People are taking precautions as concern about swine flu spreads
Officials in Ukraine have closed schools for three weeks, imposed travel restrictions and are limiting public events as the country battles to stop the spread of swine flu.
More than 60 people are believed to have died of respiratory problems in the past week, and the measures are among the toughest to be implemented in Europe to tackle the virus.
It's still not clear whether all the deaths were caused by swine flu, but the news has sparked panic, and people have started wearing masks across the country.
Appeal for calm
The Ukrainian health minister Vasyl Knyazevych has asked the media only to report the comments of medical experts following a series of misleading reports which fuelled public anxiety.
On national television, he said Ukraine had the same problems as the rest of the world.
He also called on fellow politicians to give people 'a week of silence,' and said there was no need for panic.
However, his calls may already be too late.
255,000 cases of flu and acute respiratory problems have been registered among the 46m population. 15,000 have been hospitalised.
The World Health Organisation says there is no evidence to suggest that Ukraine had a bad outbreak of swine flu, but it has agreed to send a team there to help the country cope.
President Viktor Yushchenko has also appealed for international help.
