Coronaviruses (CoV) are a large family of viruses that cause symptoms ranging from the common cold to more serious illnesses, i.e. the Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The new coronavirus (nCoV) is a new strain of coronavirus that had not yet been identified in humans.
COVID-19 is the infectious disease caused by the latest discovered coronavirus (SARS-CoV-2). This new virus and disease were unknown before the outbreak in Wuhan, China, in December 2019.
COVID-19 infection remains mild in 80% of cases. In order to delay spreading among the general population and to protect vulnerable and fragile groups in the population, it is important to take a certain number of precautions.
