In a joint study by the University of Nebraska Medical Center (UNMC), the National Strategic Research Institute at the University of Nebraska, and others, researchers found genetic material from the virus that causes COVID-19 in air samples from both in and outside of confirmed coronavirus patients’ rooms. The findings offer “limited evidence that some potential for airborne transmission exists,” researchers said, though they warned that the findings do not confirm airborne spread.
Researchers, looking to better understand viral shedding of the novel virus, took air and surface samples from 11 patients’ rooms during the initial isolation of 13 people who tested positive for COVID-19. The researchers found virus genetic material on commonly used items, such as toilets, but also in air samples, thus indicating that “SARS-CoV-2 is widely disseminated in the environment.” (SARS-CoV-2 is the name of the virus that causes COVID-19.)
Not only was the virus detected within COVID-19 patients’ rooms, “air samplers from hallways outside of rooms where [the] staff was moving in and out of doors were also positive,” they wrote.
“These findings indicate that disease might be spread through both direct (droplet and person-to-person) as well as indirect contact (contaminated objects and airborne transmission) and suggests airborne isolation precautions could be appropriate,” they concluded, noting that the findings also suggest that COVID-19 patients, even those who are only mildly ill, “may create aerosols of virus and contaminate surfaces that may pose a risk for transmission.” – READ MORE
