Summer Covid-19 wave continues to build across all regions

Covid-19 surges across all regions with wastewater and emergency department visits climbing. Children show highest ED visit rates, but seniors remain at greatest risk.

During summer months, this weekly respiratory illness report is available to paid subscribers only. Beginning in October with the onset of flu season, everyone gets the national overview for free, while paid subscribers receive bonus regional reports with state-by-state details to help you understand what's happening locally.

Respiratory Diseases

Influenza-like illness

Influenza remains very low nationally, with every state reporting minimal ILI activity. Wastewater is very low, and less than 1.2% of outpatient visits were for influenza-like illness. Activity continues to be roughly stable, neither increasing nor decreasing.

Looking across the age groups, the youngest cohort (aged 0-4 years) had a 3.40% outpatient ILI rate last week, followed by the 5-24 year-olds at 1.35%. All other age groups remain at <1%.

COVID-19

Activity is continuing to increase across the country. Wastewater concentration rose sharply in all four regions of the country (shown below). Emergency department visits are rising as well.

I am not seeing any signs of peaking yet, even in the early-hit states, so I expect activity to continue to rise in the weeks ahead.
