As the pandemic continues brought on by Covid-19, new information is emerging about how it is spread. To the concern of many, there’s increasing evidence that SARS-CoV-2, the specific coronavirus associated with the Covid-19 pandemic, can spread from person to person through the air, especially among people who occupy enclosed, crowded spaces with poor ventilation for prolonged periods.Although it wasn’t the case when Covid-19 first emerged in early 2020, scientists and healthcare professionals worldwide now generally agree that Covid-19 can be spread through shared indoor air, particularly as more contagious variants of the coronavirus continue to be discovered.
