Air conditioning units could be spreading COVID-19 in Florida, according to Harvard epidemiologist

 

TAMPA, Fla. — Air conditioning units, especially in corporate settings, may be contributing to the spread of COVID-19 in the southern part of the United States, according to a Harvard epidemiologist.

 

Dr. Edward Nardell is a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health. He's done in-depth research on how air conditioning units contribute to the spread of airborne infections.

 

Nardell said air conditioning can help airborne viruses spread in three ways.

 

First, people go inside to cool down, when you are much safer outdoors, Nardell said. Now, we're seeing more people indoors because of the high heat and humidity, specifically in the southern states like Florida.

 

The second problem is that is air conditioning brings in very little outside air, according to Nardell. While this isn't a major problem inside your own home, it can be especially problematic in corporate settings.

 

"It just isn't economically possible to bring in outside air, recirculate it and dehumidify it," he said.

 

Lastly, he said when people are indoors, you're often not spaced out safely as you would be outdoors.

 

"You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to rebreathing their small particles."

 

Nardell also said air conditioning units can generate air currents that can carry large particles even further, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involving three family clusters.

 

Now, the Centers for Disease Control and Prevention is recommending restaurants increasing the distance between tables and improving ventilation….

There’s No Good Reason To Mask Toddlers

By Georgi Boorman

JULY 9, 2020

 

(Snip)

Parents on Reddit are desperately trying to crowdsource answers: How do I get my stubborn toddler to wear a mask?

 

Parents in some states, such as New York, have no choice but to figure out how to comply with the mask mandate for children older than two years old, or else keep their children out of public spaces indefinitely. Yet despite a near-complete lack of evidence children spread COVID-19 to vulnerable people or are likely to fall seriously ill from it, many parents are following state recommendations to mask their toddlers. Some serious adherents of this orthodoxy are even publicly shaming parents who don’t or can’t mask their little ones.

 

The evidence over the past few months is remarkably consistent around the world that children seldom spread SARS-COV-2, and almost never to adults, even when in extended contact with parents, teachers, and caretakers. Based on what we know, the risk a symptomless child would infect someone, or become infected, while whizzing past grocery shoppers or even sitting behind them on a flight is almost zero.

 

Reporting on the dearth of outbreaks among child care centers, NPR notes there are almost no documented cases of child-to-adult transmission. Children seem to rarely catch the Wuhan virus, and when they do, not only are their symptoms mild, but they are extremely unlikely to pass it on to others.

 

…Before you reach for that toddler-sized mask, ask yourself if that’s the kind of world you want.
