A common killer bug is endangering Americans: ‘Pandemic in plain sight'
Five years after the worldwide hyperfocus on COVID-19 began, some are concerned about the next pandemic — whether it could be caused by influenza, bird flu or another pathogen.
Too easily overlooked are non-influenza, non-COVID viruses and bacteria that are burgeoning and spreading unchecked — both in the U.S. and around the world. While they may not cause the next pandemic, they do cause a lot of illness and death.
One such bacteria is Streptococcus Group A, an old enemy that colonizes the throat and tonsils of close to 20% of U.S. children, according to Dr. Joshua Osowicki, team leader and senior research fellow at the Murdoch Children's Research Institute in Melbourne, Australia.

This problematic bacterial strain is easily treated with penicillin drugs when it causes a clinical infection, Osowicki told Fox News Digital in an on-camera interview. (See the video at the top of this article.)
But the problem, he said, is that because the bacteria may be harbored, the diagnosis isn't always found early enough.

Scarlet fever and rheumatic fever/rheumatic heart disease can result from recurrent or untreated strep — and they are on the increase again in areas without adequate medical care, including parts of the U.S.
"Rheumatic heart disease is a chronic, non-infectious illness that occurs after untreated group-based streptococcal infections — and almost certainly after multiple untreated, group-based streptoococcus infections," Osowicki said.
Strep Throat Infections Have Spiked Above Pre-covid Highs, Says Report: 'We've Missed Cases'
His research reveals that the prevalence of a life-threatening invasive version of strep Group A — which can include deep-rooted skin infections, sepsis, meningitis and deadly pneumonia — is on the rise around the world.
The aggressive skin infections, which are associated with intravenous drug use, can lead to the need for repeated surgeries, along with antibiotics.
In the U.S., there have been more than double the annual incidents of invasive Group A strep in 10 states, affecting about 35 million Americans between 2013 and 2022, with 21,000 cases and about 2,000 deaths, according to Osowicki.
"In many ways, it's a pandemic in plain sight," he said of Group A strep, adding that close to a billion people likely experience symptomatic disease from the bacteria each year.
The important thing with group A strep, according to the doctor, is that antibiotic resistance isn't the primary issue.
"Group A strep is reliably killed by penicillin — and has been since 1941 when penicillin was introduced," Osowicki noted.
"The point is that it actually does its damage in severe, life-threatening cases before the patient receives antibiotics. There's this period where it is too hard to diagnose and treatment comes too late."
In those cases, he said, the patients need ICUs, surgery and "the most intensive treatment we have to offer."
Among patients over the age of 65 or so, a quarter of them will die with this form of the disease, according to Osowicki.
There is not currently a vaccine for Group A strep.
While the more common form of strep throat and minor skin infections are "less scary," Osowicki warned of the dangers of overlooking the more invasive version of the disease.

"We look away sometimes from the life-threatening infections that we struggle to prevent, diagnose and treat, (until) these become the front-page sepsis cases that you see in the newspaper many weeks of the year," he said.
"They're headline-catching cases. They're the cases like Rory Staunton in New York, whose tragic death (in 2012 from sepsis) really triggered the state census mandates across the U.S."
The need for an effective vaccine is clear — both for invasive strep and the more common variety. Osowicki and others in his group are working hard on developing them.
"The current thrust of my research is all vaccine-related," he shared. "We do what are called human challenge trials, where we deliberately infect healthy adult volunteers with group A strep, painting it on their tonsils. And we do that in a very careful way, in an inpatient environment."
The researchers also provide early antibiotic treatments and collect throat swabs, blood and saliva to study how the human-only pathogen works and to explore ways to stop it.
"The ultimate goal is that it becomes a really high-powered platform to establish the efficacy of vaccines," said Osowicki.
There are many vaccine candidates in various stages of development, from the protein-adjuvant kind (like Shingrix or the Novavax COVID vaccine) to the MRNA platform and various other kinds, the researcher said.
"We're working with every vaccine company that has a group-based streptococcal vaccine candidate in development," he said.

There are up to 10 different group-based strep vaccines in development, ranging from entirely pre-clinical vaccines that have never seen a person to vaccines that have been tested in phase 1 trials, Osowicki noted.
He said he is concerned about vaccine skepticism, particularly after the COVID pandemic, which can keep people from trusting the emerging science.
Still, the researcher is excited about the future of the strep A vaccine and others, though he expects it could take at least five to 10 years before a worthy candidate reaches doctors' offices.

The new vaccine will be geared toward adults with skin infections, as well as the many millions of children who are at risk of both mild and severe disease.
The goal, Osowicki said, is to "create a vaccine that the world wants, that the world accepts, that the world says is safe, and that will help our children."

Mobile clinics aim to boost rural health care measles vaccinations amid outbreak
The "Wellness on Wheels" program launched in spring of 2024. (Courtesy of South Dakota Department of Health) The South Dakota Department of Health plans to send its fledgling mobile clinics to underserved and undervaccinated areas of the state in response to the nationwide measles outbreak making its way to the state. Last year, South Dakota reported its first measles case in nine years. The state Department of Health recently reported the state's first case this year in Meade County in western South Dakota. Last week, on Friday, a second case was reported in Rapid City. People who visited Sam's Club in that city on June 1, or Dakota Premier Medical Center the following day were urged by the department to monitor themselves for symptoms for 21 days. Measles is a highly contagious viral disease that spreads through the air. Those who lack immunity from vaccination or past infection are highly likely to catch it from an infected person. As surrounding states report more cases, Health Department Secretary Melissa Magstadt said the state's 'Wellness on Wheels' clinics can help encourage vaccinations. 'I question it myself': South Dakota vaccination rates fall amid mistrust and misinformation The fleet boasts five vehicles equipped to provide immunizations, test for sexually transmitted diseases such as syphilis, as well as provide screenings, prenatal care and other support. The effort fills in gaps to public health care access across the state, especially in rural and tribal communities, Magstadt said. 'It's about how we can actively use these tools to reach underserved populations,' Magstadt said. 'It's not something I would have thought about looking to leverage for something like measles vaccinations before.' The department hasn't decided where to send their fleet. Counties with the fewest kindergarteners vaccinated per capita for measles, mumps and rubella include Faulk, Jones and Hutchinson, state data shows. South Dakota counties that share tribal land and rural counties in south-central areas of the state rank the worst for clinical care use and access in the state, according to the University of Wisconsin Population Health Institute's 2023 report. Federal COVID relief funds paid for Wellness on Wheels. 'Because of the pandemic, public health infrastructure was found to be wanting,' Magstadt said. That infrastructure missed 'critical pieces' that hadn't been invested in, she said, such as health care access in rural areas. More than a hundred rural hospitals in the U.S. have closed in the last decade. The program, launched in April of last year, cost about $800,000 in federal funding. The state's public health COVID funding was also used to support a community health worker program, update emergency medical service equipment and telemedicine access, analyze the state of emergency medical services in South Dakota, and build a Public Health Lab and department training center. Magstadt said staff working with the Women, Infants and Children (WIC) program requested the mobile units. WIC is a federal-state program that provides healthy food, nutrition education and health care referrals to low-income women and their young children. So far, Wellness on Wheels staff have mainly driven to events. Magstadt said the department has focused on increasing awareness of the program and building trust in communities and among tribal leaders. She plans to have staff drive the buses to rural communities more regularly to increase exposure and encourage use. 'Being consistently at a facility or place every other week will help people find it,' Magstadt said. 'We talk about the importance of STI testing, for example, but if you don't know where to get tested then that's another barrier.' Magstadt plans to have the department park one of the vehicles at a homeless shelter in Rapid City this summer as well to encourage underserved urban communities to seek services. 'We like people to be connected to primary care services, but there are unique situations where it's harder to get to health care facilities,' Magstadt said. She compared the mobile clinics as a return to home visits by doctors. That practice largely ceased in the 1960s due to cost efficiencies. 'It's a part of this menu of health care access and options no longer requiring people to come to a clinic or health care system,' Magstadt said, 'but health care being taken to patients and families who need it.' Mobile health care clinics are available in every state. They range from public entities like South Dakota's Wellness on Wheels, to specialized, private care. Other mobile clinics operating in South Dakota, according to Mobile Health Map, include: Delta Dental Mobile Program Horizon Health on Wheels Midwest Street Medicine Mobile Women's Health Unit VA Mobile Counseling Program

Give Your Kidneys Some Love With These 13 Superfoods
Your kidneys are vital to your overall health. According to the US Centers for Disease Control and Prevention, more than one in seven adults in the United States has chronic kidney disease. Your kidneys work around the clock to filter out waste and excess fluid, helping to prevent serious health problems like heart disease, infections, anemia, depression and even loss of appetite. Your diet and gut health also play a major role in your wellness, especially when it comes to keeping your kidneys healthy. There are 13 superfoods you should keep in mind when considering natural ways to give your kidney health a boost. Read more: 6 Important Blood Tests You May Need for Your Overall Health Best Meal Delivery Services See at Cnet This nutrient-dense vegetable is low in both potassium and sodium while packing in fiber, vitamins C and K and more. Plus, cabbage is versatile. You can use it in salads and slaws, but you can also use it as a wrap for tacos, sandwiches and more. Fish delivers protein, and when you choose a fatty fish like tuna, salmon or trout, you're also getting omega-3 fatty acids. Omega-3 fats may help reduce fat levels (triglycerides) in the blood and may also lower blood pressure, according to the National Kidney Foundation. If you have CKD, you may need to keep an eye on the phosphorus and potassium levels of the fish you choose. The National Kidney Foundation has a chart you can use to determine levels in specific types of fish. Although, it's best to consult with your doctor. Like cabbage, bell peppers pack in lots of good nutrients with low levels of potassium. With them, you get vitamins B6, B9, C and K, plus fiber. They deliver antioxidants too. You can slice them and eat them with dips or roast them and add them to dinner. Cranberries help to prevent urinary tract infections. These usually stay in your bladder, they can travel up to your kidney, making kidney problems worse. Fortunately, regularly consuming cranberries can help you avoid this unwelcome situation. Plus, cranberries have antioxidants that can help fight inflammation, and they can boost your heart and digestive health. It turns out, these tart berries aren't just for the Thanksgiving table. We've talked about some of the best foods for kidneys, but you can take it a step further. The question is: What foods help repair kidneys? Blueberries deliver. With high levels of antioxidants and loads of vitamin C and fiber, blueberries are all-around healthy. They can also help to reduce inflammation and support bone health, reversing some of the issues that can come with CKD. There are plenty of reasons to turn to dark, leafy greens like spinach or kale. They deliver so many nutrients that they can help you get key vitamins and minerals, plus immunity-boosting benefits. Be advised that greens can come with a decent amount of potassium. If you have CKD, talk to your doctor before adding more of these to your diet. Rich in antioxidants and healthy fatty acids, olive oil can boost your overall wellness. A study from Harvard University found that olive oil may lower cholesterol levels and the risk of cardiovascular disease, dementia and some types of cancer. Beyond all this, it can help you add flavor to dishes without turning to salt or butter. To get more antioxidants, choose unrefined or cold-pressed olive oil that's virgin or extra virgin. Another antioxidant-rich, inflammation-fighting food, garlic also contains a specific compound called allicin. For people with CKD, allicin — an active compound found in garlic — worked just as effectively to help protect kidney health as a prescription drug. If you're looking for the best foods for your kidneys, garlic has to make the list. Plus, it's an excellent way to add flavor when you're skimping on salt. From the same family as garlic, onions give you another excellent and salt-free way to add flavor (bonus points if you saute them in olive oil). Onions also deliver important nutrients like vitamins B6 and C, manganese and copper. They also contain quercetin, a chemical that can help your body fight cancer, and organic sulfur compounds that can reduce your risk of high blood pressure, stroke and heart disease. Cauliflower brings the crunch, paired with plenty of vitamins C, B6, B9 and K, along with fiber. It also contains compounds your body can use to neutralize certain toxins, a big help when your kidneys aren't doing their best filtration work. Cauliflower does contain some potassium and phosphorus, though, so while it makes the list of foods good for kidneys, people with CKD may want to moderate their intake. Egg whites are specifically recommended for people with kidney problems. They give you a way to increase your protein levels -- which can be important with later-stage CKD, especially if you're on dialysis. Arugula is packed with nutrients your body needs like magnesium, iron, calcium and vitamins A, B9, C and K. Plus, it's antioxidant-rich and has glucosinolates, which can help your body protect itself against a range of cancer types. You can eat arugula raw (it's a great salad base), but you can also sprinkle it over whatever you're whipping up. It's great on pizzas, in omelets and with pasta, for example. Apples deliver the cancer-fighting quercetin and fiber that can help to keep your cholesterol and blood sugar at healthy levels. They've got plenty of antioxidants. Better yet, they're easy to work into your diet. Leave a bowl of apples on your counter and you'll have a kidney-healthy, grab-and-go snack whenever you need one.

Nearly 11 million Americans would lose insurance under Trump's tax bill, analysis says
About 10.9 million Americans would lose health insurance coverage under the President Donald Trump's tax cut bill that cleared the House but faces a tough test in the Senate, a new analysis shows. The nonpartisan Congressional Budget Office said about 10.9 million Americans would lose health insurance coverage through 2034 under the bill, including 1.4 million undocumented residents who get coverage through state-funded programs. The legislation that cleared the House would require nondisabled Americans on Medicaid to work at least 80 hours per month or qualify for an exemption, such as being a student or caregiver. The bill also would strip coverage to immigrants who get Medicaid through state-funded programs. The analysis said the bill would cut federal spending by about $1.3 trillion through 2034. But it would also deliver tax cuts of $3.75 trillion, and the federal deficit would increase nearly $2.4 trillion over the next decade. Health analysts said if the Medicaid changes as well as tweaks to the Affordable Care Act marketplace clear Congress, the effects on health insurance coverage would be significant. The CBO earlier estimated nearly 4 million people would lose health insurance coverage through 2034 if Congress did not extend sweetened COVID-19 pandemic-era tax credits that have made ACA plans more affordable for consumers. Trump's Medicaid overhaul as well as the expiration of the more generous ACA tax credit could jeopardize health insurance coverage for nearly 15 million people, said Kathy Hempstead, a senior policy officer at the Robert Wood Johnson Foundation. "We're making a giant U-turn here," said Hempstead. "Are we really going to be a thriving, productive society if we have a huge share of our population uninsured?" Hempstead said the uninsured might delay care and accrue more medical debt. She also said hospitals and doctors also will take a financial hit as uncompensated care rises. "There's going to be a big hit on on the health care economy as people stop getting care and start trying to get care that they can't pay for," Hempstead said.
