Interpretive Summary for September 23, 2022
The COVID-19 pandemic has had a major impact on all our lives. For many, this has meant delayed medical care, sleepless nights, extra screen time, and isolation from friends and family. As the days get shorter and cooler and the seasons change, try these strategies to take care of yourself and maintain a healthy lifestyle.
Remember ― prevention is the best medicine. Regular checkups provide the opportunity to prevent, screen for, and manage chronic conditions, and get routine vaccinations. This fall, get your COVID-19 booster and flu shot. Both COVID-19 and flu vaccines have been shown to reduce illness, hospitalizations, and deaths. You can get them both at the same time if you are eligible and the timing works. Find a vaccine provider near you.
As of September 22, 2022, there are 226 (7.0%) counties, districts, or territories with a high COVID-19 Community Level, 1,005 (31.2%) counties with a medium Community Level, and 1,986 (61.7%) counties with a low Community Level. Compared with last week, this represents a large decrease (−6.3 percentage points) in the number of high-level counties, a moderate decrease (-4.7 percentage points) in the number of medium-level counties, and a large increase (+11.0 percentage points) in the number of low-level counties. Overall, 46 out of 52 jurisdictions* had high- or medium-level counties this week. Arizona, the District of Columbia, Hawaii, New Mexico, Rhode Island, and Utah are the only jurisdictions to have all counties at low Community Levels.

As of September 21, 2022, the current 7-day moving average of daily new cases (54,186) decreased 10.6% compared with the previous 7-day moving average (60,593). A total of 95,700,347 COVID-19 cases have been reported in the United States as of September 21, 2022.
Variant Proportions
CDC Nowcast projections* for the week ending September 24, 2022, estimate that the combined national proportion of lineages designated as Omicron will continue to be 100%. There are five lineages designated as Omicron: BA.5, BA.4.6, BA.4, BF.7, and BA.2.75. The predominant Omicron lineage is BA.5, projected at 83.1% (95% PI 81.3-84.7%).
The national proportion of BA.4.6 is projected to be 11.9% (95% PI 10.6-13.4%), BF.7 is projected to be 2.3% (95% PI 1.7-3.0%), BA.4 is projected to be 1.4% (95% PI 1.3-1.5%), and BA.2.75 is projected to be 1.4% (95% PI 0.9-2.0%). See COVID Data Tracker for current data.

*CDC uses Nowcast projections to predict current variant proportions circulating in the United States. The median time from specimen collection to sequence data reporting is about 3 weeks. As a result, weighted estimates for the most recent few weeks may be unstable or unavailable. View Nowcast estimates on CDC’s COVID Data Tracker website on the Variant Proportions page.
**Historical cases are excluded from daily new cases and 7-day average calculations until they are incorporated into the dataset for the applicable date. Of 658,910 historical cases reported retroactively, none were reported in the current week and 8 were reported in the prior week.

As of September 21, 2022, 616.2 million vaccine doses have been administered in the United States. Overall, about 263.8 million people, or 79.5% of the total U.S. population, have received at least one dose of vaccine. About 225.0 million people, or 67.8% of the total U.S. population, have completed a primary series.*

Of those who have completed a primary series, about 109.6 million people have received a booster dose,* and 4.4 million people have received an updated (bivalent) booster dose. But 49.9% of the total booster-eligible population has not yet received a booster dose. Booster dose eligibility varies by age and health condition. Learn more about who is eligible.

Daily Trends in Number of New COVID-19 Hospital Admissions in the United States
New admissions are pulled from a 10 am EDT snapshot of the HHS Unified Hospital Data – Analytic Dataset. Due to potential reporting delays, data from the most recent 7 days, as noted in the figure above with the grey bar, should be interpreted with caution. Small shifts in historic data may also occur due to changes in the Centers for Medicare & Medicaid Services (CMS) Provider of Services file, which is used to identify the cohort of included hospitals.
CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that COVID-19-associated hospitalizations continue to affect adults ages 65 years and older. Since early April 2022, more than 50% of all COVID-19-associated hospitalizations occurring every week are among adults ages 65 years and older. Before April 2022, adults ages 65 years and older had not comprised more than half of all COVID-19-associated hospitalizations since January 2021.
Trends in Hospitalizations among Adults 65 Years and Older

The Coronavirus Disease 2019 (COVID-19)-Associated Hospitalization Surveillance Network (COVID-NET) is an additional source for hospitalization data collected through a network of more than 250 acute-care hospitals in 14 states (representing ~10% of the U.S. population). Detailed data on patient demographics, including race/ethnicity, underlying medical conditions, medical interventions, and clinical outcomes, are collected using a standardized case reporting form.
The current 7-day moving average of new deaths (347) decreased 12.2% compared with the previous 7-day moving average (396). As of September 21, 2022, a total of 1,049,864 COVID-19 deaths have been reported in the United States.

The percentage of COVID-19 NAATs (nucleic acid amplification tests)* that are positive is decreasing in comparison to the previous week. The 7-day average of percent positivity from NAATs is now 10.7%. The 7-day average number of tests reported for September 9 – 15, 2022, was 412,967, down 5.3% from 435,920 for the prior 7 days.

COVID-19 NAAT Laboratory Test 7-day Percent Positivity by State/Territory
COVID Data Tracker’s Wastewater Surveillance tab tracks levels, changes, and detections of SARS-CoV-2* viral RNA in wastewater at over 1,000 testing sites across the country.
Currently, most of the country is reporting moderate to high SARS-CoV-2 levels in wastewater. About 18% of sites reporting wastewater data are currently seeing some of the highest levels for those sites since December 1, 2021. About 49% of sites are experiencing a decrease in SARS-CoV-2 levels, and about 44% are reporting an increase. It’s important to note that even a small increase when levels are low can appear like a dramatic increase in the percent change.
For more information on how to use wastewater data, visit CDC’s website.

SARS-CoV-2 Levels in Wastewater by Site

0% means levels are the lowest they have been at the site; 100% means levels are the highest they have been at the site.
