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.

Interpretive Summary for August 6, 2021

We Were on a Break!

Most U.S. states and jurisdictions are experiencing substantial or high levels of community transmission fueled by the spread of the highly contagious B.1.617.2 (Delta) variant. COVID-19 cases, hospitalizations, and deaths continue to increase, especially in communities with lower vaccination coverage. While the number of people getting vaccinated also continues to increase, many people remain unsure about getting vaccinated, and others do not plan to do so.

On July 27, 2021, CDC announced updated Guidance for COVID-19 Prevention Strategies based on emerging evidence of the B.1.617.2 (Delta) variant. CDC recommends that all people, regardless of vaccination status, wear masks in public indoor settings in areas of substantial or high transmission. A new CDC study supports previous findings that B.1.617.2 (Delta) is highly contagious, and is contributing to an increase in cases, including those with severe outcomes and those due to vaccine breakthrough infections. While vaccinated people can still develop COVID-19, they are far less likely to get severely sick or die than people who are unvaccinated.

United States Levels of Community Transmission

United States Levels of Community Transmission

Vaccination is the best tool we have for protecting ourselves and our loved ones against COVID-19. The COVID-19 vaccines authorized for use in the United States continue to protect against severe illness, hospitalizations, and death. To find a vaccine provider near you, visit Vaccines.gov or your state or local public health department website. If you or someone you know is hesitant about COVID-19 vaccination, CDC has information and answers to frequently asked questions to help make informed decisions.

Note to readers: The latest county-level data for each state (including cases, deaths and level of community transmission) can be downloaded from COVID Data Tracker’s County View page by following the steps below:

Reported Cases

The current 7-day moving average of daily new cases (89,977) increased 33.7% compared with the previous 7-day moving average (67,274). The current 7-day moving average is 30.9% higher compared to the peak observed on July 20, 2020 (68,717). The current 7-day moving average is 64.6% lower than the peak observed on January 10, 2021 (254,060) and is 682.9% higher than the lowest value observed on June 19, 2021 (11,493). A total of 35,392,284 COVID-19 cases have been reported as of August 4.

SARS-CoV-2 Variants

Multiple variants of the virus that causes COVID-19 are circulating globally, including within the United States. Currently, four variants are classified as a variant of concern (VOC). Nowcast estimates* of SARS-CoV-2 cases caused by these VOCs for the two weeks ending July 31 are summarized here. Nationally, the combined proportion of cases attributed to Delta (B.1.617.2, AY.1, AY.2, AY.3) is predicted to increase to 93%; Alpha (B.1.1.7) proportion is predicted to decrease to 2.9%; Gamma (P.1) proportion is predicted to decrease to 1.3%; and Beta (B.1.351) is predicted to be less than 0.1%. Nowcast estimates predict that Delta (B.1.617.2, AY.1, AY.2, and AY.3) will continue to be the predominant lineage circulating in all 10 HHS regions. Alpha (B.1.1.7) is predicted to be less than 7% in all HHS regions. Gamma (P.1) is predicted to be 3.1% or less in all HHS regions; and Beta (B.1.351) is predicted to be less than 0.2% 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 Variant Proportions page.

Testing

The percentage of COVID-19 NAATs (nucleic acid amplification tests) that are positive (percent positivity) has increased from the previous week. The 7-day average of percent positivity from tests is now 9.5%. The 7-day average number of tests reported for Jul 23 – Jul 29 was 816,672 up 15.4% from 707,631 for the prior 7 days.

Vaccinations

The U.S. COVID-19 Vaccination Program began December 14, 2020. As of August 5, 348.9 million vaccine doses have been administered. Overall, about 193.2 million people, or 58.2% of the total U.S. population, have received at least one dose of vaccine. About 165.6 million people, or 49.9% of the total U.S. population, have been fully vaccinated.* As of August 5, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 699,261, a 13.63% increase from the previous week.

CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of August 5, 90.2% of people ages 65 or older have received at least one dose of vaccine and 80.3% are fully vaccinated. Over two-thirds (70.4%) of people ages 18 or older have received at least one dose of vaccine and 60.8% are fully vaccinated. For people ages 12 or older, 68.1% have received at least one dose of vaccine and 58.4% 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 CMS Provider of Services file, which is used to identify the cohort of included hospitals.

COVID-NET: Trends in Hospitalizations in Children Ages 4 Years and Younger

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that hospitalization rates are increasing, including rates in children. Compared to June 26, 2021, weekly rates in children ages 4 years and younger for the week ending July 17, 2021 have tripled from 0.2 to 0.6 per 100,000 population. While rates are higher in adults, children—including very young children—are also at risk for COVID-19-associated hospitalizations. Unlike adults, children younger than 12 years of age are not yet eligible for any of the available COVID-19 vaccines.

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.
