Introduction:
The state of epidemic, caused by the SARS CoV-2 virus, introduced in Poland on 20 March 2020, significantly affected the situation of entities conducting medical activities, patients and medical staff. Therefore, the activity of the legislator introducing legal provisions regulating the functioning of the healthcare system under epidemic conditions is not surprising. One of the directions of the changes introduced was to regulate specific principles of conduct in the event of exposure to SARS CoV-2 virus infection, suspicion or diagnosis of infection with this virus, as well as suspicion or diagnosis of the disease caused by it (COVID 19).

Objective:
The aim of the study is to present selected regulations regarding the procedure in the case of exposure to SARS CoV-2 virus infection, suspected or diagnosed infection with this virus, as well as suspected or diagnosed disease caused by it (COVID 19).

Materials and method:
Acts of universally binding law on preventing and combatting infections and infectious diseases in Poland and Acts of universally binding law adopted in connection with the spread of SARS CoV-2 virus were used. The method of analysing legal Acts and references was used.

Conclusions:
In the case of airborne diseases in people, limiting the spread of an infectious agent is inseparably connected with the need to limit contact of infected people or people suspected of contact with an infectious agent with healthy people. This, in turn, would not be possible without mechanisms guaranteeing effective and sufficient isolation of these people. Due to the nature of these activities, they must be associated with a limitation of basic personal rights, such as freedom of movement or voluntary submission to diagnostic or therapeutic procedures.
