Important update: Healthcare facilities
CDC has updated select ways to operate healthcare systems effectively in response to COVID-19 vaccination. Learn more
To maximize protection from the Delta variant and prevent possibly spreading it to others, get vaccinated as soon as you can and wear a mask indoors in public if you are in an area of substantial or high transmission.
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.
UPDATE
Travel requirements to enter the United States are changing, starting November 8, 2021. More information is available here.

Interpretive Summary for November 19, 2021

Protecting Our Future

COVID-19 tends to be milder in children compared with adults, but it can make children very sick and lead to hospitalization or even death. To further protect children, those ages 5 years and older are now eligible to get an age-appropriate dose of Pfizer-BioNTech COVID-19 vaccine. Vaccinating children is also a crucial step toward stopping the spread of the virus that causes COVID-19 and ending the pandemic.

This week CDC’s COVID Data Tracker shows that rates of COVID-19 hospitalizations remain high in children between the ages of 5 through 11 years. A recent studyexternal icon of more than 2,000 children under 18 years found that nearly 1 in 3 children hospitalized with COVID-19 were admitted to the intensive care unit or put on a ventilator. Although children with underlying medical conditions are at increased risk for more severe illness from COVID-19, almost half (45%) of the hospitalized children in this study had no known underlying medical conditions. These results show that children can be severely affected by COVID-19.

Widespread vaccination for COVID-19 remains a critical tool to best protect everyone, especially those at highest risk, from severe illness and death. CDC recommends everyone ages 5 years and older get a COVID-19 vaccine to help protect against COVID-19. Vaccinating children ages 5 years and older can help keep them in school and safely participate in sports, playdates, and other group activities. Vaccinating children can also help protect family members, including siblings who are not eligible for vaccination and family members who may be at increased risk of getting very sick if they are infected. COVID-19 vaccines for children ages 5 through 11 years are now available at pediatricians’ offices, pharmacies, Federally Qualified Health Centers, and more. To find a vaccination site near you, visit vaccines.gov; text your ZIP code to 438829 (GETVAX); or call 1-800-232-0233. If you have questions about COVID-19 vaccines in children, talk with your child’s pediatrician or healthcare provider.

Note to readers: In observance of the Thanksgiving holiday, CDC will not publish the COVID Data Tracker Weekly Review on Friday, November 26, 2021. The Weekly Review will resume publication on Friday, December 3, 2021.

Reported Cases

The current 7-day moving average of daily new cases (88,482) increased 16.1% compared with the previous 7-day moving average (76,223). A total of 47,352,367 COVID-19 cases have been reported as of November 17, 2021.

Currently, Delta is the only variant classified as a Variant of Concern (VOC) in the United States. Nowcast projections* for the week ending November 13, 2021, estimate the national and regional proportions of Delta to be greater than 99%. CDC continues to monitor variants and additional information may be provided in future editions based on current trends. For more information on variant proportions, visit COVID Data Tracker.

*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.

**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 335,974 historical cases reported retroactively, 16,290 were reported in the current week and 3,197 were reported in the prior week.

Vaccinations

The U.S. COVID-19 Vaccination Program began December 14, 2020. As of November 17, 2021, 444.8 million vaccine doses have been administered. Overall, about 228.2 million people, or 68.7% of the total U.S. population, have received at least one dose of vaccine. About 195.6 million people, or 58.9% of the total U.S. population, have been fully vaccinated.* About 31.5 million additional/booster doses in fully vaccinated people have been reported. As of November 17, 2021, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 1,471,757, a 11.8% increase from the previous week.

CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of November 17, 2021, 99.5% of people ages 65 years or older have received at least one dose of vaccine and 86.2% are fully vaccinated. More than three-quarters (81.7%) of people ages 18 years or older have received at least one dose of vaccine and 70.7% are fully vaccinated. For people ages 12 years or older, 79.8% have received at least one dose of vaccine and 68.9% are fully vaccinated. For people ages 5 years or older, 73.1% have received at least one dose of vaccine and 62.6% are fully vaccinated.

New admissions are pulled from a 10 am EST snapshot of the HHS Unified Hospital Timeseries 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 and Medicaid Services (CMS) Provider of Services file, which is used to identify the cohort of included hospitals.

COVID-NET: Children and Adolescents Hospitalized with COVID-19 with Underlying Conditions

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET)  shows that having certain medical conditions can increase the risk of becoming severely ill due to COVID-19. Data from March 1, 2020 through September 30, 2021, show that 54% of children and adolescents ages 17 years and younger with a laboratory-confirmed COVID-19-associated hospitalization have at least one underlying medical condition. Among children with a COVID-19-associated hospitalization, the most common underlying medical conditions include obesity (36%), asthma (15%), neurologic disease (14%), and cardiovascular disease (9%).

Information on risk factors for severe outcomes in COVID-19-associated hospitalizations among children can be found in a new report using COVID-NET data hereexternal icon.

Information on COVID-19 and underlying medical conditions can be found on CDC’s website.

Children and Adolescents Hospitalized with COVID-19 with Underlying Conditions

COVID-NET: Children and Adolescents Hospitalized with COVID-19 with Underlying Conditions 11-17-2021

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 standardized case reporting form.
