"Potentially you could be shedding more virus in your upper respiratory tract than you would be if most of the replication was happening deep in your lungs," says Angie Rasmussen, a virologist at the University of Saskatchewan in Canada. flex-wrap: wrap; This highlights the importance of wearing a mask in situations where people cannot physically distance, he added. The findings suggest that the spread of omicron could hinge, in part, on the fact that more vaccinated people are contagious and shedding virus, not necessarily that each infected individual is releasing a lot more virus into the air. background-color: #ffffff; When you move further away, not only is the aerosol diluted down, theres also less infectious virus because the virus has lost infectivity [as a result of time].. Previous studies relied on spraying virus into rotating sealed chambers to create an aerosolized environment. update_covid_half_life(); Quantitative microbial risk assessment (QMRA) studies have been conducted to understand and characterize the relative risk of SARS-CoV-2 fomite transmission and evaluate the need for and effectiveness of prevention measures to reduce risk. Someone can also be exposed via splashes and sprays of respiratory fluids directly onto their mucous membranes. } Research suggests the answer is yes: Particles can linger for anywhere from minutes to hours, the CDC says. Mayo Clinic Minute: How dirty are common surfaces? Accessed Feb. 23, 2022.
