Two hundred schools want to replace preventive antigen testing for Covid-19 with a more accurate PCR method come September, Education Ministry spokeswoman Aneta Lednová said. This represents about 3.6 percent of all primary and secondary schools in the Czech Republic. Schools could sign up for PCR testing until yesterday afternoon, and for one test they will receive CZK 200 back. According to the government's decision, in the first days after the start of the school year, children are preventively tested three times by antigen tests provided by the state. If the school decides to replace them with PCR tests, it will have to arrange the testing itself. Money from the European Union Solidarity Fund will go for PCR tests. According to the ministry's statistics, there are approximately 4,200 primary and 1,300 secondary schools in the Czech Republic. According to Ledová, 354 schools reported the use of PCR tests last school year. The number of schools that have opted for PCR tests is now lower than in the spring. Preventive antigen testing is scheduled for Sept. 1 or 2, as well as Sept. 6 and 9.

The police stated that the state did not suffer any damage when procuring medical devices and that there were no more advantageous alternatives with regard to the protection of life and health at that time, according to Novinky.cz.
