Prime Minister Boyko Borissov appealed to Bulgarians to follow the rules, saying that on Thursday alone, 14 people that were supposed to be under quarantine did not observe it.
"We want this state of emergency for one month," Borissov told parliament. "We need it for those who violate quarantine."
The Bulgarian parliament voted unanimously on Friday to declare a state of emergency until April 13 to contain the spread of coronavirus after the number of confirmed cases in the country more than tripled to 23.
The Balkan country confirmed its first death of a patient due to the virus on Wednesday, and on Thursday, the number of confirmed cases jumped to 23 from 7.
The state of emergency will allow for travel bans to and from countries with large coronavirus outbreaks, the closing of schools and universities, and permit police to intervene when imposed isolation of infected people is not observed.
