They will be kept in compulsory quarantine for seven days under the new rules.
Samples will be collected for their corona test later.
If the result is negative, the instruction to stay in quarantine at home will be sent from compulsory quarantine.
If the result is positive, they will be admitted in the government-appointed isolation center.
