PRAGUE (Reuters) - Nearly half of Slovakia’s entire population took COVID-19 swabs on Saturday, the first day of two-day nationwide testing the government hopes will help reverse a fast rise in infections without a hard lockdown.The scheme, a first in a country of comparable size, is being watched by other nations looking for ways to slow the virus spread and avoid overwhelming their health systems. Defence Minister Jaroslav Nad said on Sunday 2.58 million Slovaks took the test on Saturday, and 25,850 or 1% tested positive and must go into quarantine. The European Union country has 5.5 million people and aims to test as many as possible, except for children under 10. More than 40,000 medics and support teams of soldiers, police, administrative workers and volunteers staffed around 5,000 sites to administer the antigen swab tests.
