In Italy, the first case of the coronavirus disease 2019 (COVID-19) was officially reported on 20.02.2020. The disease has since rapidly evolved, causing a public health emergency throughout the country but especially in our region, one of the most widely affected areas. We reorganized the daily routine of our cancer center to reduce the risk of contagion. A temporary tensile structure was set up as an entry-point triage, and a COVID-19 route was created with a dedicated CT scanner. A pre-access telephonic triage was performed the day before a patient was scheduled to come in for an examination. At the time of writing (May 4), 4053 patients had been to our center since the emergency officially began (9.03.2020) and the COVID-19 route had been activated for only 9 paucisymptomatic outpatients and 7 symptomatic inpatients. We also re-evaluated patient radiology examination lists and rescheduled non-urgent tests in consensus with the referring oncologist. Out of a total of 1438 patients scheduled for radiological examinations, 456 were postponed for a total volume reduction of 29.1%. Nine asymptomatic patients with typical CT findings of COVID-19 were identified during routine CTs, but none were RT-PCR-positive for SARS-CoV-2. We guaranteed all urgent and semi-urgent examinations, including those to stage newly diagnosed cancers and to evaluate response to treatment, ensuring the continuation of the diagnostic and therapeutic pathway of our patients. The measures we took were instrumental in keeping the institute COVID-19-free. We also describe the planned measures to resume normal clinical practice at the center. [ABSTRACT FROM AUTHOR]

Italy was the first, among all the European countries, to be strongly hit by the COVID-19 pandemic outbreak caused by the severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2). The virus, proven to be very contagious, infected more than 9 million people worldwide (in June 2020). Nevertheless, it is not clear the role of air pollution and meteorological conditions on virus transmission. In this study, we quantitatively assessed how the meteorological and air quality parameters are correlated to the COVID-19 transmission in two large metropolitan areas in Northern Italy as Milan and Florence and in the autonomous province of Trento. Milan, capital of Lombardy region, it is considered the epicenter of the virus outbreak in Italy. Our main findings highlight that temperature and humidity related variables are negatively correlated to the virus transmission, whereas air pollution (PM2.5) shows a positive correlation (at lesser degree). In other words, COVID-19 pandemic transmission prefers dry and cool environmental conditions, as well as polluted air. For those reasons, the virus might easier spread in unfiltered air-conditioned indoor environments. Those results will be supporting decision makers to contain new possible outbreaks.
