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 August 19, 2022

Off to a Great Start

It’s back to school time again, and parents and caregivers across the country are concerned about keeping their kids safe in the changing COVID-19 landscape. Last week CDC released new COVID-19 guidance, including an update to recommendations for K-12 schools and Early Care and Education (ECE) programs. The new guidance helps schools protect students and staff, including people who are at increased risk.* Here are some ways to stay safe at school.

  • Stay home when you’re sick. Even if it isn’t COVID-19, staying home still lowers the risk of spreading infections to other people.
  • Get tested. Test immediately if you have COVID-19 symptoms. If you test positive, follow recommendations for isolation. If you were exposed to COVID-19 and do not have symptoms, wait at least 5 full days after your exposure before testing. If you test negative—and you used an at-home test—see FDA instructions on repeat testing.
  • Mask up. Staff and students should wear masks indoors if their COVID-19 Community Level is high, if they have been exposed to COVID-19, or if they are returning from isolation. To check your COVID-19 Community Level, visit COVID Data Tracker.
  • Practice good hand hygiene and respiratory etiquette. Students should learn proper handwashing and to cover coughs and sneezes.
  • Optimize ventilation, especially in places with high COVID-19 Community Levels. Effective ventilation and air filtration are important parts of COVID-19 prevention.

Schools are safer when students and staff are up to date on their vaccinations. All children ages 6 months and older are eligible for COVID-19 vaccines, and children 5 years and older are eligible for boosters. Children have been less affected by COVID-19 compared with adults, but they can get sick with COVID-19 and can spread it to others around them. Keeping all children healthy and safe is the key to getting this school year off to a great start.

*Some students might need additional protections in the classroom—including those who are immunocompromised, with complex medical conditions, or with certain disabilities that can put them at higher risk of severe outcomes from COVID-19. Learn more about actions you can take to protect yourself and others.

COVID-19 Community Levels

As of August 18, 2022, there are 1,091 (33.9%) counties, districts, or territories with a high COVID-19 Community Level, 1,324 (41.1%) counties with a medium Community Level, and 805 (25.0%) counties with a low Community Level. Compared with last week, this represents a moderate decrease (−5.7 percentage points) in the number of high-level counties, a marginal increase (+0.5 percentage points) in the number of medium-level counties, and a moderate increase (+5.2 percentage points) in the number of low-level counties. Overall, 49 out of 52 jurisdictions* had high- or medium-level counties this week. The District of Columbia, New Hampshire, and Nevada 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.

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

Reported Cases

As of August 17, 2022, the current 7-day moving average of daily new cases (95,652) decreased 9.9% compared with the previous 7-day moving average (106,116). A total of 93,124,238 COVID-19 cases have been reported in the United States as of August 17, 2022.

Variant Proportions

CDC Nowcast projections* for the week ending August 20, 2022, estimate that the combined national proportion of lineages designated as Omicron will continue to be 100% with the predominant Omicron lineage being BA.5, projected at 88.9% (95% PI 87.6-90.1%).

There are several lineages of Omicron and within each are multiple sublineages. The national proportion of BA.4.6 is projected to be 6.3% (95% PI 5.2-7.6%), BA.4 is projected to be 4.3% (95% PI 4.0-4.7%), and BA.2.12.1 is projected to be 0.5% (95% PI 0.4-0.5%). 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. Starting August 12, these projections use the most recent three weeks rather than the most recent two weeks of data. These data are now being updated on Fridays instead of Tuesdays. 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 652,811 historical cases reported retroactively, 11 were reported in the current week and none were reported in the prior week.

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 among Adults Ages ≥65 Years

CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that overall rates of COVID-19-associated hospitalizations have increased since the week ending April 2, 2022. Notably, rates among adults ages 65 years and older have seen a sharp increase, from 6.4 per 100,000 population on April 2, to 31.9 per 100,000 population on July 23. Rates of COVID-19-associated hospitalizations among adults aged ≥65 years have remained elevated for more than two months, ranging from 25.3 to 31.9 per 100,000 between May 14 and July 23.

COVID-NET: Hospitalization Rates by Vaccination Status among Adults Ages ≥50 Years 08-19-2022

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 1,000 testing sites across the country.

Currently, most of the country is reporting moderate to high SARS-CoV-2 levels in wastewater. About half of sites reporting wastewater data are currently seeing some of the highest levels for those sites since December 1, 2021. About half of sites are experiencing a decrease in SARS-CoV-2 levels, and about 40% 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.
