People’s CDC COVID19 Weather Report


The Weather: While transmission levels dropped slightly from last week, 92.64% of the population is living in areas with substantial or higher transmission and the percent living in counties with substantial transmission has increased, which is not a good trend.

Due to incomplete data reporting from Hawaii and Mississippi, as well as a backlog of cases now being reported from Arizona and several counties in Georgia, determining an overall national trend in transmission levels is challenging. 

Map and table show COVID transmission levels by US county as of Feb 27, 2023 based on the number of COVID cases per 100,000 population and percent positivity in the past 7 days. Low to Moderate levels are pale yellow, Substantial is orange, High is red, Very High is brown, and Extremely High is black. Eastern, southern, Midwest, and parts of the Southwest are almost all red, while the northwest is pale yellow and orange. Text in the bottom right: 92.64 percent of the US population lives in an area with substantial or higher transmission. Transmission Level table shows 0.86 percent of counties (1.44 percent by population) as Extremely High, 1.59 percent of the counties (0.38 percent by population) as Very High, 51.62 percent of counties (52.44 percent by population) as High, 24.38 percent of counties (38.38 percent by population) as Substantial, and 21.55 percent of counties (7.37 percent by population) as Low to Moderate.

Wins: California Nurses Association is relieved the CA Department of Public Health says that they are not lifting universal masking in healthcare–but we’ve got to keep the pressure on to make sure that they don’t rescind it later!

Keep up the pressure to #KeepMasksInHealthcare by joining the Senior and Disability Action-led campaign! It’s already working to keep CA DPH on their toes, so keep up the heat!

The current action hotspot in California is San Francisco, where they’re attempting to defy state-wide mask policy. Please join SDA in keeping up the pressure so we can minimize the risk of catching COVID in hospitals. 

On Variants: This week, Kraken (XBB.1.5) makes up 85% of cases, surpassing the 80.2% of cases reported in last week’s Weather Report.

A stacked bar chart with weeks on the x-axis shows weeks from Nov 20, 2022 to Feb 25, 2023 and y-axis as percentage of viral lineages among infections. The recent 3 weeks are labeled as Nowcast projections.  XBB.1.5 (dark purple) continues to increase, making up about 85.0 percent of current week infections. BQ.1.1 (teal) continues to decrease in recent weeks but remains the second most prevalent lineage currently around 9.4 percent. BQ.1 (dark teal) is now about half as prevalent as BQ.1.1 but remains visibly labeled at 2.6 percent. BA.5 (light teal), which in October was the dominant lineage, is now down to nearly zero visibility - joined by XBB (periwinkle purple) and a handful of other colors in the week ending Feb 25, 2023.

Kraken’s rise and spread has now become more complete across the country, popping-up in more than three-quarters of all cases in all regions except the Northwest.

Even in the Northwest, Kraken currently accounts for more than half of all cases. COVID protections are more important than ever.

Regional difference map of the US with 10 regions each depicted as shades of gray. In general, the numbers start in the Northeast and increase as they move south and then westward. Title reads “Nowcast Estimates for 2/19/2023 to 2/25/2023 by HHS Region.” Each region has a colored pie chart showing variant proportions. Legend at bottom right reads “Regional proportions from specimens collected the week ending 2/25/2023.” XBB1.5 (dark purple) makes up about 97 percent of the pie in regions 1 and 2, and 93% in 3 (Northeast & Mid-Atlantic). The proportion of XBB1.5 is lower moving westward, with ranges from about 66 to 86 percent across the remainder of the country. Bottom text reads: “Updated February 24, 2023” and  “Lineages called using pangolin v4.2, pangolin-data v1.18 and user v.0.6.1.”

Vaccination continues to be the best way to protect yourself from negative health outcomes from COVID infection. For example, a study has shown that vaccinated people who do get COVID tend to have fewer heart attacks and other cardiovascular issues.

It is critical to get vaccinated to lessen the chance of getting Long COVID and severe disease. While infection appears to confer protection from reinfection, according to a new meta-analysis, avoiding infection confers the best health outcome.

This meta-analysis also underscores the importance of on-going protective measures like masking and clean indoor air in addition to vaccines, as protection from reinfection drops dramatically over time, down to ~20-40% after 40 weeks.

This is why it is excellent news that even a small 10% increase in masking rates in schools has been shown to result in a large 50% decrease in detection of COVID in wastewater – masks continue to work to reduce transmission!

Wastewater Monitoring: Although wastewater levels appear to be decreasing across the country, it should be noted that this rate of decrease is leveling off in the Northeast, signaling that this trend may be temporary. 

The rise in wastewater levels in January in the Northeast and South was recently followed by a rise in the West and Midwest as the Kraken spread westward. This indicates that any slowdown in the decrease in the Northeast could signal a similar leveling off in other regions soon.

Top title reads, “Wastewater: Effective SARS-Cov-2 virus concentration (copies/mL of sewage)” and bottom title reads, “Source: Wastewater data from Biobot Analytics, Inc.” Line graph shows the levels of COVID detected in wastewater by US region, each region with a different color trend line. The y-axis shows copies per mL of sewage and the x-axis shows time between January 11, 2023 to February 22, 2023. A legend map of the US in the center shows the West region as green, South as pink, Midwest as purple, and Northeast as orange. There is a box on the right of the map that indicates the absolute number of copies/mL per region. Northeast (orange) has the highest amount of copies/mL, decreasing from 1,634 copies on January 4 to 693 on February 22, and appears to be leveling off at that date. As of February 22, there are 614 copies/mL in the Midwest (purple), 478 copies/mL in the South (pink), and 489 copies/mL in the West (green).

Hospitalizations: Hospitalizations for confirmed COVID cases continue at high levels, with rates nationally either declining at very slow rates, or flatlining depending on age group. Rates continue to be highest for those ages 70 and older.

Image of line graphs titled “New Admissions of Patients with Confirmed COVID-19” from August 1 2020 to February 22 2023. A line graph showing hospitalizations for all ages is on the left, and broken down by age group on the right. The y-axis is labeled new admissions per 100,000 people and range from 0 to 7 for all ages, and 0 to 20 by age group. The x-axis is time from August 1 2020 to February 22 2023. For all ages, the biggest peak is in January 2022, and another peak most recently occurred in early January 2023, and is currently downtrending with the most recent rate of 1.04 per 100,000 people. By age group, all ages individually peak in August and January of each year. 70+ (red) is the highest over the entire graph, followed by 65-69, and then progressively decreasing by decade, with the last 2 groups being 0-17 years and 18-29 years. In the last month, all ages are slightly decreasing. Age 70+ admissions are at about 5.1 per 100,000. The rest are under 2. Source: CDC

However, it appears there’s a slight increase in COVID hospitalizations for the Midwest (Region 5, 7, and 8) and West (Region 9), hinting that the aforementioned flatlining may become a rise in the near future.

Deaths: The week of February 25, at least 2,407 people died of COVID nationally. At least 1,115,637 people have died from COVID in the US in this continuing national tragedy.

This is especially tragic for our prison populations. The first comprehensive study on prison deaths shows a 50% rise in deaths in prisons in most states in 2020, mostly due to poor access to medical care during a time of rapid COVID spread in prisons.

Long COVID: It turns out that even our bones might be at the mercy of Long COVID, as researchers have recently discovered immune system-related and other changes in skeletal muscles of patients with Long COVID-induced fatigue.

It’s issues like these that result in increased unemployment nationally. Increasing evidence shows that such Long COVID effects negatively impact one’s ability to work, resulting in those with Long COVID being more likely to be unemployed.

Forecast: Negative mental health is also a result of COVID exposure. A recent study shows those who were pregnant or new parents who were exposed to COVID or living in countries with more COVID deaths in 2020 had higher symptoms of anxiety and depression. 

Proper protective measures generally improved mental health outcomes amongst pregnant people, as these increased feelings of protectiveness against COVID.

These studies and outcomes are critical for public health moving forward given the dramatic uncertainty caused by unmitigated COVID spread today.

Take Action: Read and share this brief guide for inclusive gatherings put together by Strategies for High Impact and the What Would a Doula Do Collective. Call for solidarity with the disabled community and make each gathering more equitable than the last!

Join the Massachusetts Coalition for Health Equity to demand the Department of Public Health keep masks in healthcare! Let’s show them that we will NOT accept living in a country where we catch COVID in the hospital!

Please join the National Nurses United in demanding the Office of Information and Regulatory Affairs finish reviewing OSHA standards to protect nurses that treat you when you go to the hospital so that they don’t themselves catch COVID.
