After recruiting 142 flu patients, researchers at the University of Maryland analyzed the air around the volunteers for the next three days. They discovered that 48 percent of the samples contained enough virus to infect another person—no coughing required.
“We found that flu cases contaminated the air around them with infectious virus just by breathing, without coughing or sneezing,” explained lead researcher Donald Milton, MD, MPH, professor of environmental health at the University of Maryland School of Public Health in a press release. “People with flu generate infectious aerosols (tiny droplets that stay suspended in the air for a long time) even when they are not coughing, and especially during the first days of illness. So when someone is coming down with influenza, they should go home and not remain in the workplace and infect others.”
What can you do? First, make sure you know the six signs that you might be coming down with something. And get a flu vaccination: It might not be perfect, but it is the best proven protection against those sneaky virus particles floating in the air. Finally, show this to your coworkers and remind them it’s their duty to take time off when they’re sick!
