Quademic 2025: Hospitals in the United States are dealing with a surge in patients admission, the reason is the quademic it is dealing with at this moment. This has led to an influx of patients. It is all caused by seasonal infections, including common flu, Covid-19, and respiratory syncytial virus (RSV) that dominate the winter season in the US. This year, norovirus also joined the list, which has further increased the load on the healthcare.

The healthcare company founded in academics M Health Fairview, confirmed that their hospitals are overflowing due to the quademic.

Is US able to cope with Quademic 2025?

The hospitals of M Health Fairview's volume is up by 30% and as a results, patients are being treated in the hallways and in alternative care areas. There is also a longer wait time and shortages for resources that are required to treat these emergencies. This has also impacted other life-threatening emergencies like heart attacks and strokes, as the healthcare resources and caregivers are occupied with the surge in seasonal cases.

What are these quademic infections?

Common cold and flu: The common cold and influenza (flu) are perhaps the most well-known illnesses that peak during the fall. As temperatures drop and humidity levels fluctuate, viruses that cause colds and the flu become more active. The flu, in particular, can be more severe than a common cold, leading to complications such as pneumonia, especially in vulnerable populations like the elderly and those with pre-existing health conditions. Symptoms include a runny nose, sore throat, coughing, fever, and body aches.

Covid-19: As per the World Health Organization, Coronavirus disease or COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with this virus will experience mild to moderate respiratory illness and recover without requiring special treatment, However, there could be some cases of seriously ill patients who may require medical attention. It is also because of the other existing medical conditions like cardiovascular diseases, diabetes, chronic respiratory diseases, cancers, or older age.

The best way to protect against this virus is by following social isolation form those who are infected, using mask to prevent droplets from infecting others when you cough or sneeze and to wash your hands for 20 seconds frequently.

RSV or Respiratory Syncytial Virus: As per the Centers of Diseases Control and Prevention (CDC), RSV is a common respiratory virus that infects nose, throat and lungs. Though symptoms are similar to the viruses like flu or COVID-19, the disease in itself is different. It also peaks during the winter season, especially between December and January.

However, the main difference between RSV and other respiratory illness, above mentioned is that RSV can cause pneumonia or bronchiolitis, especially for those who are over the age of 50 or with an existing heart or lung disease.

Norovirus: It is a number 1 cause of foodborne illness in the US and this happens when virus gets into the food and then it accidentally enters your mouth. These particles are from faeces or vomit from infected people, or can be transmitted via contaminated food and water. It could also spread by touching unclean surfaces like door handles or cutlery.

For most people, having norovirus is unpleasant, but mild and recovery could be made in 1 to 2 days. However, it could be more serious for babies, older people and anyone with any existing health condition.

The Cyclospora outbreak that has spread across the US for more than three months has turned deadly, with Michigan—the hardest-hit state—reporting the country's first two deaths linked to the diarrhea-causing parasite.

According to the Michigan Department of Health and Human Services (MDHHS), both individuals had significant underlying health conditions.

"Two deaths have been identified as part of the cyclosporiasis outbreak affecting Michigan. According to medical records, both individuals had significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration," the department said.

Health officials stressed that deaths from cyclosporiasis are rare, as the infection is generally not life-threatening. Michigan has reported 11,234 cases, including 193 hospitalizations.

The US Centers for Disease Control and Prevention (CDC) also confirmed the two outbreak-related deaths in Michigan. As of its July 28 update, the agency has recorded 6,707 laboratory-confirmed cases across 45 states since May 1, along with more than 11,500 suspected cases—primarily in Michigan and Ohio—that are yet to be laboratory confirmed. The outbreak has resulted in 423 hospitalizations.

FDA Links Outbreak to Recalled Iceberg Lettuce

The US Food and Drug Administration (FDA) has linked part of the outbreak to iceberg lettuce supplied by Taylor Farms de Mexico. The company voluntarily recalled affected products on July 17 and said it will no longer source iceberg lettuce from central Mexico for the rest of the growing season.

The recalled lettuce has been linked to illnesses in Indiana, Kentucky, Michigan, Ohio, and West Virginia. Separately, the CDC, FDA, and state health officials are investigating another Cyclospora outbreak linked to iceberg lettuce in nine states, which has sickened at least 1,947 people and hospitalized 98.

Officials are also investigating whether parsley and cilantro may be linked to the outbreak.

What Is Cyclospora?

Cyclospora is a parasite that infects the intestines and is usually spread through contaminated food or water.

Symptoms include:

• Frequent watery diarrhea
• Abdominal cramps
• Bloating
• Nausea
• Excessive gas
• Low-grade fever
• Loss of appetite
• Weight loss

What Should You Do If You Think You Have Cyclosporiasis?

Most infections are mild and resolve without treatment. However, the illness can be prolonged or severe in people with weakened immune systems, who may require antibiotic treatment.

If you develop symptoms:

• See a healthcare provider and request a stool test to confirm a Cyclospora infection.
• Drink plenty of fluids to prevent dehydration caused by diarrhea.
• Because diarrhea can have many causes, getting the right diagnosis is important, as cyclosporiasis is treatable with a specific antibiotic.
• Seek immediate medical attention if you have severe diarrhea, feel dizzy when standing, or have a rapid heartbeat, as these may be signs of serious dehydration.

How Is It Diagnosed and Treated?

Doctors diagnose cyclosporiasis with a stool test that detects the Cyclospora parasite shed in stool.

Although some mild infections may resolve on their own, confirmed cases should be treated with antibiotics. The recommended treatment is the antibiotic trimethoprim/sulfamethoxazole (TMP-SMX).

Your doctor may also recommend:

• Medicines to relieve diarrhea, if appropriate.
• Oral or intravenous fluids to prevent or treat dehydration.

How To Reduce Your Risk

• Check whether recently purchased iceberg lettuce was sourced from Taylor Farms de Mexico, Guanajuato.

• The recall includes:

1. 12-ounce and 24-ounce Iceberg Salad with best-by dates July 18–August 3
2. 8-ounce and 16-ounce Shredded Lettuce with best-by dates July 18–August 3

• Discard or return any recalled products. An additional 33 recalled products were supplied to restaurants and are unlikely to be in home refrigerators.
• No other lettuce varieties, including romaine and butter lettuce, have been linked to the outbreak.
• Avoid eating recalled shredded iceberg lettuce.
• Wash all fresh fruits and vegetables thoroughly under running water, even if labeled pre-washed.
• Choose whole heads of lettuce over bagged greens when possible. Remove the outer leaves and wash the inner leaves thoroughly.
• Cook produce whenever possible, as heat is the most effective way to kill Cyclospora.
• Follow safe food-handling practices and stay updated on food recalls.

Tiny plastic particles may be making their way into one of the body's most protected organs, the brain, according to new research. This has raised concerns about the long-term health effects of microplastic exposure, particularly on brain health.

In a study published in Nature Medicine, researchers found that microplastics and nanoplastics were present in brain tissue, with significantly higher concentrations than in liver and kidneys.

One of the most important findings is that these particles can cross the blood-brain barrier, a protective shield that normally blocks harmful substances from entering the brain.

The researchers analysed brain tissue samples collected over several years and observed that they contained seven to 30 times more plastic particles than other organs.

They also found an increase in brain plastic concentrations in more recent samples, reflecting the growing burden of plastic pollution worldwide in the last few years.

"Our data suggest a trend of increasing concentrations of micro- and nanoplastics in the brain," the study authors wrote. They stressed that the findings do not prove these particles cause disease.

Could Microplastic Exposure Increase Dementia Risk?

The researchers also reported higher concentrations of plastic particles in brain tissue from people diagnosed with dementia.

However, they cautioned that the study only identified an association and cannot determine whether microplastics contribute to dementia or whether brains diseased with dementia simply accumulate more particles.

Scientists are still trying to understand how these particles do harm once they reach the brain. Proposed theories include triggering inflammation, disrupting communication between nerve cells, or affecting blood flow, but none have yet been confirmed in humans.

How Can Microplastics Get Into The Brain?

Since nanoplastics are extremely small, researchers believe some may pass through the blood-brain barrier and become trapped in brain tissue.

The study found polyethylene, commonly used in food packaging and plastic bottles, was the most abundant type detected in the brain tissue.

Scientists emphasise that it is too early to conclude that microplastics directly damage the human brain.

"The findings are concerning, but they should not be interpreted as proof that microplastics cause neurological disease," the researchers emphasised. More studies are needed to determine whether the particles themselves are harmful or simply markers of environmental exposure.

How To Reduce Exposure To Microplastics?

While eliminating exposure entirely is nearly impossible, experts recommend practical steps that may lower intake:

• Avoid heating food in plastic containers.
• Choose glass or stainless steel for food and water storage when possible.
• Reduce consumption of heavily packaged and ultra-processed foods.
• Improve indoor ventilation and reduce household dust, another potential source of airborne microplastics.

The study adds to mounting evidence that microplastics are no longer just an environmental issue. They are increasingly being detected throughout the human body, including the blood, lungs, placenta and now the brain.

A new study by the US Centers for Disease Control and Prevention (CDC) has found that nearly one in three patients who were hospitalised were diagnosed with invasive mould disease (IMD) died during their hospital stay.

The findings highlighted the urgent need for better surveillance, hygiene, early diagnosis, and greater awareness among healthcare professionals.

The findings come from the surveillance study of invasive mould infections conducted by the CDC across four hospitals in Atlanta and Georgia, between 2020 and 2024.

What Did The Study Find?

Researchers identified 499 confirmed cases of invasive mould disease during the five-year study period. Around 33% of these patients died while hospitalised, while the overall 90-day mortality rate reached 45%.

Nearly half of the patients needed intensive care, and about 50% needed ventilation, highlighting just how severe these infections can turn.

Patients who had a recent or current COVID-19 infection were found to be even worse. Their 90-day mortality rate was 66%, compared with 41% among patients without COVID-19.

"Our findings demonstrate that invasive mold disease is associated with substantial illness and death," the CDC researchers wrote, adding that active surveillance can help improve understanding of how common these infections are and guide prevention efforts.

What Is Invasive Mould Disease?

Unlike the mould that grows on damp walls or spoiled food, invasive mould disease occurs when fungal spores enter the body through the lungs, wounds, or contaminated medical equipment and spread into deep tissues, blood vessels, or organs.

The infections are most commonly caused by fungi such as Aspergillus, Mucorales, Fusarium, and Scedosporium. Once inside the body, they can rapidly become life-threatening if not diagnosed and treated early.

Who Is Most At Risk?

The disease rarely affects healthy individuals. Instead, it primarily targets people whose immune systems are already weakened, including:

• Cancer patients undergoing chemotherapy
• Organ transplant recipients
• People taking long-term steroids or immunosuppressive drugs
• Patients in intensive care units
• Individuals recovering from severe COVID-19
• Older adults with multiple illnesses

Why Experts Are Concerned

One of the biggest challenges is that invasive mould disease is not a nationally reportable disease in the United States, meaning health authorities do not routinely collect nationwide data on cases. Researchers believe the actual burden may therefore be underestimated.

The CDC authors noted that active surveillance is essential to estimate disease incidence, identify outbreaks, and improve patient outcomes. They also highlighted that patients with COVID-19 experienced significantly more severe disease, suggesting clinicians should remain vigilant for fungal complications in critically ill patients.

Outside experts have also warned that factors such as climate change, extreme weather events, an ageing population, and rising antifungal drug resistance could contribute to an increase in serious fungal infections in the coming years.

Although invasive mould infections remain relatively uncommon, the study shows they carry an alarmingly high risk of severe illness and death among vulnerable patients. Researchers say increasing awareness, recognising symptoms early, improving hospital surveillance, and developing faster diagnostic tools could help identify infections sooner and improve survival.
