ATHENS, Greece (AP) — Kits for self-administered coronavirus tests have begun arriving in Greek pharmacies, with residents entitled to one kit free of charge per week as part of efforts to tackle a surge of coronavirus cases and hospitalizations. Priority for the home tests is initially being given to teachers and high school students aged 16-18, as authorities announced plans to reopen high schools for students in the final three grades starting April 12. Students and teachers returning to school will be required to use the test kits twice weekly. Greece has been in lockdown since early November and schools have been shut for most of the time since then.
