The young mother is thought to be one of the world’s youngest victims of coronavirus and is the sixth person to die in Poland. Polish media reports the woman had given birth just days before at a hospital in the town of Łańcut and had no previous health concerns. It is thought she could have contracted COVID-19 from her mother who had recently returned from a trip to Italy – the country with most coronavirus-related deaths in the world.
Italy overtook China as the country with the most deaths on Thursday.
In the past 24 hours another 627 people have been killed by COVID-19 – taking the total number of casualties in Italy to 4,032.
Around the world there are more than 250,000 cases of coronavirus with over 10,000 deaths.
Poland currently has 411 confirmed cases of coronavirus and 6 deaths.
Polish Prime Minister Mateusz Morawiecki declared a “state of pandemic” this afternoon and announced school would close until after Easter.
The crackdown comes after authorities shut down the border to foreign visitors.
Mr Morawiecki said: “We are today introducing a state of epidemic which gives us new prerogatives but also gives us new responsibilities.
He said: “The speed of our eventual recovery depends entirely on our collective ability to get on top of the virus now and that means we have to take the next steps on scientific advice.
“And following our plan we are strengthening the measures announced on Monday.
“We need now to push down further on that curve of transmission between us.”
