A New Report Outlines a Vision for National Wastewater Surveillance

Wastewater surveillance supplied useful public well being info through the Covid-19 pandemic and deserves “additional growth and continued funding,” based on a brand new report launched by the Nationwide Academies of Sciences, Engineering and Drugs on Thursday.

Though the pandemic spurred the fast growth of wastewater surveillance, the present system sprung up in an advert hoc approach, fueled by volunteerism and emergency pandemic-related funding, based on the report. It is usually concentrated in main metropolitan areas, leaving many communities behind.

“The present system is just not absolutely equitable,” Dr. Man Palmer, a professor of pathology and infectious ailments at Washington State College and chair of the committee that wrote the report, stated at a webinar on Thursday.

The problem now, he stated, was to maneuver from this type of grass roots system to a extra standardized, “consultant” nationwide system.

The report was created by a committee of specialists appointed by the Nationwide Academies on the request of the Facilities for Illness Management and Prevention. It was sponsored by the U.S. Division of Well being and Human Companies.

The report outlined what such a system may appear like, noting that it ought to have the ability to observe quite a lot of potential threats, which might embody future coronavirus variants, flu viruses, antibiotic resistant micro organism and fully new pathogens.

Some wastewater surveillance websites have already begun monitoring further pathogens, together with the mpox virus and poliovirus, however a nationwide system would require sustained federal funding and would must be carried out equitably throughout areas and demographic teams, the report notes.

Ideally, the system would mix information collected from communities throughout the nation with monitoring of sewage at sure “sentinel websites,” comparable to giant worldwide airports and zoos, the place new pathogens or variants is likely to be noticed early.

People who find themselves contaminated with the coronavirus shed the virus of their stool. Monitoring ranges of the virus in sewage supplies well being officers with a approach to maintain tabs on how prevalent the virus is in a neighborhood, even when folks by no means search testing or well being care. It has turn out to be an particularly useful device as coronavirus testing has shifted to the house, making official case counts much less dependable.

Wastewater surveillance is just not a novel thought; it has been used for many years to trace polio, for example. But it surely was not a extensively used public well being device in america till the Covid-19 pandemic hit. Over the previous couple of years, many localities and establishments created their very own wastewater surveillance methods.

Within the fall of 2020, the C.D.C., in partnership with the D.H.H.S., established the Nationwide Wastewater Surveillance System to coordinate and centralize a few of these efforts.

As of October, the N.W.S.S. included greater than 1,250 sampling websites throughout the nation, overlaying greater than one-third of the U.S. inhabitants. However these websites had been primarily close to main cities — they usually had been particularly sparse in elements of the South and West.

Nonetheless, these methods paid actual dividends through the pandemic, based on the report. Wastewater information helped native well being officers decide whether or not an infection charges had been rising or falling in a selected neighborhood. In some situations, particularly when testing was restricted, wastewater proved to be a helpful early indicator of a surge, with ranges of the virus in wastewater starting to rise days earlier than the official case numbers did.

Wastewater surveillance additionally helped specialists observe the arrival and unfold of recent coronavirus variants. Within the Bay Space, for example, scientists discovered the Omicron variant in native wastewater earlier than clinicians detected Omicron infections in sufferers.

The information knowledgeable coverage selections as properly. Universities used wastewater outcomes to strategically check sure pupil populations, whereas state well being officers used them to find out the place to ship extra sources. Clinicians used information in regards to the unfold of recent variants to determine when to make use of or to cease utilizing sure monoclonal antibodies, a few of which had been solely efficient in opposition to sure variations of the virus.

The report lays out suggestions for creating a extra complete nationwide system. For instance, it advises the C.D.C. to conduct outreach to public well being officers in areas which are presently underserved by wastewater surveillance and to assist cut back the monetary obstacles of becoming a member of the nationwide system, maybe by offering funding. The company must also educate the general public about how the knowledge is used and set up an ethics committee to develop tips about information sharing and entry, based on the report.

“It must be very clear on how that information is shared,” Dr. Palmer stated, “to obviously talk how the info are used and never used with the general public and to keep up a robust firewall that precludes use by legislation enforcement.”

Wastewater surveillance is just not a panacea and could also be most helpful when mixed with different kinds of public well being information, the committee stated. Furthermore, there are nonetheless quite a few scientific unknowns, together with whether or not some pathogens will be reliably detected in wastewater and the way altering inhabitants immunity, via vaccination or an infection, may have an effect on the patterns within the wastewater.

And never all public officers are keen on making use of the info, typically for political causes, the committee famous. “There are some fairly entrenched positions at this level about pandemic response that could be troublesome to beat,” Michelle Mello, a professor of legislation and of well being coverage at Stanford College, stated on the webinar on Thursday.

She added, “There’s extra political will in some locations than others.”

Opinion: Most older Americans who need hearing aids don't use them. Here's how to change that

Opinion: Most older Americans who need hearing aids don't use them. Here's how to change that

Having depended on hearing aids for nearly three decades, I’m astounded by the lack of Medicare coverage for devices that can solve a problem afflicting tens of millions of older Americans.

Nearly two-thirds of Americans over age 70 have some degree of hearing loss, and over half of those 75 and older experience impairment serious enough to be considered disabling. But most don’t wear hearing aids.

Because the legislation that created Medicare nearly 60 years ago specifically excluded hearing aids, those who rely on the program’s traditional coverage must pay for them out of pocket. That expense is among the chief barriers to wider use of the devices.

Age-related hearing loss impedes basic communication and the relationships that depend on it. Expanded access to hearing aids could therefore do no less than enable more older Americans to establish and maintain the social connections that are essential to a meaningful life.

Hearing loss is like an invisible, muffling curtain that falls in front of anyone speaking. Asking people to repeat themselves can yield irritated and hurtful responses. And it’s hopeless to ask a soft-spoken person to speak up. Sometimes it’s easier just to nod and smile.

Many older people I know choose to avoid social gatherings altogether because they can’t hear well. Without hearing aids, I’d stay home too.

Hearing loss can harm one’s health in other ways. For example, I’ve written about the need for a comprehensive approach to reducing cancer risk at older ages, including preventive services such as colorectal cancer screening. But these services rely on conversations between patients and their healthcare providers. An older patient’s ability to hear and understand such conversations shouldn’t be taken for granted or ignored.

The Food and Drug Administration did improve access to hearing aids by making some of them available without a prescription in 2022, but the over-the-counter devices are inadequate for serious hearing loss like mine. My private health insurance, meanwhile, started covering hearing aids a few years ago, providing up to $2,500 for them every five years. One hearing aid alone can cost that much or more, however.

Despite its limitations, my private coverage for hearing aids is better than nothing, which is what traditional Medicare provides.

Hearing loss is more common among lower-income people and those without advanced education. The toll from noisy workplaces compounds age-related hearing loss for some. One analysis found that most Americans with a serious hearing disability can’t afford the typical price of hearing aids.

Many of the older adults who can’t come up with these significant out-of-pocket expenses spent their working years in low-wage jobs that our country depends on. Denying them treatment for their hearing loss is a lousy way to treat people who gave years of service to our society.

Although some older adults with hearing loss won’t benefit from hearing aids, Medicare coverage for the devices might encourage more beneficiaries to get their hearing tested so they can get the treatment that’s right for them. And while Medicare coverage alone won’t address the stigma some people associate with hearing aids, the availability of newer, more comfortable and less obvious technology might win over some refuseniks.

Legislation reintroduced with bipartisan support last year would finally correct this glaring gap in Medicare coverage by removing the hearing aid exclusion from the law. There’s no reason to delay action on this any longer. Are our representatives listening?

Second human case of bird flu detected in Michigan dairy worker

A second human case of bird flu in a diary worker has been confirmed in Michigan, state and federal health officials announced Wednesday.

The symptoms were mild, consisting of conjunctivitis. The Texas dairy worker who contracted the virus in March also came down with pink eye.

At a press call on Wednesday, Nirav Shah, principal deputy director of the U.S. Centers for Disease Control and Prevention, said the finding was “not unexpected” and that it was a scenario “that we had been preparing for.”

He said that since the discovery of H5N1 in dairy cattle, state and federal health officials have been closely monitoring farmworkers and slaughterhouse workers and urging farmers and farmworker organizations to “be alert, not alarmed.”

Federal officials say they still believe the human health risk of bird flu is low; however, it underscores the need for people who are interacting with infected or potentially infected farm animals or birds to take precautions, including avoiding dead animals and wearing personal protective equipment (PPE) if there’s a need to be in close contact.

Though a nasal swab from the person in Michigan tested negative for influenza, an eye swab from the patient was shipped to the CDC and tested positive for influenza A(H5N1) virus.

This is the third case of H5N1 reported in the United States. A poultry worker in Colorado was identified in 2022.

Although the symptoms in the three farmworkers in the U.S. have been mild, people elsewhere in the world have suffered more severe illness, including death. According to the World Health Organization, between Jan. 1, 2003, and March 28, 2024, there have been 888 cases of human infection from 23 countries; 463 were fatal.

In preparation for a more widespread outbreak, the CDC updated its guidance for PPE in dairies and issued a nationwide order for healthcare providers to be on the lookout for novel influenza.

On Tuesday, the CDC asked clinical laboratories and health departments to increase the number of influenza samples being analyzed “to maximize the likelihood of catching a case of H5N1 in the community,” Shah said.

The US Department of Agriculture is also expanding its surveillance and support by providing $1500 to non-infected farms to beef up biosecurity, and $100 to producers who want to buy inline samplers to test their milk. The agency will also provide $2000 per farm to cover veterinary fees for testing, as well as shipping costs to send those tests to laboratories for analysis.

There have been no cases of H5N1 detected in California’s dairy herds.

Officials said ongoing analysis of the nation’s dairy supply suggests it is safe to consume, Despite the risk to human health being low, an official with the Administration for Strategic Preparedness and Response said it will make Tamiflu available upon request “to jurisdictions that do not have their own stockpile and are responding to pre-symptomatic persons with exposure to confirmed or suspected infected birds, cattle or other animal exposures.”

Dawn O’Connell, assistant secretary of the preparedness agency, said it started the “fill and finish” process for approximately 4.8 million doses of vaccine “that is well matched to the currently circulating strain of H5N1 through the national pre-pandemic influenza vaccine stockpile program.”

She said the decision to get started on H5N1 vaccines was not a response to any heightened concern, but since it takes several months to fill and finish vaccine doses, the agency “thought it made sense given what we were seeing.”

Gas stoves may contribute to early deaths and childhood asthma, new Stanford study finds

Gas stoves may contribute to early deaths and childhood asthma, new Stanford study finds

Lung-irritating pollution created by cooking with gas stoves may be contributing to tens of thousands of premature deaths and cases of childhood asthma in the United States, according to a new study published in the journal Science Advances.

For decades, scientists have known the flames from a gas stovetop produce nitrogen dioxide, a pungent gas that can inflame a person’s lungs when inhaled. But for the first time, a team of researchers from Stanford University and Oakland-based research institute PSE Healthy Energy published a nationwide estimate of the long-term health consequences associated with cooking with natural gas and propane stoves.

Researchers concluded that exposure to nitrogen dioxide emissions alone may contribute to nearly 19,000 premature deaths in the United States each year. It has also resulted in as many as 200,000 current cases of pediatric asthma compared with cooking with electric stoves, which do not produce nitrogen dioxide.

Aggressive and impactful reporting on climate change, the environment, health and science.

Stanford researcher Yannai Kashtan noted higher levels of pollution were correlated with the amount of gas that was burned. But pollution also accumulated at higher levels inside smaller homes.

“If you live in a smaller house, you’re exposed to more pollution, and that can lead to income and racial disparities in exposure,” Kashtan said. “In general, folks living in neighborhoods with higher levels of outdoor pollution also tend to have higher indoor pollution. So this environmental injustice extends indoors as well.”

The American Gas Assn., a trade organization representing more than 200 local energy companies nationwide, dismissed the findings as “misleading and unsupported.”

“Despite the impressive names on this study, the data presented here clearly does not support any linkages between gas stoves and childhood asthma or adult mortality,” the association’s president and CEO, Karen Harbert said in a statement earlier this month.

The study is the latest examining the serious health effects associated with breathing fumes from gas stoves, which release planet-warming carbon emissions and a variety of air pollutants. In recent years, the popular household appliance has become a political hot-button issue as policymakers and regulators have weighed environmental impacts against consumer choice.

Many large cities in California, including Los Angeles, have moved toward phasing out gas stoves in newly constructed residences. Earlier this month, the California Assembly advanced a bill to the Senate that would require gas stoves to come with warning labels detailing the pollution and health effects that can arise from cooking with gas.

Gas stoves emit a variety of pollutants, including asphyxiating carbon monoxide, cancer-causing formaldehyde and benzene. The flame also creates nitrogen dioxide, a precursor to smog and a pollutant that can cause difficulty breathing.

Environmental groups say consumers should be notified about these pollutants and the potential harm they can cause.

“Gas stoves create pollution in our homes, increasing the risk of childhood asthma and other respiratory problems for our families,” said Jenn Engstrom, state director for California Public Interest Research Group. “However, this risk has largely been hidden from the public. Consumers deserve the truth when it comes to the danger of cooking with gas. Warning labels will give consumers what they need to make informed decisions when they purchase appliances for their homes.”

Kashtan and other researchers had previously discovered cooking with gas stoves presented a similar cancer risk as inhaling second-hand cigarette smoke. They also found some gas stoves leaked contaminants even when the burners were off.

The effects are especially devastating to children, whose smaller and still-developing lungs need to take more breaths than adults, Kashtan said. Older adults, especially those with cardiovascular or respiratory illness, are also more vulnerable to pollution from gas stoves.

To alleviate indoor air pollution, experts recommend using ventilation hoods and opening windows while cooking,

Starting in 2008, California required new and redeveloped homes to have ventilation that could prevent pollution from building up indoors. But during their research, measuring emissions in more than 100 households across the country, Yannai said they found many kitchens didn’t have ventilation hoods at all.

Although the health effects of breathing these pollutants are clear, researchers still wonder to what degree these conditions could be reversible. As communities take steps to mitigate their exposure or transition away, he said we could soon see the results.

“It’s never too late to stop breathing in pollution,” he said.
