“We are concerned that both Baltimore and Atlanta remain at a very high level,” Birx said on the call. “Kansas City, Portland, Omaha, of course what we talked about in the Central Valley (in California).”
“We are seeing a slow uptick in test positivity in cases in places like Chicago, Boston and Detroit and DC,” she said, adding that the virus has entered a new phase.
“This outbreak is different from the March, April outbreak in that it’s in both rural and urban areas,” Birx said.
In Wednesday’s call, she said the concern last week centered on increasing numbers in Tennessee, Kentucky, Indiana, Ohio, Illinois and Virginia.
“Although we’re seeing improvements in some of the red states and some of the states have actually moved from being in a red category — that was more than 10% test positivity — to under 10%, Kentucky, Tennessee and Virginia moved back into the yellow states status,” Birx said. “Their work needs to continue to intensify to continue to bring down case counts.”
Now, Birx said, Nebraska and California have moved into the red category, with more than 10% of tests coming back positive. She said Los Angeles may have seen improvements but that there’s significant movement of the virus up California’s Central Valley.
Despite Birx’s quick reference to 10% positive test rates, it’s not entirely clear which states the task force has designated as “red,” “yellow” or “green,” how often that label may change or what the criteria may be for the designation because the panel hasn’t released the information on the classification system.
Birx said Wednesday that she has crisscrossed the country over the past five or six weeks, driving about 6,000 miles, and has seen a few trends for herself.
“We’ve really seen that America is on the move and people are going on vacation,” she said. She urged officials on the call to draw attention in their state to the dangers of exposing older family members to returning vacationers because of wide asymptomatic spread.
Birx again blamed “super spreader” events for driving the virus and said mitigation efforts should continue.
Birx ended the call on a hopeful note.
“We are watching each county, each city across the United States very carefully and are providing the best advice we have based on models … showing that these mitigation efforts are working,” she said.
