Why isolation at home or other place of residence is necessary?

The main purpose of self-isolation at home or in another place of residence is to prevent the spread of infection and the emergence of new cases. Self-isolation of sick individuals and universal hygiene measures are the most important ways to control this infection. Although people are more likely to be infectious when symptoms occur, it is suspected that some people may transmit the virus before symptoms appear, so isolating a person who has been exposed to COVID-19 (coronavirus infection) is important to prevent the disease from spreading.
