SARS-Cov-2 coronavirus causes COVID-19 disease. The disease is most often manifested by fever, coughing, dyspnea, muscle aches, fatigue. The symptoms occur in about 15-20% of people. Other people can go through the disease completely asymptomatic. Unfortunately, at the same time they may infect others unconsciously. It is estimated that the mortality rate for COVID-19 is about 2%.
The virus is transmitted via a droplet, so it is important to avoid contact with other people (who are potentially carriers) and to increase hygiene (especially washing hands more often).
