Five consecutive national vaccination plans (from 1999 to 2025) were revised, outlining their objectives, challenges, and results. Vaccination coverage for children consistently approached target levels, though regional differences emerged. In contrast, coverage for adolescents, the elderly, and vulnerable groups, consistently fell short of targets.

Refugees and migrants remain one of the most vulnerable people and the COVID-19 pandemic has posed additional challenges both in terms of increased risk of infection and death experienced, highlighting existing inequities in access to and utilization of health services, as underlined by World Health Organization in 2020 in the Health and Migration Programme. In the context of the Programme 'Epidemiological surveillance and control of COVID-19 in metropolitan urban areas and for the containment of the circulation of SARS-CoV-2 in the migrant population in Italy', coordinated by the Italian Centre for Disease Control and Prevention (CCM) and funded by the Italian Ministry of Health, an experimental epidemiological, virological, and molecular SARS-CoV-2 surveillance system addressed to migrant populations in Sicily through Mediterranean routes was implemented. To this end, a multidisciplinary network supported by a hub&spoke system of laboratories was established in Sicily Region (Southern Italy), using molecular and Next Generation Sequencing (NGS) techniques to identify different SARS-CoV-2 strains in relation to migration flows.

The emergence of antimicrobic-resistant infectious pathogens and the consequent rising in the incidence and prevalence of demises caused by or associated to infections which are not sensitive to drug treatments is one of today's major global health challenges. Antimicrobial resistance (AMR) can bring to therapeutic failure, infection's persistence and risk of serious illness, in particular in vulnerable populations such as the elderly, patients with neoplastic diseases or the immunocompromised. It is assessed that AMR will induce until 10 million deaths per year by 2050, becoming the leading cause of disease-related deaths.

Article Synopsis
  • * Researchers analyzed data from migrants collected in Sicily between February 2021 and May 2022, using advanced molecular techniques to identify and categorize various SARS-CoV-2 variants present among the population.
  • * The findings revealed 472 full-length virus sequences, identified 12 clades and 31 lineages, and demonstrated the potential of this molecular surveillance to predict emerging variants, which can help shape vaccination and public health strategies.

Introduction: A COVID-19 outbreak occurred at the end of October 2021 among pilgrims returning from Medjugorje (Bosnia and Herzegovina).

Methodology: Whole genome sequencing (WGS) of SARS-CoV-2, epidemiological data, and phylogenetic analysis were used to reconstruct outbreak dynamics.

Results: The results suggest that only in one case, associated with the SARS-CoV-2 sub-lineage AY.
