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 December 02, 2022

An Effective Boost

New data recently released by CDC highlight the importance of an updated (bivalent) booster for everyone ages 5 years and older. The report found that an updated (bivalent) booster provides additional protection from COVID-19 illness in people who previously received two or more doses of an original (monovalent) mRNA vaccine. Getting the updated (bivalent) booster restored protection that had decreased over time since receiving the last vaccine dose.

Additionally, CDC’s COVID Data Tracker now includes early data showing that people ages 12 years and older who got an updated (bivalent) booster were 15 times less likely to die from COVID-19 compared with people who were not vaccinated. CDC will continue to evaluate how well the updated (bivalent) booster is performing and will provide that information as it becomes available.

COVID-19 spread has increased the last two winters, so stay up to date on COVID-19 vaccines this holiday season to prevent serious illness and death. The updated (bivalent) booster protects against the original strain of the virus and the currently circulating Omicron BA.4 and BA.5-related lineages and sublineages. Getting one updated (bivalent) booster is recommended for all people ages 5 years and older if it has been at least two months since their last COVID-19 dose (either primary series or original monovalent booster).

What's New

COVID-19 Community Levels*

As of December 1, 2022, there are 182 (5.7%) counties, districts, or territories with a high COVID-19 Community Level, 799 (24.8%) counties with a medium Community Level, and 2,234 (69.5%) counties with a low Community Level. Compared with last week, this represents an increase (+2.0 percentage points) in the number of high-level counties, an increase (+6.5 percentage points) in the number of medium-level counties, and a decrease (-8.5 percentage points) in the number of low-level counties. Overall, 46 out of 52 jurisdictions** had high- or medium-level counties this week. District of Columbia, Hawaii, New Hampshire, Rhode Island, South Carolina, and Vermont 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 Puerto Rico.

Reported Cases

As of November 30, 2022, the current 7-day average of weekly new cases (43,300) decreased 1.2% compared with the previous 7-day average (43,837). A total of 98,777,220 COVID-19 cases have been reported in the United States as of November 30, 2022.

Variant Proportions

CDC Nowcast projections* for the week ending December 3, 2022, estimate the proportion of lineages designated as Omicron with estimates above 1%: BA.5—and four of its sublineages (BQ.1, BQ.1.1, BF.7, and BA.5.2.6)—BA.4.6,and XBB. XBB is a recombinant of two BA.2 sublineages.

The two predominant Omicron lineages are BQ.1.1, projected to be 31.9% (95% PI 29.7-34.3%) and BQ.1, projected to be 30.9% (95% PI 28.7-33.3%) nationally. Additionally, COVID Data Tracker shows XBB; it is projected to be 5.5% (95% PI 2.7-10.6%).

*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 weekly new cases and 7-day average calculations until they are incorporated into the dataset for the applicable date. No historical cases reported at this time.

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: Recent Trends in Hospitalization Rates among Adults and Children (All Ages)

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that COVID-19-associated hospitalizations have remained relatively stable for more than two months. Hospitalization rates among people of all ages declined from a recent peak of 9.6 per 100,000 population for the week ending July 30, 2022, and have remained below 6.5 per 100,000 population since the week ending September 17, 2022.

Weekly Rates of COVID-19-Associated Hospitalizations among Adults and Children (All Ages)

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 1,200 testing sites across the country.

Currently, about 50% of the country is reporting moderate to high SARS-CoV-2 levels in wastewater. About 22% of sites reporting wastewater data are currently seeing some of the highest levels for those sites since December 1, 2021. About 34% of sites are experiencing a decrease in SARS-CoV-2 levels, and about 58% are reporting an increase.
