Infection was brought from Russia by a long-distance driver
As the border with Russia is closed and only Estonian citizens coming from Russia, or those who have a permanent Estonian residence permit, can cross, ERR asked the Health Board who the carrier of the infection was.
Eike Kingsepp, a spokesperson for the Health Board, said the person was a long-distance driver. The man crossed the border while performing work duties as entry to Estonia for long-distance freight is still allowed.
At the end of June, the driver attended a birthday party with friends and relatives in Narva-Jõesuu. According to current data, the party was attended by about a dozen people.
Kingsepp could not say why the symptoms had not been detected at the border. "He may have hidden them, but it has now been confirmed that he had obvious signs of illness."
Kingsepp said this was an avoidable transmission of the disease.
