Town population size and structuring into villages and households drive infectious disease risks in pre-healthcare Finland

2021

Social life is often considered to cost in terms of increased parasite or pathogen risk. However, evidence for this in the wild remains equivocal, possibly because populations and social groups are often structured, which affects the local transmission and extinction of diseases. We test how the structuring of towns into villages and households influenced the risk of dying from three easily diagnosable infectious diseases—smallpox, pertussis and measles—using a novel dataset covering almost all of Finland in the pre-healthcare era (1800–1850). Consistent with previous results, the risk of dying from all three diseases increased with the local population size. However, the division of towns …

Measles in Italy: Viral strains and crossing borders

2019

In 2017, Italy experienced one of the largest outbreaks of measles in recent years, with 5404 notified cases and 4347 confirmed cases. A further 2029 cases were notified during the first 6 months of 2018, and 1516 of them were laboratory-confirmed. The B3 and D8 genotypes were identified as those responsible for the outbreak. Possible transmission routes can be established by monitoring the circulating measles virus strains in support of the national health authorities to warn people and travellers.

Case-based surveillance of measles in Sicily during 2012-2017: The changing molecular epidemiology and implications for vaccine strategies.

2018

Following the indication of the World Health Organization, a national plan for the elimination of measles was approved in Italy and this included the improvement of the molecular surveil- lance of measles viruses and the interruption of indigenous transmission of the disease. Nevertheless, large outbreaks continue to occur in almost all regions of the country, includ- ing Sicily. Here we describe the epidemiology and molecular dynamics of measles viruses as a result of the measles surveillance activity carried out by the “Reference Laboratory for Measles and Rubella” in Sicily over a 5-year period. Biological samples of 259 suspected measles cases were tested for viral RNA detection and a t…

Immunization Status against Measles of Health-Care Workers Operating at Three Sicilian University Hospitals: An Observational Study

2019

Measles is a highly contagious vaccine-preventable disease (VPD) that also commonly affects health-care workers (HCWs). Measles immunization of HCWs was strongly recommended by international health authorities, in order to limit the spreading of the illness to susceptible patients and colleagues. An observational study, evaluating the immunization and vaccination status against measles of HCWs working at three Sicilian university hospitals, was conducted. All subjects not completely immune (vaccinated with only one dose in their lifetime), not immune (not vaccinated or not naturally immunized), and with an unknown immunization status were considered not immunized. Among HCWs operating in th…

Vaccination and Vaccine Effectiveness: A Commentary of Special Issue Editors

2020

The Special Issue “Vaccination and Vaccine Effectiveness”, published in the journal Vaccines, has the main aim to increase international literature data on vaccine effectiveness and safety and on vaccination strategies in order to reduce vaccine hesitancy and improve vaccination coverage rates. The main topics included in the call for papers were vaccines administered to infants, adolescents, adults, elderly people, at-risk populations (due to comorbidities and personal risk factors) and healthcare workers and strategies adopted to promote vaccination adherence among these categories. This Special Issue started from the assumption that, despite vaccination being universally recognized as on…

Las enfermedades exantemáticas: el sarampión y la escarlatina en las revistas pediátricas españolas (1900-1950)

2013

La revolución microbiológica de finales del siglo XIX supuso un cambio profundo en el abordaje tanto de la patología, la clínica y la terapéutica de las enfermedades infecciosas, como en la medicina preventiva y la epidemiología. Este nuevo enfoque restó protagonismo al pensamiento hipocrático sobre los aires, las aguas y los lugares, que aún influía en el estudio de las enfermedades. Desde esta perspectiva este trabajo se propone mostrar dos enfermedades exantemáticas, sarampión y escarlatina, caracterizadas por una gran morbi-mortalidad, y de las que hasta la fecha no se ha realizado un examen profundo en historia de la medicina española. Para conseguirlo se han recogido las publicaciones…

Fatal measles as AIDS presentation in Italy

Characterization of measles virus strains circulating in Southern Italy (Palermo area, Sicily) between 2010 and 2011

2015

Measles virus (MV) was classified in 24 genotypes that show a distinct geographic distribution. Genotypes contain multiple distinct lineages. In 2011 large outbreaks of measles occurred in Italy and in many European countries. Aims of this study are to analyze the intra-genotype variability and to follow the importation and the spread of new MV strains in Sicily. A fragment of 450. bps of MV C-terminal nucleoprotein was sequenced from sera of 73 Sicilian patients with symptomatic measles infections, occurred between 2010 and 2011. Five MV strains were D4 genotype and 68 were D8 genotype. The MV/D4 sequences were related to MV/D4-Enfield variant. Two lineages of MV/D8 genotypes, related to M…

Factors associated with poor adherence to MMR vaccination in parents who follow vaccination schedule.

2014

Due to median vaccination coverage far from elimination level, Italy is still an European country with high number of measles cases per million of people. In this study we explored potential socioeconomic, medical and demographic factors which could influence the propensity of family members for measles vaccination schedule. A cross-sectional study was performed through a questionnaire administered to the parents of children who received the first dose of MMR vaccine in two different vaccination centers in the Palermo area from November 2012 to May 2013. Overall, the role played by internet (OR 19.8 P = 0.001) and the large number of children in a family (OR 7.3 P ≤ 0.001) were the factors …
