Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.

 Respiratory symptoms ranging from mild to moderate appear on most of those infected with the virus and recover without the need for special therapeutic intervention.  However, some of those who become infected develop severe symptoms and require medical attention.  Those with underlying diseases, such as cardiovascular disease, diabetes mellitus, chronic respiratory disease, cancer and other diseases, are most likely to develop severe symptoms of the disease.  However, anyone of any age is at risk of severe illness and death from COVID-19.

 The best way to prevent and slow the transmission of COVID-19 infection remains to be familiar with the characteristics of the disease and the way the virus is spread.  Precautionary measures to protect yourself and others from infection include: distancing at least one meter from others, wearing a well-fixed mask, and regularly washing hands or rubbing them with an alcohol disinfectant.  Also, get vaccinated when it's your turn and follow local authorities' instructions.
