Third human case of West Nile virus in Illinois reported in DuPage County
The DuPage County Health Department confirmed the case on Thursday.
The department said the individual is a Glen Ellyn resident in their 50s, and the onset of symptoms was mid-July.
The Centers for Disease Control and Prevention first confirmed in June that a person downstate, specifically in Southern Illinois, was hospitalized due to complications of the virus.
The second was confirmed in Lake County on July 16. The resident was said to be in their 70s and became ill earlier in the month.
Symptoms of West Nile virus
While most people infected with the virus do not feel sick, about one in five will develop a fever and flu-like symptoms. Other symptoms include body aches, vomiting, diarrhea, or rash.
Severe illness can occur in about one in 150 people and is most likely to occur in people over age 55 or with weakened immune systems.
How to prevent it
West Nile virus is spread to people from infected mosquitoes, most commonly in the summer. Eight out of 10 people infected do not develop symptoms, according to the CDC.
Residents are also reminded to practice the three "R's"– reduce the number of mosquitoes and remove containers outside that hold water, repel mosquitoes by using insect repellent, and report areas where water sits for more than a week.
There are no medications to treat the virus. The only way to combat the virus is to prevent mosquito bites.

The Silent Symptom That Could Be a Sign of Blood Clots
The Silent Symptom That Could Be a Sign of Blood Clots originally appeared on Parade. Your blood's ability to clot after a cut or injury is an important defense mechanism to keep you from bleeding too much. But blood clots can cause serious health issues like strokes and heart attacks when they happen outside of that. About 900,000 people in the U.S. develop a blood clot each year, according to the Centers for Disease Control and Prevention (CDC). An estimated 60,000 to 100,000 Americans die from blood clot complications annually, making this an important health issue to be aware of. 'Awareness of blood clot symptoms is critically important because early recognition can be life-saving,' says, a pulmonologist at The Ohio State University Wexner Medical Center. 'Recognizing symptoms early allows for prompt medical treatment.' That can help lower the risk of permanent damage to organs or tissues, he points the problem: Not all symptoms of blood clots are obvious, and one in particular can be easily mistaken for other, much less severe health issues. Here's what doctors want you to keep in mind about this symptom, why it can be confused with other things and when to take action. 🩺SIGN UP for tips to stay healthy & fit with the top moves, clean eats, health trends & more delivered right to your inbox twice a week💊 How Do Serious Blood Clots Happen? Before we go over the symptom, it's important to first go over how blood clots can become serious. Blood clots that happen spontaneously usually start in the legs, explains , a vascular surgeon at MemorialCare Orange Coast Medical Center in Fountain Valley, California. 'They aren't life-threatening in themselves, but they occasionally dislodge and go to the lungs,' he says. This is called a pulmonary embolism. Related: With a pulmonary embolism, a blood clot gets stuck in an artery in the lung and blocks blood flow to part of the lung, Dr. Yi explains. There, it can cause permanent damage to the lungs, low oxygen levels in your blood, and damage to other organs in your body (from not getting enough oxygen), he says, adding, 'This can be life-threatening." The Silent Sign of Blood Clots To Know About, According to a Vascular Surgeon Back to that silent symptom: Shortness of breath is common with pulmonary embolisms. 'Shortness of breath is a hallmark symptom of pulmonary embolism because of how the condition affects the lungs and oxygen delivery,' Dr. Parson says. 'The blocked artery prevents blood from reaching parts of the lung, so oxygen can't be absorbed into the bloodstream efficiently, resulting in shortness of breath.' This blockage usually comes on suddenly, so the body doesn't have time to compensate for the lower-than-usual oxygen, he explains. That can lead to sudden and intense shortness of breath. Related: When Shortness of Breath Is a Sign of a Blood Clot Shortness of breath can also be a sign of a slew of other things, including being out of shape, having asthma or just having a cold, making this a tricky thing to pin on a blood clot. But doctors say there are a few key differences between 'regular' shortness of breath and feeling breathless due to a blood clot.'Standard shortness of breath usually comes with exercise or activity,' Dr. Yi says. 'With a blood clot, there is a sudden onset of shortness of breath where you feel like you can't catch your breath.' You may also start breathing faster than usual, he explains. Along with coming on hard and fast, shortness of breath from a blood clot tends to get worse with exertion or taking deep breaths, according to Dr. Other Signs of a Blood Clot and What To Do While sudden shortness of breath alone should raise concerns about a possible pulmonary embolism, there are other blood clot symptoms doctors warn should be on your radar: Fast breathing Chest pain (it usually gets worse when you cough or take a deep breath) A faster-than-usual heart rate Coughing, including coughing up blood Very low blood pressure Feeling lightheaded Fainting It can be tempting to write these signs off if you have one or two that can be explained away as something more minor. But doctors stress the importance of taking these seriously if you or someone around you has them. 'If someone experiences these symptoms, immediate medical attention is critical,' Dr. Parsons says.

Millions of people are suffering from brain fog. A new study will find out why
Millions of people who recover from infections like COVID-19, influenza and glandular fever are affected by long-lasting symptoms. These include chronic fatigue, brain fog, exercise intolerance, dizziness, muscle or joint pain and gut problems. And many of these symptoms worsen after exercise, a phenomenon known as post-exertional malaise. Medically the symptoms are known as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). The World Health Organization classifies this as a post viral fatigue syndrome, and it is recognised by both the WHO and the United States Centers for Disease Control and Prevention as a brain disorder. Experiencing illness long after contracting an infection is not new, as patients have reported these symptoms for decades. But COVID-19 has amplified the problem worldwide. Nearly half of people with ongoing post-COVID symptoms – a condition known as long-COVID – now meet the criteria for ME/CFS. Since the start of the pandemic in 2020, it is estimated that more than 400 million people have developed long-COVID. To date, no widely accepted and testable mechanism has fully explained the biological processes underlying long-COVID and ME/CFS. Our work offers a new perspective that may help close this gap. Our research group studies blood and the cardiovascular system in inflammatory diseases, as well as post-viral conditions. We focus on coagulation, inflammation and endothelial cells. Endothelial cells make up the inner layer of blood vessels and serve many important functions, like regulating blood clotting, blood vessel dilation and constriction, and inflammation. Our latest review aims to explain how ME/CFS and long-COVID start and progress, and how symptoms show up in the body and its systems. By pinpointing and explaining the underlying disease mechanisms, we can pave the way for better clinical tools to diagnose and treat people living with ME/CFS and long-COVID. What is endothelial senescence? In our review, our international team proposes that certain viruses drive endothelial cells into a half-alive, 'zombie-like' state called cellular senescence. Senescent endothelial cells stop dividing, but continue to release molecules that awaken and confuse the immune system. This prompts the blood to form clots and, at the same time, prevent clot breakdown, which could lead to the constriction of blood vessels and limited blood flow. By placing 'zombie' blood-vessel cells at the centre of these post-viral diseases, our hypothesis weaves together microclots, oxygen debt (the extra oxygen your body needs after strenuous exercise to restore balance), brain-fog, dizziness, gut leakiness (a digestive condition where the intestinal lining allows toxins into the bloodstream) and immune dysfunction into a single, testable narrative. From acute viral infection to 'zombie' vessels Viruses like SARS-CoV-2, Epstein–Barr virus, HHV-6, influenza A, and enteroviruses (a group of viruses that cause a number of infectious illnesses which are usually mild) can all infect endothelial cells. They enable a direct attack on the cells that line the inside of blood vessels. Some of these viruses have been shown to trigger endothelial senescence. Multiple studies show that SARS-CoV-2 (the virus which causes COVID-19 disease) has the ability to induce senescence in a variety of cell types, including endothelial cells. Viral proteins from SARS-CoV-2, for example, sabotage DNA-repair pathways and push the host cell towards a senescent state, while senescent cells in turn become even more susceptible to viral entry. This reciprocity helps explain why different pathogens can result in the same chronic illness. Influenza A, too, has shown the ability to drive endothelial cells into a senescent, zombie-like state. What we think is happening We propose that when blood-vessel cells turn into 'zombies', they pump out substances that make blood thicker and prone to forming tiny clots. These clots slow down circulation, so less oxygen reaches muscles and organs. This is one reason people feel drained. During exercise, the problem worsens. Instead of the vessels relaxing to allow adequate bloodflow, they tighten further. This means that muscles are starved of oxygen and patients experience a crash the day after exercise. In the brain, the same faulty cells let blood flow drop and leak, bringing on brain fog and dizziness. In the gut, they weaken the lining, allowing bits of bacteria to slip into the bloodstream and trigger more inflammation. Because blood vessels reach every corner of the body, even scattered patches of these 'zombie' cells found in the blood vessels can create the mix of symptoms seen in long-COVID and ME/CFS. Immune exhaustion locks in the damage Some parts of the immune system kill senescent cells. They are natural-killer cells, macrophages and complement proteins, which are immune molecules capable of tagging and killing pathogens. But long-COVID and ME/CFS frequently have impaired natural-killer cell function, sluggish macrophages and complement dysfunction. Senescent endothelial cells may also send out a chemical signal to repel immune attack. So the 'zombie cells' actively evade the immune system. This creates a self-sustaining loop of vascular and immune dysfunction, where senescent endothelial cells persist. In a healthy person with an optimally functioning immune system, these senescent endothelial cells will normally be cleared. But there is significant immune dysfunction in ME/CFS and long-COVID, and this may enable the 'zombie cells' to survive and the disease to progress. Where the research goes next There is a registered clinical trial in the US that is investigating senescence in long-COVID. Our consortium is testing new ways to spot signs of ageing in the cells that line our blood vessels. First, we expose healthy endothelial cells in the lab to blood from patients to see whether it pushes the cells into a senescent, or 'zombie,' state. At the same time, we are trialling non‑invasive imaging and fluorescent probes that could one day reveal these ageing cells inside the body. In selected cases, tissue biopsies may later confirm what the scans show. Together, these approaches aim to pinpoint how substances circulating in the blood drive cellular ageing and how that, in turn, fuels disease. Our aim is simple: find these ageing endothelial cells in real patients. Pinpointing them will inform the next round of clinical trials and open the door to therapies that target senescent cells directly, offering a route to healthier blood vessels and, ultimately, lighter disease loads.

The FDA must crack down on dangerous knockoff weight-loss drugs
For the first time, there is real hope in the fight against obesity. New data from the Centers for Disease Control and Prevention's National Center for Health Statistics shows that adult obesity rates in the U.S. may finally be flatlining after annual increases since at least 2011. Obesity has long been understood to be the second leading cause of preventable death in America. Neither negative cultural attitudes about weight nor government messaging campaigns about diets have helped curb it. Yet like most insurmountable problems, we are innovating our way out of it. Experts believe a significant part of recent progress is due to powerful new medications such as Ozempic and Mounjaro, known as GLP-1 drugs. But just as these drugs are changing lives, a dangerous shadow market is growing alongside them. Compounded versions, which are copies of the original drugs made in smaller pharmacies, are flooding websites, med spas and clinics. These versions are often cheaper and easier to get than the real thing. They are also frequently untested, poorly regulated and, in many cases, illegal. The FDA has received more than 500 reports of serious side effects tied to compounded semaglutide and tirzepatide, the active ingredients in Ozempic and Mounjaro. Some patients have landed in the hospital after taking the wrong dose. That is not surprising when you consider that many of these vials come without proper labels or instructions. In 2023 alone, poison control centers received nearly 3,000 semaglutide-related calls, a huge jump from previous years. Many of those cases involved compounded or mislabeled versions of the medication. There are also serious concerns about what is actually in these products. The FDA has warned that some pharmacies are using different chemical forms of semaglutide, called salt forms, that are not approved for use and may not be safe. In April 2025, the agency seized counterfeit Ozempic from the U.S. supply chain after discovering that some vials contained the wrong ingredients or were contaminated with dangerous bacteria. These are not technical violations. They are real risks to people's health. During earlier shortages, compounding was allowed under special circumstances. But those shortages have ended, and the FDA has ordered most pharmacies to stop making these versions. Despite that, many continue to operate in legal gray zones or offer these drugs online. The harm does not stop with safety concerns. This trend also threatens future breakthroughs in obesity care. Companies like Novo Nordisk and Eli Lilly spent years and billions of dollars to develop these treatments. Now, they and others are working on new and even more effective drugs. When unapproved copies flood the market, it becomes harder to fund innovation. If investors cannot count on fair returns, the next generation of such medications may not make it out of the lab. Perhaps the biggest risk is to public trust. When someone has a bad experience with a fake or contaminated version, they may begin to doubt all weight loss innovations. That fear can ripple through the health system, making insurers and doctors more hesitant to support treatments that are helping with the genuine public health emergency of obesity. None of this means that compounding should disappear. It has a place when patients have specific medical needs that cannot be met by the approved versions, such as allergies or special dosing requirements. But what is happening now is not about rare exceptions. The FDA should continue cracking down on compounders that use unapproved ingredients or sell mislabeled products disguised as 'research chemicals.' At the same time, insurers and lawmakers need to make the real thing more affordable by removing middlemen such as pharmacy benefit managers. No one should have to choose between risking their health and going broke. We are finally making progress against a disease that affects nearly half the country and has stumped policymakers and advocates for decades. But progress is fragile. Unregulated versions of GLP-1s cannot be allowed to dominate the market. We risk undoing the progress reported by the CDC in the fight against obesity, and if we get this right, the trend could be reversed. That means longer lives for more people, lived in dignity and to the fullest.
