According to The New York Times’ data, Connecticut has seen an average of 287 cases per day this past week, which is an increase of 85 percent from the average just two weeks earlier. “In certain regions of the country, like the Midwest the Northwest, and even now we’re starting to see a little difficulty in the Northeast, in New York.

After all, she says indoor activities with the heat on are “particularly conducive to spreading events without your mask.” She recommended residents improve the ventilation in their homes with outside air by keeping fans on and cracking windows whenever possible. “This is the moment to really increase asymptomatic testing, increase outreach to the communities—making sure that every community member knows that if they’re with individuals outside of their household, it could be a COVID-spreading event,” Birx said. “Physically distancing and masks work, even indoors.” And for more up-to-the-minute guidance on COVID, sign up for our daily newsletter.
