Latest Biobot data shows U.S. COVID wastewater levels are rising again, and higher than they have ever been compared to the same date in previous years.

In other words, COVID levels are still high and taking longer to go down after this winter's peak. Keep taking precautions. Chart of U.S. COVID wastewater levels from Biobot data
This chart compares U.S. COVID wastewater levels from each year. It shows that COVID wastewater levels are higher in February 2024 than they have ever been compared to February in previous years of the pandemic, when COVID levels fell more quickly after the winter peak. Chart comparing U.S. COVID wastewater levels from each year, using data from Biobot.
It's important to note that there's a discrepancy between the Biobot and CDC data. The CDC data shows that U.S. COVID wastewater levels are plateauing rather than rising again. Chart showing U.S. COVID wastewater levels using CDC data
Here's a rough comparison of the Biobot and CDC COVID wastewater data in one chart, using % change.

Both show that COVID wastewater levels have stopped falling quickly, and are still high. But Biobot shows an uptick in COVID levels, while CDC data shows a plateauing of levels. Chart comparing Biobot and CDC data by % change in wastewater levels
Also noteworthy is that if you zoom in and look at the CDC's regional COVID wastewater data, you can see that all regions show an uptick in COVID levels at some point in the last month. Chart showing COVID waste water levels by U.S. region, using CDC data.
Though there are slight differences in Biobot and CDC data (which hopefully will be ironed out), the takeaway is the same: US COVID levels are still HIGH, and it's taking LONGER to return to lower levels than during previous winters of the pandemic. Keep taking precautions.

The CDC wants to stop telling people to isolate for five days when they are sick with COVID. This is a reckless, anti-public health policy that contravenes science, increases disease spread, and puts everyone at greater risk. 🧵 The Washington Post: CDC plans to drop five-day covid isolation guidelines  Americans who test positive for the coronavirus no longer need to routinely stay home from work and school for five days under new guidance planned by the Centers for Disease Control and Prevention.
The truth is COVID is still killing and disabling way too many people, and too many are locked out of society and can’t even access medical care safely due to high levels of COVID transmission. We still need strong isolation guidelines and better public health protections. /2
People look to the CDC for science-based guidance. But this policy change goes against the science and will cause more misinformation, misleading people to think that they can’t spread COVID if they “only” have “mild” symptoms. /3

Historically, extremist groups exploit crises to advance their bigoted political agenda. It's terrifying that the same thing is happening here with COVID in 2024, and few political groups on the left recognize this.

According to a new study, up to 75% of adults have concealed an infectious disease from others in order not to miss work, travel, or social events. Unacceptable behavior. cidrap.umn.edu/misc-emerging-…
This is also why we need better structural supports like increased paid sick days. There are many people who want to do the right thing and stay home when they are sick, but can’t afford to miss work.
Wow. 61% of healthcare workers said they concealed illness due to not wanting to miss social engagements, school, or work.

Meanwhile, so many healthcare workers aren't wearing masks despite high levels of respiratory viruses.

This is an abdication of responsibility to patients. Eighty-five percent of students reported concealing a contagious illness, as well as 61% of healthcare workers. Only 8% of healthcare workers and 3% of students said they concealed illness due do a university policy requirement. Instead, almost all efforts at hiding were made because of not wanting to miss social engagements, school, or work.

Latest data from the CDC: Only 21.5% of US adults have gotten their updated COVID vaccine. Chart: Cumulative Percentage of Adults 18 Years and Older Vaccinated with the Updated 2023-24 COVID-19 Vaccine  Data Source: National Immunization Survey-Adult COVID Module
Only 6.8% of people who are uninsured have gotten their updated COVID vaccine, compared with 23.5% of people who have insurance.

Despite there being a bridge program for people who are uninsured, this illustrates the problems of access and the update COVID vaccine rollout.

This month, advocates have gotten officials to:

➡️Do PSAs on masks and clean air
➡️Distribute free N95s
➡️Issue masking guidelines
➡️Reintroduce mask requirements in hospitals
➡️Hold a Senate hearing on Long COVID
➡️Halt CDC's plan to weaken infection control

Advocacy works!

CDC advisers planned to put out weakened hospital infection control guidelines, which suggested that N95 respirators are no more protective than surgical masks.

Advocates pushed back, and now the CDC are reconsidering and sending the draft back for revision!
Based on the significant interest in the draft recommendations, CDC is taking a proactive step of communicating back to HICPAC some initial questions and comments on which we would like additional consideration before submitting the guideline into the Federal Register for public comment. In addition, CDC is working to expand the scope of technical backgrounds of participants on the HICPAC Isolation Guideline Workgroup and eventually among the committee members through established processes in accordance with the Federal Advisory Committee Act (FACA) regulations and guidance. The expanded wo...
Another issue relevant to preventing transmission through air is to make sure that a draft set of recommendations cannot be misread to suggest equivalency between facemasks and NIOSH Approved respirators, which is not scientifically correct nor the intent of the draft language. Although masks can provide some level of filtration, the level of filtration is not comparable to NIOSH Approved respirators. Respiratory protection remains an important part of personal protective equipment to keep healthcare personnel safe.
