In the future, contact persons of infected persons no longer have to be quarantined if they alread received their third "booster" vaccination, have been doubly vaccinated for less than three months, have been vaccinated and recovered from a Covid infection, or have been fully recovered for less than three months. For all other contact cases and for infected persons, quarantine or isolation should usually end after ten days. After seven days, quarantine can be prematurely ended if one provides a negative PCR or antigen test. Employees in hospitals and nursing homes require a PCR test and must be symptom-free for at least 48 hours.
