The study, published Dec. 15 in the Psychics of Fluids journal, was conducted so that researchers could “analyze the dispersion of cough-generated droplets in the wake of a walking person for different space sizes.” Using simulated airflow, researchers found that six feet of distance may not actually be far enough, depending on the shape of a space. They found that infected particles can be left behind by moving people in a “cloud of droplets.” And when a person coughs in a narrow, enclosed corridor, this cloud is left behind and becomes concentrated—making it more dangerous for those who subsequently walk through it than it would in a larger, open air space. “This poses a great challenge on determining the safe distance for places with high space constraint, [such as] in a very narrow corridor—as a person may still inhale viral droplets even if the patient is far in front of him or her,” the study stated. Spaces such as narrow school hallways, enclosed airport boarding zones, and office corridors can pose a higher risk for COVID spread, Inverse reports. “A slight difference in the airflow can significantly alter the virus spreading pattern in the air,” study co-author Xiaolei Yang, PhD, a researcher at the Institute of Mechanics at the Chinese Academy of Sciences, told Inverse. “You should wear a face mask even if you cannot see people around.” Of course, walking through a narrow hallway isn’t the only way you’re putting yourself at a higher risk of contracting COVID.

Andrew Cuomo presented contact tracing data on Dec. 11, reporting that 74 percent of COVID cases from September to November resulted from private gatherings in people’s homes. This was 10 times higher than what the data found to be the second-highest driver of COVID cases, healthcare delivery. And if you’re worried you’re sick, This Surprising Body Part Can Determine If You Have COVID, Study Says. A meta-analysis out of the University of Florida, which was published in the journal JAMA Network Open on Dec. 14, reviewed 54 studies that spanned 20 countries and nearly 78,000 subjects. In the review, researchers concluded that spouses were responsible for transmission in nearly 38 percent of cases. And for more up-to-date information, sign up for our daily newsletter. A study published in the Science Advances journal on Dec. 4 had researchers use computer models to simulate airflow inside a car that was loosely based on a Toyota Prius with various combinations of windows opened and closed. They found that the combination that led to the highest COVID risk was having all four windows closed while more than one person was in the car.

A study from the Centers for Disease Control and Prevention (CDC) published on Sept. 11 found that “adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results.” And for more coronavirus news, If You Have This Blood Type, You’re at a High Risk of Severe COVID.
