Nationally, 7% of diagnostic tests came back positive last week, up
from 5% the prior week, according to a Reuters analysis of data from
The COVID Tracking Project, a volunteer-run effort to track the
outbreak.
The World Health Organization considers a positivity rate above 5%
to be a cause for concern because it suggests there are more cases
in the community that have not yet been uncovered.
Arizona's positivity test rate was 24% last week, Florida's was 16%,
and Nevada, South Carolina and Texas's were all 15%, according to
the analysis.

Thirty-one states, mostly in the U.S. West and South, reported more
new cases of COVID-19 last week compared to the previous week, the
analysis found. Florida, Louisiana, Idaho and Washington state saw
new cases more than double over that period.
In response to the new infections, Louisiana and Washington state
have temporarily halted the reopening of their economies. Washington
also mandated wearing masks in public.
Florida ordered all bars and some beaches to close. Idaho was not
immediately available for comment.

Nationally, new COVID-19 cases have risen every week for four straight weeks.
While part of that increase can be attributed to a 9% expansion in testing,
health experts have also worried about states relaxing stay-at-home orders that
had been credited with curbing the outbreak.
State officials across the country report the same trend in the new cases:
People under 35 years old are going to bars, parties and social events without
masks, becoming infected, and then spreading the disease to others.
Cases continue to decline in Northeast states, but some Midwest states that had
new infections under control are seeing cases once again rise, including
Illinois, Michigan and Pennsylvania.
