Fall Boost
Interpretive Summary for September 9, 2022
Fall Boost
On September 1, CDC recommended that everyone ages 12 years and older in the United States receive an updated COVID-19 booster before a possible surge in COVID-19 illnesses later this fall and winter. Like the original boosters, the updated doses help restore protection that might have gone down since your last dose—but they also give extra protection for yourself and those around you against the most recent variants.
The updated booster is a bivalent vaccine because it targets two Omicron subvariants: BA.4 and BA.5. These newest subvariants are more contagious and able to evade protection that your body might have against earlier subvariants. Data suggest that the updated boosters also increase our immune response, which will help protect us against future variants.
Being up to date with COVID-19 vaccines is the best way to protect against severe illness, hospitalization, and death associated with COVID-19. Everyone who is eligible―including those who are moderately to severely immunocompromised―is recommended to receive one dose of the updated bivalent booster at least two months after their last dose (either the final primary series or the last booster). The Moderna COVID-19 Vaccine, BivalentExternal is authorized for use as single booster dose in people ages 18 years and older. The Pfizer-BioNTech COVID-19 Vaccine, BivalentExternal is authorized for use as a single booster dose in people ages 12 years and older. To find a vaccine provider near you, visit vaccines.gov.
Note to readers: Flu season is approaching. CDC recommends getting both a COVID-19 vaccine and a flu shot at the same visit. If you haven’t gotten your currently recommended dose of COVID-19 vaccine, get it as soon as you can, along with your flu vaccine.

COVID-19 Community Levels
As of September 8, 2022, there are 555 (17.2%) counties, districts, or territories with a high COVID-19 Community Level, 1,278 (39.7%) counties with a medium Community Level, and 1,387 (43.1%) counties with a low Community Level. Compared with last week, this represents a large decrease (−8.6 percentage points) in the number of high-level counties, a marginal decrease (-2.3 percentage points) in the number of medium-level counties, and a large increase (+10.2 percentage points) in the number of low-level counties. Overall, 47 out of 52 jurisdictions* had high- or medium-level counties this week. The District of Columbia, Massachusetts, Nevada, Rhode Island, and Washington are the only jurisdictions to have all counties at low Community Levels.

Reported Cases
As of September 7, 2022, the current 7-day moving average of daily new cases (70,488) decreased 18.8% compared with the previous 7-day moving average (86,853). A total of 94,888,931 COVID-19 cases have been reported in the United States as of September 7, 2022.
Variant Proportions
CDC Nowcast projections* for the week ending September 10, 2022, estimate that the combined national proportion of lineages designated as Omicron will continue to be 100% with the predominant Omicron lineage being BA.5, projected at 87.5% (95% PI 86.2-88.7%).
There are several lineages of Omicron and within each are multiple sublineages. The national proportion of BA.4.6 is projected to be 9.2% (95% PI 8.1-10.4%), BA.4 is projected to be 2.2% (95% PI 2.1-2.4%), BA.2 is projected to be 1.0% (95% PI 0.6-1.7%), and BA.2.12.1 is projected to be 0.1% (95% PI 0.1-0.1%). 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 658,918 historical cases reported retroactively, none were reported in the current week and 16 were reported in the prior week.

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.
COVID-NET: Hospitalization Rates by Vaccination Status among Adults Ages ≥65 Years
CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that pediatric rates of COVID-19-associated hospitalizations remain highest among children younger than 6 months old. For the week ending August 20, 2022, hospitalization rates among children younger than 6 months old are 17.8 per 100,000 population, compared with 3.7, 0.9, and 1.1 per 100,000 population for children ages 6 months–4 years, 5–11 years and 12–17 years, respectively.
Monthly Rates of COVID-19-Associated Hospitalization among Children Ages 0–17 Years
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.
Deaths
The current 7-day moving average of new deaths (314) has decreased 28.1% compared with the previous 7-day moving average (437). As of September 7, 2022, a total of 1,043,921 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 13.2%. The 7-day average number of tests reported for August 26–September 1, 2022, was 466,849, down 9.1% from 513,596 for the prior 7 days.

Wastewater Surveillance
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 27% of sites reporting wastewater data are currently seeing some of the highest levels for those sites since December 1, 2021. About 56% of sites are experiencing a decrease in SARS-CoV-2 levels, and about 38% 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.
