The government agreed on Thursday that direct flights can restart between Tallinn and Ukraine after the average number of coronavirus infections fell below 25 per 100,000 inhabitants.
On Thursday (July 23) Wizzair restarted direct flights between Tallinn and the Ukrainian cities of Kyiv, Kharkiv and Lviv.
The average infection rate of the last 14-days in Ukraine is 24.5 per 100,000. In contrast, Estonia's is 1.2 per 100,000.
All passengers traveling from Ukraine to Estonia are required to self-quarantine for 14 days on arrival.
Quarantine is not required if a country's infection rate falls below 16 per 100,000. Airlines can only restart direct flights if the infection rate in the destination country is below 25 per 100,000.
What does quarantine really mean?
The Police and Border Guard Board's (PPA) definition of what a 14-day quarantine period is and what the rules are, is published below:
"It means that a person may not leave his or her place of residence within 14 days, except on the instructions of a healthcare professional or a police officer, or for unavoidable reasons.
"For instance, you may leave home if your life is in danger or you need medical attention, to renew your food supplies, purchase essentials or medicines. In all these cases, you must avoid contact with other people.
"Therefore, you must not go to work or too crowded hiking trails. However, you can, for instance, go running or cycling if you do so without coming into contact with others."
