“Every time you practice shelter in place, every time you practice social distancing, you’re reducing the spread of this disease and you’re saving lives, you’re protecting people, you’re reducing the number of people who end up in the hospital, the number of people who end up fighting for their lives in the ICUs,” Mayor de Blasio said. “If we don’t get it right or God forbid this disease resurges, we’re going to have to potentially tighten restrictions further.”
