Abstract

This study focuses on the description of positive contagious by SARS-CoV-2 through the use of computer systems WebGIS. This methodology gives an instantaneous image of pandemic evolution. The analysis was performed on 485 positive subjects with a geolocalization through WebGIS analyses. In particular, we reported the total number of positive subjects since the beginning of the world public emergency. In addition, daily, it is possible to query the system to read the number of positive cases and the rate of positive ones per thousand inhabitants referred to each municipality. Our work could improve the efficiency and performance of testing protocols during the follow up of SARS-CoV-2 positive subjects and provide useful information for the management of control measures aimed to reduce the risk of viral spread.


INTRODUCTION

The spread of the new coronavirus, SARS-CoV-2, introduced the need for the implementation of new effective and health protocols and strategies. On 11 March 2020, the World Health Organization (WHO) officially declared the outbreak of a global pandemic. Healthcare organizations have recommended people not to touch the face and cleaning their hands after touching public surfaces such as handles, handrails, etc to limit the diffusion of contamination (1-3). After the Chinese outbreak, where the SARS-CoV-2 epidemic started, Italy was the second country to be affected by 365,467 positive cases and more than 40,000 deaths (4, 5). 

The symptomatology of the disease was showed by severe interstitial pneumonia and systemic alterations linked to the inflammatory response; while in other cases, although the virus was present, there was no type of symptom. Elderly people, and/or affected by many pathologies, who are affected by COVID 19 can undergo serious respiratory complications, which require hospitalization in intensive care unit and can lead to death: in about 20% of those affected, with large di ...
