IL Among States Seeing Summer COVID Surge, Wastewater Data Shows

CHICAGO — Much of the country, including Illinois, is experiencing a summer bump in COVID-19 cases, according to updated wastewater surveillance data from the Centers for Disease Control and Prevention.

As of Friday, there were 27 states reporting “very high” levels of wastewater viral activity, while Illinois and 16 other states reported “high” levels.

The wastewater viral activity level in Illinois remains lower than the average in the Midwest, which in turn is lower than the national average, according to the CDC.

The “very high” level is the highest used by the agency to quantify viral activity. Other states in that category are California, Oregon, Washington, Idaho, Utah, Wyoming, Colorado, New Mexico, Texas, Oklahoma, Kansas, Minnesota, Missouri, Arkansas, Louisiana, Mississippi, Tennessee, Alabama, Florida, South Carolina, North Carolina, Virginia, West Virginia, Maryland, New Hampshire, Maine and Alaska.

The lowest level reported among states is “moderate,” and no states reported “low” or “minimal” levels of viral activity in wastewater. In July, only seven states reported “very high” levels of viral activity in wastewater and 19 reported “high” levels.

The CDC reported that 1.6 percent of all deaths in Illinois for the week ending Aug. 3 were due to COVID-19, marking an increase of 60 percent over the prior week. Meanwhile, just 1.9 percent of emergency room visits were attributable to the coronavirus.

Nationwide, COVID-19 fell to the 10th leading cause of death in the U.S. in 2023, down from fourth the prior year, according to the CDC.

With the current spike in COVID infections, “this is probably going to end up becoming the largest summer wave we’ve had,” Dr. Ashish Jha, dean of the Brown University School of Public Health and former White House COVID-19 response coordinator, told NBC News.

“It’s still not as big as the winter waves, but it is starting to get close,” Jha said, adding that he expects the wave to peak in the next few weeks.

The wastewater surveillance data, though limited, corresponds with a 13-week surge in positive COVID tests reported to the CDC — now more than 17 percent, up from 0.3 percent in early May. Hospitalizations are ticking up as well, with a rate of 3.3 percent, as of July 20, up from the low rate of 1.1 percent on April 20, the lowest hospitalization rate of the 2023-24 COVID season.

The region with the highest rates of COVID-19 positive tests includes Texas, Oklahoma, New Mexico, Louisiana and Arkansas, with a positive test rate of 24 percent for the week ending Aug. 3.

The CDC recommends that everyone over 6 months get updated COVID-19 vaccines when they become available this fall, regardless of whether the person has been previously vaccinated. The Food and Drug Administration recommends that pharmaceutical companies formulate vaccines to protect against the KP.2 strain, known as FLiRT variant, which is responsible for about 6 percent of positive COVID cases nationwide.

The World Health Organization declared an end to the COVID-19 public health emergency more than a year ago, but experts say the only way to hold the coronavirus at bay is for people to get vaccinated.

“Population immunity has moved us out of the pandemic,” said Dr. Manisha Patel, chief medical officer for the Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases. “Now the goal is to make sure we keep that immunity up because it does wane. And the way we keep it up is through vaccination. That is the safest way to keep our country healthy.”

Although it appears illnesses associated with FLiRT aren’t as serious as those caused by other variants, some symptoms set it apart. They include:

• Sore throat
• Cough
• Fatigue
• Congestion
• Runny nose
• Fever or chills
• Headache
• Muscle aches
• Loss of sense of taste or smell
• Diarrhea

Avoiding crowded indoor areas, wearing a mask, and avoiding those who are sick with COVID are all ways to prevent catching the new FLiRT variant, health officials have said.
