Seven US states have detected very high levels of Covid in their wasterwater, according to estimates released Friday from the Centers for Disease Control and Prevention.

It means that levels have reached the agencys high category for the first time this summer. California, Nevada, Oregon, Texas, Arkansas, Florida, and Maryland were the states with the highest levels, according to CDC data.

"We are seeing patterns that are consistent with what we have observed over the last couple of years in the summer, where we have seen upticks in activity that have occurred around this time of year that are not quite as large as what we see during the winter peaks," Aron Hall, deputy director for science in the CDCs Coronavirus and Other Respiratory Viruses Division, told CBS News.

In the San Francisco Bay area, Covid levels are comparable to the most recent winter surge, the time of year when Covid cases typically hit their peak, according to separate data from Stanford Universitys WastewaterSCAN project.

The levels were higher than where they were this time last year and on average as high as we saw during the winter peak earlier this year, WastewaterSCANs Amanda Bidwell told KQED.

Meanwhile, 26 states and Washington DC, are seeing substantial increases in emergency room visits because of Covid. The national share of Covid ER patients is up 115 percent since last month, the highest level since February.

Nationwide, test positivity was at 11 percent for the week ending in July 6, up from 9 percent the previous week.

Over the past month, 70 percent of infections have been driven by the KP variants, which descend from the JN.1 strain, one of the so-called FLiRT variants, according to an Axios analysis of CDC data. The FLiRT strains are subvariants of Omicron, Yale Medicine reported.

The combination of record-breaking summer travel, and people congregating inside to avoid the heat, is likely further driving cases. Experts say that despite the summer surge, previous immunity may keep overall hospitalizations and deaths low compared to other spikes in case levels.

About 95 percent of the population currently have identifiable antibodies to omicron, specifically omicron variants, so thats a very good herd immunity and it keeps us from having high levels of hospitalization, according to Dr Aileen Marty, an infectious disease expert at Florida International Universitys Herbert Wertheim College of Medicine.

The immunity, however, is only about 45% effective at preventing mild and moderate disease for these new strains because of those mutations that these new strains have, she told the Miami Herald.
