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.

Interpretive Summary for April 1, 2022

Added Protection

As the country emerges from the Omicron surge—and we experience low COVID-19 Community levels in most parts of the country—CDC has updated its COVID-19 vaccination guidance to give some people the option to get a second mRNA COVID-19 booster dose (Pfizer-BioNTech or Moderna). You can now receive a second booster dose if you:

COVID-19 vaccines continue to offer high levels of protection against severe disease, hospitalization, and death—especially for people who are boosted. During the recent Omicron surge, people who were boosted were 21 times less likely to die from COVID-19 compared to those who were unvaccinated, and 7 times less likely to be hospitalized. If you’re interested in getting a second booster, find a vaccine now.

*A recent CDC study found that adults who received the J&J/Janssen COVID-19 vaccine as both their primary dose and booster dose had lower levels of protection against COVID-19-associated hospitalizations, as well as emergency department and urgent care visits, during Omicron compared to adults who received an mRNA COVID-19 vaccine booster dose. As such, they may benefit from an mRNA COVID-19 vaccine booster dose and are now eligible to receive one.

What's New

COVID-19 Community Levels

On February 25, 2022, CDC updated the way it monitors COVID-19’s impact on our communities. Widespread availability of vaccines and testing, advances in treatments, and increasing levels of immunity in the population through vaccination or previous infection have moved the COVID-19 pandemic to a new phase. While we can’t prevent all cases of COVID-19, we can continue to limit the spread and protect those who are most at risk of severe illness.

Currently, there are 19 (0.59%) counties with a high COVID-19 Community Level, 146 (4.53%) counties with a medium Community Level, and 3,059 (94.88%) counties with a low Community Level. This represents a slight (−0.84%) decrease in the number of high-level counties, a moderate (−2.73%) decrease in the number of medium-level counties, and a corresponding (+3.57%) increase in the number of low-level counties. Twenty-seven (48.21%) of 56 jurisdictions had no high- or medium-level counties this week.

Reported Cases

As of March 30, 2022, the current 7-day moving average of daily new cases (25,732) decreased 3.0% compared with the previous 7-day moving average (26,518). A total of 79,904,464 COVID-19 cases have been reported in the United States as of March 30, 2022.

CDC Nowcast projections* for the week ending March 26, 2022, estimate the combined national proportion of lineages designated as Omicron to be 100%. There are five lineages designated as Omicron: B.1.1.529, BA.1, BA.1.1, BA.2, and BA.3. COVID Data Tracker shows the proportions of the B.1.1.529 lineage (includes BA.1 and BA.3), the BA.1.1** lineage, and the BA.2 lineage. The predominant Omicron lineage in the United States is BA.2. The national proportion of BA.2 is projected to be 54.9% (95% PI 50.8-59.1%). BA.1.1 is projected to be 40.4% (95% PI 36.4-44.5%) and B.1.1.529 (BA.1 and BA.3) is projected to be 4.7% (95% PI 3.9-5.7%). Omicron is predicted to be 100% in all HHS regions.

*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. CDC’s Nowcast is a data projection tool that helps fill this gap by generating timely estimates of variant proportions for variants that are circulating in the United States. View Nowcast estimates on CDC’s COVID Data Tracker website on the Variant Proportions page.

**For national data, the proportion of BA.1.1 is shown separately. For regional data, the proportion of BA.1.1 is also aggregated with B.1.1.529.

***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 504,648 historical cases reported retroactively, 18,610 were reported in the current week and 10,468 were reported in the prior week.

Vaccinations

The U.S. COVID-19 Vaccination Program began December 14, 2020. As of March 30, 2022, 560.4 million vaccine doses have been administered in the United States. Overall, about 255.4 million people, or 76.9% of the total U.S. population, have received at least one dose of vaccine. About 217.6 million people, or 65.5% of the total U.S. population, have been fully vaccinated.* About 97.5 million additional or booster doses have been reported in people who have been fully vaccinated; however, 49.8% of the total booster-eligible population has not yet received a booster dose. As of March 30, 2022, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 214,405, a 17.8% increase from the previous week.

CDC’s COVID Data Tracker displays vaccination trends by age group, race/ethnicity, and urban/rural status. To see trends by age group and race/ethnicity, visit the Vaccination Demographic Trends tab. To see trends by urban/rural status, visit the COVID-19 Vaccination Equity tab.

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 in Adults Ages ≥50 Years

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that rates of COVID-19-associated hospitalizations in February 2022 were higher in unvaccinated adults compared to adults who received a primary vaccination series plus a booster or additional dose of a COVID-19 vaccine. In February, among adults ages 50–64 years, the COVID-19-associated hospitalization rate among unvaccinated people was 7 times higher than among those who received a booster or additional dose. Among adults ages 65 years and older, the COVID-19-associated hospitalization rate among unvaccinated people was 9 times higher than among those who received a booster or additional dose.

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 with a standardized case reporting form.
