Nine new cases of coronavirus were recorded in the last 24 hours, the Health Board said on Thursday. In total, 686 tests were analyzed.
Two cases in Narva are related to a person who visited the city while displaying clear symptoms of the virus. Another case in Narva is still being determined.
There were an additional two cases in Tartu and three in Harju County related to a person who visited shops, a spa and a cinema in Tartu. There was also one case discovered in Järva County.
The Health Board announced on Thursday that the number of new cases could jump in the coming days as close to 50 people have been determined as coming into close contact with the known infected persons.
Tiia Luht, the head of the Southern Regional Department of the Health Board, said all eight cases of COVID-19 in Tartu are related to a case on July 24, where a person displaying symptoms of the virus visited a night club.
Luht said: "As the circle of contacts is rather large, we can unfortunately predict a steady increase in new cases."
She added that restrictions will be set if the infection rate in Estonia will exceed 25 per 100,000 persons over 14 days.
Urmas Klaas, Mayor of Tartu, said the outbreak in Tartu is very unfortunate: "The irresponsibility of one person can endanger the health of many. The behavior of everyone affects whether the virus will gain strength in Tartu or if we can limit it."
A total of 118,576 tests have been carried out in Estonia since February, of which 2,051 have been confirmed as the SARS-CoV-2 virus.
As of Thursday morning, four people are being treated in hospital - an increase of one from Wednesday - and there are estimated to be 35 active cases in the country. So far, 393 people have been discharged from hospital.
There were no deaths reported, leaving the total at 69. The last death recorded was on June 2.
The Health Board reminds everyone that even after the end of the emergency situation, vigilance towards COVID-19 as well as other infectious diseases should stay high: hand hygiene, social distancing and staying home when sick are still important measures to follow. The coronavirus is spread mainly from person-to-person, usually via close contact with an infected person. Close contact is seen as a situation where people are closer than two meters to each other for 15 minutes.
