UPDATE
Given new evidence on the B.1.617.2 (Delta) variant, CDC has updated the guidance for fully vaccinated people. CDC recommends universal indoor masking for all teachers, staff, students, and visitors to K-12 schools, regardless of vaccination status. Children should return to full-time in-person learning in the fall with layered prevention strategies in place.
UPDATE
The White House announced that vaccines will be required for international travelers coming into the United States, with an effective date of November 8, 2021. For purposes of entry into the United States, vaccines accepted will include FDA approved or authorized and WHO Emergency Use Listing vaccines. More information is available here.

Interpretive Summary for September 30, 2022

The Update on “Up to Date”

Since CDC recommended the updated (bivalent) COVID-19 boosters earlier this month, 7.6 million eligible people in the United States have gotten one. Bivalent boosters help restore protection that might have gone down since your last dose—and they also give extra protection for you and those around you against all lineages of the Omicron variant. Both Moderna and Pfizer offer bivalent boosters.

The introduction of the new boosters has caused some changes in vaccine recommendations, which are based on your age, the vaccine you first received, and time since your last dose. You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent booster dose recommended for you by CDC. Here’s the breakdown:

  • People ages 6 months through 4 years should get all COVID-19 primary series doses.
  • People ages 5 years and older should get all primary series doses, and the booster dose recommended for them by CDC.
    • People ages 5 to 11 years are currently recommended to get the original (monovalent) booster.
    • People ages 12 years and older are recommended to receive the updated Pfizer or Moderna bivalent booster.
      • This includes people who have received all primary series doses and people who have previously received one or more original boosters.
      • At this time, people ages 12 to 17 years can only receive the updated Pfizer bivalent booster.
  • People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.

The more people who stay up to date on their vaccinations, the better chance we have of avoiding a possible surge in COVID-19 illness later this fall and winter. Use this tool to determine when or if you (or your child) can get one or more COVID-19 boosters.

Note to Readers: CDC will not publish COVID Data Tracker Weekly Review on Friday, October 7, 2022. Publication will resume on Friday, October 14, 2022

What's New
  • COVID Data Tracker’s Vaccinations in the US page was updated to include bivalent booster dose data. Additionally, the “Vaccine Administration by Vaccine Type” and “Vaccine Distribution by Vaccine Type” charts were relabeled with “Pfizer/Moderna original” and “Pfizer/Moderna updated booster.”  

COVID-19 Community Levels*

As of September 29, 2022, there are 107 (3.3%) counties, districts, or territories with a high COVID-19 Community Level, 737 (22.9%) counties with a medium Community Level, and 2,373 (73.7%) counties with a low Community Level. Compared with last week, this represents a moderate decrease (−3.7 percentage points) in the number of high-level counties, a large decrease (-8.3 percentage points) in the number of medium-level counties, and a large increase (+12.0 percentage points) in the number of low-level counties. Overall, 45 out of 52 jurisdictions** had high- or medium-level counties this week. Arizona, the District of Columbia, Hawaii, Nevada, New Mexico, Rhode Island, and Utah are the only jurisdictions to have all counties at low Community Levels.

To check your COVID-19 Community Level, visit COVID Data Tracker. To learn which prevention measures are recommended based on your COVID-19 Community Level, visit COVID-19 Community Level and COVID-19 Prevention.

*CDC recommends use of COVID-19 Community Levels to determine the impact of COVID-19 on communities and to take action. CDC also provides Community Transmission Levels to describe the amount of COVID-19 spread within each county. Healthcare facilities use Community Transmission Levels to determine infection control interventions.

**Includes the 50 states, the District of Columbia, and U.S. territories.

Reported Cases

As of September 28, 2022, the current 7-day moving average of daily new cases (47,112) decreased 13.1% compared with the previous 7-day moving average (54,202). A total of 96,052,716 COVID-19 cases have been reported in the United States as of September 28, 2022.

Variant Proportions

CDC Nowcast projections* for the week ending October 1, 2022, estimate that the combined national proportion of lineages designated as Omicron will continue to be 100%. There are five sublineages designated as Omicron: BA.5, BA.4.6, BF.7, BA.2.75, and BA.4. The predominant Omicron lineage is BA.5, projected to be 81.3% (95% PI 79.6-83.0%).

The national proportion of BA.4.6 is projected to be 12.8% (95% PI 11.5-14.1%), BF.7 is projected to be 3.4% (95% PI 2.6-4.4%), BA.2.75 is projected to be 1.4% (95% PI 1.1-1.9%), and BA.4 is projected to be 1.1% (95% PI 1.0-1.2%. 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 670,655 historical cases reported retroactively, 11,753 were reported in the current week and none were reported in the prior week.

Daily Admissions of Patients with confirmed COVID-19 - 7 day moving average

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 among Adults 85 Years and Older

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that COVID-19-associated hospitalizations are highest among adults ages 85 years and older. However, rates (per 100,000 population) have decreased by 25% over the past month, from 83.1 for the week ending August 6, 2022, to 62.0 for the week ending September 10, 2022.

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.

Wastewater Surveillance

COVID Data Tracker’s Wastewater Surveillance tab tracks levels, changes, and detections of SARS-CoV-2* viral RNA in wastewater at over 1,250 testing sites across the country. Currently, most of the country is reporting moderate to high SARS-CoV-2 levels in wastewater. About 16% of sites reporting wastewater data are currently seeing some of the highest levels for those sites since December 1, 2021. About 53% of sites are experiencing a decrease in SARS-CoV-2 levels, and about 41% 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.
