People’s CDC COVID-19 Weather Report

The Weather

This has been another dangerous week for public health.

The COVID.gov and COVIDtest.gov websites have been replaced with a new government website that features misinformation, propaganda, and a bizarre headline with a picture of Trump – more fitting for a Marvel villain than a US president.  

Several important CDC data sets remain intact, updated, and accessible, including data from the National Wastewater Surveillance System, COVID-NET hospitalizations, and others. But U.S. health data is still at risk or unavailable. For example, although the Behavioral Risk Factor Surveillance System website is live, some data has been removed, altered, and some has been restored, with a new label: “The CDC’s website is being modified to comply with President Trump’s Executive Orders.”

The delayed public meeting of the Advisory Committee on Immunization Practices (ACIP) was held in mid-April. This was ACIP’s first meeting with Robert F. Kennedy Jr. in charge of the Department of Health and Human Services. COVID experts discussed further reducing access to COVID-19 vaccines. 

We will continue to stay alert to this administration’s misinterpretation of scientific data. We are also concerned about potential data manipulations or omissions that have previously guided disease prevention efforts. 

The most recent CDC national wastewater map, last updated on April 17, 2025, shows data from March 30 to April 5 of this year.  Using the People’s CDC’s warm-toned version of the map, we can see that states like Connecticut, Kentucky, and South Carolina have high levels of COVID detected in wastewater. The state of Virginia also shows high levels, but these data are based on only six wastewater sites. Another four states have limited data, meaning that data from those states is based on less than 5% of the population. There is no data for North Dakota and the US Virgin Islands. The CDC has determined that national levels are “low,” with southern states still having the highest levels. 

A map of the United States color-coded in shades of orange and gray displaying SARS-CoV-2 Wastewater Viral Activity level from the dates March 30, 2025 - April 05, 2025 using CDC data updated on April 17, 2025. Deeper tones correlate to higher viral activity, and gray indicates “Insufficient” or “No Data.” Text above the map reads “High” levels in 4 states. There is no data for North Dakota and the U.S. Virgin Islands. At the bottom, the text reads “People’s CDC. Source: CDC.”

Wastewater trends indicate that nationally, the US is seeing improvement in wastewater levels. All regions in the US are seeing decreasing levels after reaching a peak in early January of 2025. We expect levels to rise again as the summer season approaches. And with CDC’s Current Epidemic Trends (Based on Rt) for States | CFA: Modeling and Forecasting | CDC, we see that COVID is likely increasing in Minnesota and Hawaii. 

Note, this modeling is with data from emergency department visits to estimate COVID transmission’s Rt , Ris an estimate of the average number of new infections caused by each infectious person. An Rgreater than 1.0 indicates that infections are growing, while an Rt less than 1.0 indicates that they’re declining. 

Wastewater COVID-19 National and Regional Trends

National Wastewater Levels are Slightly Declining

A line graph’s title reads, COVID-19 Wastewater Trends. April 5, 2024 through April 5, 2025. From data last updated April 17, 2025.” Wastewater Viral Activity Levels are indicated on the left-hand vertical axis, going from “Minimal” to “Very High”, and “Week Ending” across the horizontal axis, with date labels ranging from 5/4/24 to 4/5/25. A key at the bottom indicates line colors. National is black, Midwest is orange, South is purple, Northeast is light blue, and West is green. Levels are decreasing in all regions. The South remains in the Moderate zone, while all other regions are in the low zone. The decrease from the January peak until now was a much more gradual decrease than the other decrease noted last fall, when rates moved from high/very high in August 2024 to low in October 2024. Text at the bottom reads “People’s CDC. Source: CDC.”

As always, remember that the determination of the categories of “Very High,” “High,” “Moderate,” “Low,” and “Very Low” is independent of any relationship to community transmission. In other words, these categories do not necessarily reflect one’s risk of getting sick within each region at any given time. Wastewater data is best suited to reveal whether levels in your area are increasing or decreasing, or how levels in your area compare with other times throughout the pandemic. 

Wastewater monitoring is one of our most essential tools for monitoring communities’ health risks. We are concerned that funding may be vulnerable. While the need is high for even more wastewater monitoring, our current systems are threatened with funding cuts. We are closely watching California’s Wastewater Surveillance legislation, which could be a model for other states to better coordinate and protect this essential activity. It’s important to note that some wastewater sites have high and very high levels of activity. Please check the viral activity levels for your region by selecting your state here.

If county-level wastewater data is not available in your area, call your governor, state senators, and assembly to ask for it! The website ROADMAP for seeking government funding for enhancements related to wastewater surveillance has a list of government funding options for State, local, tribal, territorial governments, and non-profit organizations.  

Hospitalizations

Hospitalization data were also reviewed during the ACIP meeting. The data source, COVID-NET, is the CDC’s surveillance system for laboratory-confirmed COVID-19 hospitalizations. The current network covers approximately 34 million people or 10% of the U.S. population. 

The data show hospitalizations continue to peak in both winter and summer months, and there were fewer COVID hospitalizations this year compared to the 2023-2024 season. Yet for adults aged 65 years and older, hospitalizations for COVID were higher than hospitalizations for flu. 

Slide titled “Among adults ages greater than or equal to 65 years, rates of COVID-19-associated hospitalization during recent years remained higher than rates of influenza-associated hospitalization.” Below that title is a bar graph titled “Rates of influenza and COVID-19 associated hospitalizations among adults ages greater than or equal to 18 years, by age group and season.” Based on RESP-NET 2014-2025 data. The vertical axis represents hospitalization rates per 100,000 population, and the horizontal axis is divided into three age groups: 18-49, 50-64, and 65 years of age or older. Within each of these groups are flu seasons going from 2014-2015 to 2024-2025. For people ages 18-49, flu hospitalizations (marked with blue bars) remain well under 200 per 100,000. In 2019-2020, COVID-19 appears, with hospitalization rates more than double compared to the flu. The 2020-2021 and 2021-2022 season COVID-19 hospitalization rates in this group were nearing 400 per 100,000 population. And have since decreased with an equalization of both rates in 2023-2024. For the 50-64 year age group, flu hospitalization rates were previously in the 100-200 range, but when COVID-19 appears, the flu hospitalization rates decrease, returning to their baseline levels in 2023-2024. COVID-19 hospitalizations for this group appear in 2019-2020 at 200, then increase to nearly 800 in 2020-2021, drop to 600 in 2021-2022, then 200 in 2022-2023 and near 150 per 100,000 in 2023-2024. For those 65 or greater, flu hospitalization rates fluctuated between 200 and 900 per 100,000 population prior to COVID-19. Again, flu hospitalizations decreased in the first years of COVID-19 pandemic and have since returned to about 400 per 100,000 population. COVID-19 hospitalizations were greater than 400 in 2019-2020, increased to 1400 per 100,000 population in 2020-2021, increased again to 1600 in 2021-2022, decreased to 1000, then 800 over the next two years. In all three age group sections, 2024-2025 data is noted to be incomplete. Graphic source: CDC’s ACIP presentation slidesGraphic source: CDC’s ACIP presentation slides

Below, we give a brief summary of important takeaways from the slides from the CDC’s ACIP presentation about hospitalizations for COVID: 

  • Most adults hospitalized for COVID last year had not been vaccinated since 2022. – Slide #26
  • Most (nearly 75%) of adults at least 65 years of age who were hospitalized with COVID had not received the recommended COVID vaccine before they were hospitalized. – Slide #28:
  • Only 30% of nursing home residents had received a COVID vaccine that year.  – Slide #27

The People’s CDC believes these data show a high need to do better in protecting our elders with vaccine access, rather than reducing access to vaccines for others, as discussed at the ACIP meeting.

 Data are limited to hospitalizations where COVID-19 is a likely primary reason for admission.

Vaccines

People’s CDC supports the need for continuing universal, meaning easy and free, access to COVID vaccines. This summer, ACIP will vote on recommendations, and if vaccine access in the fall is reduced further, to vaccines only for those in the highest risk categories. 

For now, here are a few resources for parents from the People’s CDC: 

For everyone, especially seniors, you can still get COVID vaccines from pharmacies and clinics. Enter your zip code on the Vaccines.gov website to find out where.

Wins

Universities that are threatened with withdrawal of federal funding unless they comply with the Trump administration’s demands that interfere with free speech and scientific research should follow Harvard’s example and refuse to concede to those demands: “The university will not surrender its independence or relinquish its constitutional rights.” 

After three years of talks, a historic pandemic response treaty was drafted among member states of the World Health Organization (WHO). This was accomplished without US participation as Trump withdrew the US from the WHO. The treaty ensures better sharing of information, supplies, pharmaceuticals, and technology to ensure a fair and equitable distribution worldwide.

Take Action

Inaction is not an option while public health is under attack with the dismantling of health and medical research workforce, defunding of HHS grants and programs (including over 17,000  HIV and AIDS and 400 COVID related CDC grants), potential disastrous cuts to Medicaid, threats to universities’ federal funding affecting clinical care and research, threats to civil and constitutional rights, erasing basic human rights and dignity and loss of more safety nets.

For healthcare workers, hospital workers, and researchers:

  • Sign the “Code Blue for Democracy” open letter from a growing national coalition of healthcare providers and researchers to urge hospitals and universities to defend science and democracy! Science, healthcare, and academic freedom are under attack by the Trump administration and its proxies.
  • This op ed, co-authored by one of People’s CDC volunteers, has clear steps that hospitals and workers can take to create sanctuary hospitals. 
  • These slides from the California Collaborative for Immigrant Justice outline what to do if ICE shows up at a medical facility. Help prepare everyone in your clinic or hospital to protect the constitutional rights of your patients.

For public health workers and physicians, stay connected with these advocacy tools: 

For faculty:

For everyone:

Continue your local and federal legislative advocacy – that and lawsuits are effective for making our voices heard.

And, as always: 

On Thursday, April 24th from 11:30 am to 12:30 pm ET, join us for an important panel discussion about protecting patients from infectious disease and deportation through mask and vaccine advocacy, and collective action to get ICE out of our hospitals. Save this date and time on your calendar and register via zoom.

Other Viruses and Health Risks

Measles 

The measles outbreak continues. From the CDC’s summary, there were 800 confirmed cases in 2025 as of April 18, 2025, This is nearly 200 more cases (over 30% increase) since our last Weather Report two weeks ago. The Measles Mumps and Rubella (MMR) vaccination status from these patients were: Unvaccinated or Unknown: 96%;  One MMR dose: 1%; Two MMR doses: 2%.  

To protect communities from measles, at least 95% of the population needs to have received the MMR vaccine. For the school year 2023 – 2024, fewer than 95% of kindergartners received an MMR vaccine. 

The MMR vaccine is safe and effective, and is our most effective prevention tool. A recent Health Alert Network advisory recommends that travelers, regardless of their destination, stay up to date with the MMR vaccine. This advisory also includes additional vaccination guidance for people in outbreak areas and what to do if you suspect you have measles.

Bird Flu 

Bird flu (H5N1) continues to spread among wild birds, chickens, and cows, with 31 new cases in dairy cows detected this month. There are now at least 70 known cases of humans infected with H5N1 in the U.S. There is still no known person-to-person transmission. Wastewater monitoring is crucial for understanding where bird flu is spreading. Although the FDA has increased some funding for this, it was at the expense of other fresh food access safety nets

Frequently Asked Questions (FAQs)

The People’s CDC is a coalition of public health practitioners, scientists, healthcare workers, educators, advocates and people from all walks of life working to reduce the harmful impacts of COVID-19.

We provide guidance and policy recommendations to governments and the public on COVID-19, disseminating evidence-based updates that are grounded in equity, public health principles, and the latest scientific literature.

Working alongside community organizations, we are building collective power and centering equity as we work together to end the pandemic. The People’s CDC is volunteer-run and independent of partisan political and corporate interests and includes anonymous local health department and other government employees. The People’s CDC is completely volunteer run with infrastructure support being provided by the People’s Science Network.

Though the People’s CDC was supported initially through a Robert Wood Johnson Foundation grant, that grant has long expired. We no longer pursue or accept grant funding. We are now entirely funded by people who donate to us. Most of these donations make their way to us through our Substack platform (which anyone can access for free!) or through purchases of People’s CDC swag. Our website now has a donate link for anonymous donations.

The content that we put out is entirely created by volunteers who receive no funding for their work. We pay one person for their labor–a digital organizer. They help us update and maintain our website, make sure we all know what meetings are happening and when, post our content on social media, and monitor our email. They also act as the point person between our organization and our fiscal sponsor, People’s Science Network.

We also pay for a People’s CDC T-shirt for any volunteer who wants one.
