation at local level. Seven good local practices have been identified and described: mass vaccination centers; vaccination mobile units; drive-through vaccination; co-administration; tailored pathways; cooperation among providers involved in vaccination; digitization. Our survey pointed out valuable strategies for enhancing routine immunization for OAFs. Providers should combine effective interventions adequate to their specific context and share good practices.

Infectious risk profile and strategies for prevention and control of outbreaks in refugee, asylum seekers and migrant populations in EU/EEA countries: a systematic narrative review of evidences.

Introduction: The recent surge in migration to and within the European Union and European Economic Area has brought the development of migration policy, including health policy, to the forefront of regional priorities. While migrants, in general, do not pose a health threat to the host population, specific subgroups of migrants, including refugees, asylum seekers, and irregular migrants, are particularly vulnerable to infectious diseases. To support public health policies in this area, the Emergency Preparedness and Management' working group of the Italian Society of Hygiene, Preventive Medicine and Public Health has conducted a systematic narrative review with the aim to comprehensively analyze the infectious disease risk within the refugee and asylum seeker populations in EU, EEA, and EU-applicant countries. Methods: Forty-two studies were systematically selected from scientific articles in the MEDLINE/PubMed database from January 1, 2008, to June 1, 2023. The infectious risk associated with each infectious disease among refugees and asylum seekers, as well as the strategies to prevent and control outbreaks, was collected from all available studies. Results: The congregate living conditions in refugee camps, transit centers, and temporary housing facilities make this population particularly vulnerable to infectious diseases. As such, implementing stringent hygiene and preventive measures is critical to safeguarding the health of refugees and reducing the risk of outbreaks that may affect both the refugee population and the host communities. Conclusion: Effective vaccination and preventive strategies for migrants, refugees, and asylum seekers are vital for public health and the well-being of these populations. They should be delivered as part of universal health care. By addressing barriers and implementing tailored programs, we can ensure equitable access to vaccines and protect the health of these vulnerable individuals.

Epidemiology of listeriosis in a region in central Italy from 2010 to 2019: Estimating the real incidence and space-time analysis for detecting cluster of cases.

BACKGROUND: Contamination and transmission of different Listeria monocytogenes strains along food chain are a serious threat to public health and food safety. Understanding the distribution of diseases in time and space-time is fundamental in the epidemiological study and in preventive medicine programs. The aim of this study is to estimate listeriosis incidence along 10-years period and to perform space-time cluster analysis of listeriosis cases in Marche Region, Italy. METHODS: The number of observed listeriosis cases/year was derived from regional data of surveillance of notifiable diseases and hospital discharge form. The capture and recapture method (C-R method) was applied to estimate the real incidence of listeriosis cases in Marche Region and the space-time scan statistics analysis was performed to detect clusters of space-time of listeriosis cases and add precision to the conventional epidemiological analysis. RESULTS: The C-R method estimation of listeriosis cases was 119 in the 10- year period (2010-2019), with an average of 31.93 % of unobserved cases (lost cases). The estimated mean annual incidence of listeriosis was 0.77 per 100,000 inhabitants (95 %CI 0.65-0.92), accounting for 6.07 % of additional listeriosis cases per year than observed cases. Using the scan statistic, the two most likely clusters were identified, one of these was statistically significant (p < 0.05). The underdiagnosis and under-reporting in addition to listeriosis incidence variability suggested that the surveillance system of Marche Region should be improved. CONCLUSIONS: This study provides evidence of the ability of space-time cluster analysis to complement traditional surveillance of food-borne diseases and to understand the local risk factors by implementing timely targeted interventions.

Population-level benefits of increasing influenza vaccination uptake among Italian older adults: results from a granular panel model.

Background: The impact of seasonal influenza vaccination (SIV) on mortality is still controversial; some studies have claimed that increasing vaccination coverage rates is beneficial, while others have found no significant association. This study aimed to construct a granular longitudinal dataset of local VCRs and assess their effect on pneumonia- and influenza-related (P&I) mortality among Italian adults aged ≥ 65 years. Methods: NUTS-3 (nomenclature of territorial units for statistics) level data on SIV coverage were collected via a survey of local data holders. Fixed- and random-effects panel regression modeling, when adjusted for potential confounders, was performed to assess the association between local SIV coverage rates and P&I mortality in older adults. Results: A total of 1,144 local VCRs from 2003 to 2019 were ascertained. In the fully adjusted fixed-effects model, each 1% increase in vaccination coverage was associated (P < 0.001) with a 0.6% (95% CI: 0.3-0.9%) average over-time decrease in P&I mortality. With an annual average of 9,293 P&I deaths in Italy, this model suggested that 56 deaths could have been avoided each year by increasing SIV coverage by 1%. The random-effects model produced similar results. The base-case results were robust in a sensitivity analysis. Conclusion: Over the last two decades, Italian jurisdictions with higher SIV uptake had, on average, fewer P&I deaths among older adults. Local policy-makers should implement effective strategies to increase SIV coverage in the Italian senior population.

Ten Actions to Counteract Vaccine Hesitancy Suggested by the Italian Society of Hygiene, Preventive Medicine, and Public Health.

Vaccine hesitancy (VH) is one of the main causes of the widespread decline in vaccination coverage and has become the subject of ongoing debate among public health professionals. The present commentary is a "decalogue" of strategic actions to counteract vaccine hesitancy for public health professionals that comes from the cognitive and formative path put in place by the "Communication in Public Health" working group (WG) of the Italian Society of Hygiene, Preventive Medicine, and Public Health. From the establishment of a national, multidisciplinary WG on VH to the activation of a national monitoring/surveillance system on vaccine hesitancy, several proposals are discussed. The identification and dissemination of good practices and tools to counteract and understand vaccine hesitancy, interdisciplinary training on vaccine hesitancy and on risk communication, community engagement and infodemiology, the inclusion of effective interventions to counteract vaccine hesitancy within the National Immunization Plan (NIP), the promotion and growth of a community of practice and research in the field of vaccine hesitancy, collaborations between scientific societies, and knowledge from the behavioral sciences represent other actions recommended in the present commentary. The present document suggests ten undeferrable strategies that could be implemented at the national and local levels in Italy, and that could be borrowed by other European countries in order to counteract vaccines hesitancy with a systematic and organic approach.

Health Communication in COVID-19 Era: Experiences from the Italian VaccinarSì Network Websites.

In 2013, in a bid to combat Vaccine Hesitancy (VH) and provide information on vaccines by communicating with the general public and the health community (e.g., healthcare workers and public health operators), the Italian Society of Hygiene and Preventive Medicine (S.It.I.) published the national website "VaccinarSì". The project was subsequently extended to ten Italian Regions. This led to the creation of the VaccinarSì Network, whose websites are publicly owned. The aim of this work was to present the framework of the websites of the VaccinarSì Network and to analyse user behaviour in the pre-COVID-19-era (dating from each website's publication until 31 January 2020) and in the COVID-19-era (from 1 February 2020 to 31 January 2021). Some metrics such as the number of visits to the site (sessions, number of users and average session duration), user behaviour (pages viewed, bounce rate and organic search) and the session acquisition path (direct traffic, referrals and social traffic) were searched, extrapolated and processed with Google Analytics. Qualitative and normally distributed quantitative variables were summarised with their absolute (relative) frequencies and means. Statistical differences between the means of the two periods were evaluated through paired t-test. A two-tailed p-value less than 0.05 was considered to be statistically significant. When the total values recorded over the period were compared, an overall increase in metrics was observed-the number of individual users, visits and individual pageviews rose in a statistically significant way. Our study aimed to highlight how combining disciplines such as health education and digital communication via Information and Communication Technologies (ICT) represents the best strategy to support citizens. This approach gives them the tools to become independent and responsible players that are capable of voluntarily and consciously choosing to adhere to vaccination programs. The VaccinarSì Network's goal for the future is to reach an even wider audience. By building each user's critical knowledge, this network enables users to be active components of a wider, more empowered community.

[Epidemiology and surveillance of hepatitis E in Italy: data from the SEIEVA surveillance system 2007-2019]. / Epidemiologia e sorveglianza dell'epatite E in Italia: dati dalla sorveglianza SEIEVA 2007-2019.

BACKGROUND: hepatitis E is a disease spread all over the world, with endemic levels varying according to ecological and socioeconomic factors. In developing countries, large epidemics spread mainly through contaminated water; in developed countries, hepatitis E has always been considered a sporadic disease, closely associated to the travels to endemic areas, especially in Southeastern Asia. In the last years, this perception is significantly changing, because of an increasing number of autochthonous cases reported in many European countries. OBJECTIVES: to describe the epidemiological picture of hepatitis E in Italy from 2007 to 2019. DESIGN: descriptive study based on the cases reported to the special surveillance of acute viral hepatitis (SEIEVA); case-control analytical study for the analysis of risk factors associated with hepatitis E. SETTING AND PARTICIPANTS: hepatitis E cases reported to SEIEVA in the period 2007-2019. MAIN OUTCOME MEASURES: number of cases notified by year, percentages of cases exposed to known risk factors, odds ratios. RESULTS: from January 2007 to June 2019, 385 hepatitis E cases were notified to SEIEVA. The annual number increased from 12 in 2007 to 49 in 2018, the increasing trend continued in 2019, when 39 cases were observed in the first 6 months of the year. Northern and Central Regions reported most of the cases; only a few were diagnosed in Southern Regions. Based on SEIEVA data, the trend of hepatitis E notifications has increased according to the increasing propensity to the differentiated diagnosis, at least until 2018. However, only 46% of suspected cases are tested to detect the presence of anti-HEV IgM antibodies, during the observation period; the percentage of tested cases is significantly lower in the South than in Northern and Central Italy (p<0.001). The reported cases have a median age of 48 years (range: 5-87) and are mostly males (80%); 32% was observed in foreign citizens mainly from endemic areas of South Asia (Bangladesh, India, and Pakistan). In 72.5% of cases, the infection was contracted in Italy. The most frequent risk factor is the consumption of raw or undercooked pork meat, especially sausages (70% of cases), significantly associated with hepatitis E risk (OR 3.0; IC95% 1.4-6.1). Other important risk factors are wild boar sausages consumption (40% of cases, OR 4.6, not statistically significant), and travels to endemic areas during the six weeks before the disease (31% of cases, OR 3.2; IC95% 1.6-6.4). CONCLUSIONS: hepatitis E can now be considered as endemic even in industrialized countries. In Italy, from 2007 an increasing number of cases has been reported. However, the real impact of HEV infection is still underestimated due to the limited number of clinical centres which perform tests for the search of anti-HEV IgM antibodies in cases of acute hepatitis. An ad hoc surveillance has been activated in January 2019 in some Local Health Units/Regions and extended to a national level starting from January 2020. This initiative is necessary in order to better dimension the burden of the disease associated with HEV infection, to study its epidemiology, and to increase awareness of this infection among health professionals.

Parental vaccine hesitancy in Italy - Results from a national survey.

In Italy, in 2016, we conducted a cross-sectional survey to estimate vaccine hesitancy and investigate its determinants among parents of children aged 16-36 months. Data on parental attitudes and beliefs about vaccinations were collected through a questionnaire administered online or self-administered at pediatricians' offices and nurseries. Parents were classified as pro-vaccine, vaccine-hesitant or anti-vaccine, according to self-reported tetanus and measles vaccination status of their child. Multivariable logistic regression was used to investigate factors associated with hesitancy. A total of 3130 questionnaires were analysed: 83.7% of parents were pro-vaccine, 15.6% vaccine-hesitant and 0.7% anti-vaccine. Safety concerns are the main reported reason for refusing (38.1%) or interrupting (42.4%) vaccination. Anti-vaccine and hesitant parents are significantly more afraid than pro-vaccine parents of short-term (85.7 and 79.7% vs 60.4%) and long-term (95.2 and 72.3% vs 43.7%) vaccine adverse reactions. Most pro-vaccine and hesitant parents agree about the benefits of vaccinations. Family pediatricians are considered a reliable source of information by most pro-vaccine and hesitant parents (96.9 and 83.3% respectively), against 45% of anti-vaccine parents. The main factors associated with hesitancy were found to be: not having received from a paediatrician a recommendation to fully vaccinate their child [adjusted odds ratio (AOR): 3.21, 95% CI: 2.14-4.79], having received discordant opinions on vaccinations (AOR: 1.64, 95% CI: 1.11-2.43), having met parents of children who experienced serious adverse reactions (AOR: 1.49, 95% CI: 1.03-2.15), and mainly using non-traditional medical treatments (AOR: 2.05, 95% CI: 1.31-3.19). Vaccine safety is perceived as a concern by all parents, although more so by hesitant and anti-vaccine parents. Similarly to pro-vaccine parents, hesitant parents consider vaccination an important prevention tool and trust their family pediatricians, suggesting that they could benefit from appropriate communication interventions. Training health professionals and providing homogenous information about vaccinations, in line with national recommendations, are crucial for responding to their concerns.
