[The management of confirmed cases of Covid-19 infection in schools: the experience of the prevention Department of the Azienda Sanitaria Friuli occidentale in the Pordenone area]. / L'attività del Dipartimento di prevenzione ASFO nella gestione dei casi confermati di Covid-19 nelle scuole del territorio pordenonese.

The SARS-Cov-2 pandemic that exploded in 2020 resulted in an exceptional school closure involving at least 188 countries worldwide, leaving more than 90% of children at home. This event excluded children and teenagers from the opportunity to learn, socialize, experiment and increased early school leaving. In light of these premises, during the summer months of 2020 the Azienda sanitaria Friuli Occidentale (AsFO) decided to set up a working group to accompany schools in the prevention and containment of the spread of the SARS-CoV-2 infection in the course of the school year 2020-21, with the aim of guaranteeing the right to study and favoring teaching activities in presence in the highest conditions of health and safety. The school reality of the Pordenone area is made up of 40 Comprehensive Institutes for a total of about 206 school complexes of all levels (public, equal and private). In total, the local school population is about 33,000 pupils and 4,000 units of school staff (teachers, ATA, etc ...). The activities of the Schools Group were analyzed by monitoring all interventions with carrying out rapid antigen tests at school and by assessing the incidence of infections within schools. From September 2020 to June 2021, the AsFO Schools Group participated in about 35 teaching colleges and more than 10 dedicated meetings with the families of school pupils of all levels. In total, 170 interventions with rapid antigen tests were carried out at school, involving all the schools in the Pordenone area and a total of 206 classes. During the interventions at school, a total of 6,370 rapid antigen tests were carried out, of which 70% concerned pupils (4,458 total tests) and 30% concerned school staff (1,912 total tests). The antigen tests carried out at school found 173 total positivity (equal to 3% of all tests carried out at school). Out of 173 positives found, 121 are students (70% of the total) and 52 are school staff (30% of the total). During the observation period, the results of the interventions with rapid antigen tests carried out at school led to the continuation of the teaching activity in the presence (with respect to the hygiene and behavioral measures defined by the DP) in 69% of cases (118 interventions). In 9% of cases (15 interventions) the "cross" quarantine was carried out, while in 17% of cases (29 interventions) the quarantine was established for the entire class / section. In 7 circumstances, following the intervention at school, quarantine was established for several classes. Only in 4 circumstances was the institution of quarantine for all school staff, a situation that led to the interruption of all educational activities for the quarantine period.

An updating of the occurrence of canine heartworm disease in northern Italy.

A survey was carried out in northern Italy (Veneto and Friuli Venezia Giulia Regions) to assess the extension of canine heartworm disease close to the classic hyperendemic areas of the Po Valley. A filtration test on 275 privately owned dogs showed a mean prevalence of 44%, with a peak of 55% in the Venice province. A high prevalence (17%) of occult filariosis was discovered using a serological test. These values fall within the medium-high range previously reported from other Italian areas. The provinces of Pordenone, Udine, Trieste, Treviso and Belluno, where no cases had been previously reported, were found to be infected. The distribution of the infection did not differ significantly with the dogs' origin or sex. The prevalence seemed to be influenced significantly (p < 0.01) by the hosts' age, function and degree of outdoor activity, reflecting the different exposure risks.
