Map of districts from May 10. (Source: Health Ministry) Most measures in the new Covid automat alert system came into force today, setting new conditions for restaurants, shopping centres, fitness centres, water parks and wearing masks and respirators. The most relaxed rules are found in the four districts that switched to the orange tier on Monday, namely the districts of Hlohovec, Nitra, Senec and Topoľčany. Another 50 districts are in the light red tier and 23 in the red tier. Only two districts, Myjava and Sobrance, remain in the dark red tier, meaning the measures there will be the strictest. At the same time, all schools have opened across the country, except for universities. These can open only in the orange districts, with limitations.
