More dangerous to dance in a disco or kiss a stranger? “It’s like Russian Roulette either way.” Thus the virologist Fabrizio Pregliasco to the microphones of ‘A sheep’s day’ on Rai Radio1. “With the dance you stay close, you increase the respiratory rate, there is crowding. In short – explains Pregliasco – it is not a good situation. To dance you should be more than a meter away and therefore be few on the dance floor. . For kisses, however, better between those who have had two doses of vaccine “.
