Poland, Ukraine and Bulgaria have reported record numbers of coronavirus infections and deaths, as European countries face new waves of cases and are forced to return to lockdown measures.
The lack of doses of vaccines against this virus is also worsening the situation.
Ukraine, the largest country in Eastern Europe, has reported 24 deaths from the coronavirus on March 342.
Bulgaria, on the other hand, has recorded record numbers of infections within the day, 4,851.
In Central Europe, Poland has registered 29,978 coronavirus infections in the last 24 hours - a record number since the outbreak of the pandemic - so the government has pledged to tighten the partial lockdown.

Health Minister Adam Niedzielski has said that the situation is serious in Mazovia, the central region that includes the capital Warsaw, and the industrial region of Silesia.
"Unfortunately, these signs today are pushing us to think very seriously about tightening the measures. We are thinking about whether we should do something like this on a regional or national level", said Niedzielski for the Wirtualna Polska network.
Polish Prime Minister Mateusz Morawiecki has said that the new restrictions will be introduced on March 25.
Earlier this month, Poland reinstated a series of measures to combat the wave of infection, closing schools, shopping malls and theaters.
In Germany, Chancellor Angela Merkel has overturned a decision for tougher measures against the coronavirus in time for the Easter holiday, following fierce criticism, the dpa news agency reported on March 24.
The withdrawal of the decision came a few hours after the restrictions were announced, as a result of the increase in the number of infected people in this country.

Meanwhile, the European Union is expected to propose new rules that could potentially block the export of coronavirus vaccines to Britain and other countries, following shortages of sufficient doses within the EU itself.
