Quality of a ventilation in buildings impacts how coronavirus spreads indoors

LA CROSSE, Wis. (WKBT) – With temperatures in the 90’s, people are seeking shelter in buildings with air conditioners on blast.

Which has some wondering, can the air circulation from AC’s spread the coronavirus?

Health experts say what it really comes down to is the quality of a building’s ventilation, not the A.C.

Poor ventilation puts people more at risk of getting infected, especially if the room is crowded.

“Whether it’s an old building, new building, it comes down to ventilation, which is why I continued to emphasize, even with my family and friends, that the best tool against our disposal against COVID-19 is just to avoid sitting down in restaurants,” said Megan Meller, Infection Preventionist at Gundersen Health System.

Meller says if you have concerns about ventilation in your home, the best thing to do is open up the windows and situate fans in a way that pulls hot, indoor air outside.

One way to do this is by placing a box fan in your window with the blades facing the screen.

However, Meller says the best thing to do is continue social distancing, wearing a face-covering when out, and following other CDC guidelines to prevent getting the virus.
