This includes several sublineages of delta, all of which are classified as variants of interest.
Together, they accounted for about 93.4% of cases during the last two weeks of July.

This number is even higher in certain parts of the country, including the region that includes Iowa, Kansas, Missouri, and Nebraska, where the delta variant accounts for more than 98% of the circulating virus.
These numbers have shown a rapid increase over the past two months.
In the two weeks ending May 22, for example, the prevalence of delta was estimated to be around 3%.
At the same time in May, another variant first identified in the UK, Alpha, or B.1,1.7, was dominant in the US, causing 69% of cases.
Now, the most recent estimates from the CDC put that variance at just under 3%.
