COVID-19 is the infectious disease caused by the latest discovered coronavirus SARS-CoV-2. 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). 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. However, vulnerable people run a greater risk of developing severe symptoms. In order to delay spreading among the general population and to protect vulnerable and fragile groups in the population, it is essential to apply the protective measures, since there is currently no treatment for the disease.
