This Is Where You're Most Likely to Catch COVID, New Study Says

Researchers found that these high-risk places should be avoided during the pandemic.

Tackling the coronavirus pandemic has meant greatly changing the way we live our daily lives in order to slow the spread. And while the risk of becoming infected changes with each situation, the sliding scale of which places to be avoided becomes more apparent with each new scientific study. This includes new research, which found that crowded indoor events were far and away where you're most likely to catch COVID. Read on to see what else the study uncovered, and for more on things that could be protecting you from the novel coronavirus, check out If You Have This in Your Blood, You May Be Safe From COVID, Study Says.

A three-month-long study commissioned by Otis Worldwide and conducted by researchers at Purdue University examined how airflow affected the risk factors of everyday activities such as grocery shopping, exercising, dining at a restaurant, and riding in an elevator. When simple mitigation efforts such as air purification systems and the use of face masks were factored into each situation, results showed that almost all situations became safer. Beyond that, the length of time spent in some places also makes them riskier.

"We compared the relative exposure risk of elevators to other common activities in a typical workday, including an hour-long bus ride and eight hours in an office environment," Qingyan Chen, PhD, lead researcher on the study and James G. Dwyer Professor of Mechanical Engineering at Purdue, said in a statement. "Riding an elevator was a lower exposure risk activity, given the short duration of an elevator ride."

Others involved with the study pointed out how simple health protocols could greatly reduce the chances of becoming infected—even in a small, seemingly confined space such as an elevator. "As long as people follow other guidance, they can bring the risks down. We still want people to wear masks just like everywhere else," Otis CEO Judy Marks said during a Feb. 1 appearance on CNBC's Mad Money. "Wear them in your elevators and, truly, the analysis and the data and the science show that you are less potential for risk than outdoor dining, much closer to grocery shopping."

But the study was also able to calculate a "risk level of exposure" for other places and situations based on the "intensity of exposure," the "frequency of exposure," and the "duration of exposure."
