The novel coronavirus may be able to travel from person to person through tiny particles floating in the air, according to a recent letter signed by 239 scientists from across the globe. The international team, which includes six faculty members from CU Boulder, lays out evidence showing just how tenacious the pathogen behind COVID-19 can be: the virus, the group says, can likely drift through and survive in the air, especially in crowded, indoor spaces with poor ventilation like many bars and restaurants.
