Research shows that closed
spaces where people go to escape the summer heat—especially when crowded with people close together—may be ideal locations for #coronavirus spread.
experts eye impact of air conditioning
"Anytime we are going into a closed environment
, we are at higher risk."
scientists are warily watching what potential impact retreating into air conditioned spaces
may be having on the further spread of the virus.
a growing body of research suggests that indoor spaces with poor ventilation
or lack of new air
can raise the risk of the virus' spread,
most concerned about people “going to a cooling center where ... the air conditioning
is not filtering air or bringing in outside air -
- and a lot of people are close together.”
...scientists published earlier this month that looked at the spread of the influenza virus, which causes the seasonal flu.
The research found that the flu virus might be spread through the air, as fine droplets, rather than through large droplet
spray, as was previously believed.
Moreover, the research revealed the virus’s infection rate appeared to drop in well-ventilated areas
. Since both influenza and COVID-19 are respiratory viruses, Milton said his findings could mean that the types of closed spaces people typically go to escape the summer heat, when crowded with people close together, could also be ideal locations for virus spread.
And though Milton said he was especially concerned about cooling centers, a study recently published by researchers at the University of Minnesota and undergoing peer review suggested that the particular indoor setting and even the position of the ventilation could impact how well it did against potential viral-containing particles. With schools scrambling to prepare for fall, the University of Minnesota study included a classroom simulation.
