There's been an alarming increase of respiratory and gastrointestinal viruses in the United States lately, causing anxiety about a so-called "quad-demic". According to surveillance reports, influenza, COVID-19, RSV and norovirus are at very high levels everywhere. While the surge aligns with patterns typical for this season, several epidemiologists view simultaneous infections of such proportions to pose risks not only to individual healthcare but public health.

The incidence of the quad-demic should vary with seasonal patterns, vaccination rates, and public health interventions. Each virus alone is relatively easy to manage; however, the effect of all together could lead to overburdening of health care facilities and increase risks for those at higher risk. Continuing surveillance, early testing, and proactive prevention measures will play an important role in the control of these infections going forward.

While the term "quad-demic" sounds daunting, it must be taken into perspective. For years, we have had all these viruses together, and we have the capabilities to mitigate some of the risk. Vaccination, proper hygiene and using common sense helps individuals get through the season unscathed. Is the quad-demic a permanent fixture or just another seasonal wave? Let's break this down.

What is the Quad-demic?

Typically, flu, COVID-19, and RSV have been the primary culprits behind seasonal respiratory infections. However, norovirus, a highly contagious stomach bug, has emerged as a fourth significant player, inducing fears of a more severe and widespread viral outbreak. According to the Centers for Disease Control and Prevention (CDC), the U.S. recorded nearly 500 norovirus outbreaks between August and December 2023, a substantial rise from the previous year’s numbers.

While the term "quad-demic" may sound ominous, the seriousness and consequences of such infections should be weighed in light of the U.S. healthcare system's experience with managing viral surges since the start of the COVID-19 pandemic.

1. Influenza (Flu)

Flu continues to be one of the most common and alarming seasonal illnesses. In the period spanning from 2023 to 2024, there were approximately 40 million cases of flu, and thousands of hospitalizations along with reported 47 deaths have been reported this season. Flu symptoms include fever, chills, cough, sore throat, muscle pain, and fatigue, with most recovering within a week or two but risky factors for severe illness effects occur in young children, elderly, and people with chronic conditions.

2. Covid-19

Despite its reduction from the first pandemic peak, COVID-19 is still rampant. The CDC estimates that alone between October and December 2023, there were between 2.7 and 5 million cases in the U.S. Hospitalization has increased by cities such as Los Angeles, Chicago, and New York. Symptoms are closely similar to the flu, fever, cough, and fatigue but uniquely presents in some cases as loss of taste and smell.

3. RSV

RSV is the most common cause of lower respiratory infections in infants, older adults, and immunocompromised individuals. While RSV peaked late in 2023 and early 2024, it continues to be a threat because it can lead to bronchiolitis and pneumonia. It is very similar to the common cold, presenting with symptoms such as congestion, runny nose, coughing, and fever, which can make it difficult to differentiate from flu or COVID-19 without testing.

4. Norovirus

Norovirus, also called the "stomach flu," is a highly contagious infection of the gastrointestinal tract, not a respiratory virus. It transmits quickly from contaminated food and water and contact with contaminated surfaces, causing such symptoms as diarrhea, vomiting, nausea, and stomach pain. Cases have shot up, the CDC said Monday, with reports of outbreaks surging compared with last year.

Is There a Challenge In Diagnosis Due to Overlapping Symptoms?

The greatest challenge during the quad-demic is how the four viruses are alike and thus make identification very hard with no testing applied. Most cases present symptoms common to all viruses: fever, tiredness, body pains, and respiratory, which includes coughing and congestions for influenza, COVID-19, and RSV; the other would be norovirus symptoms as nausea and vomiting can appear even in extreme influenza and COVID-19. This overlap increases the risk of misdiagnosis and delayed treatment, hence the need for early testing and proper medical guidance.

Effective Prevention Strategies That Work

The best defense against these viruses is a combination of vaccines, hygiene, and lifestyle precautions. While lifestyle modifications are highlighted as part of the constant need to eat healthy, ensure daily movement and drinking adequate amount of fluids. There is a sure short two preventive strategies that are effective:

Vaccination

• Flu vaccine: Annual flu shots reduce the severity of infection, allergic flare ups and hospitalizations.
• COVID-19 vaccine: Though COVID-19 cases have declined, vaccination remains critical in preventing severe outcomes.
• RSV vaccine: Available for those aged 60 years and older, especially those with underlying conditions.
• Norovirus vaccine: No vaccine is yet available, but mRNA vaccine research is in progress.

Hygiene and Sanitation

• Washing hands frequently with soap and water for at least 20 seconds, especially after public exposure.
• Disinfect frequently touched surfaces regularly, use sanitiser when outside.
• Avoid close contact with infected people and wear masks.

Do You Need To Wear A Mask All The Time?

While debates on masked wear continue on, experts on mask-wear affirm that this does not only have a historical precedent but works towards reducing airborne viruses spreading within the environments. Hospitals, though, ensure masking in key sections of themselves. Publicized mask-wear remains a discretion, though massing indoors still goes a longer way in cases like peak flu seasons.

If you notice the symptoms of these viruses, then it's best to be confined at home and avoid having face-to-face interaction with others and seek immediate attention from your physician if your condition worsens. Quarantining for some days can decrease the spread of infection.

As we move into the first half of 2025 and beyond, staying informed and proactive is the best strategy for maintaining health and avoiding unnecessary panic. The key takeaway? Stay vigilant, but don’t be alarmed—these viruses are here, but so are the means to fight them.

American model and actress Paris Jackson has opened up about battling depression and dealing with suicide attempts.

In a recent podcast, Jackson revealed that she underwent electroconvulsive therapy (ECT), which she said helped her. While describing the treatment as “painful,” she said it was not a “barbaric” experience.

The 28-year-old said she underwent nine ECT sessions over three weeks, with each session performed under general anesthesia.

Paris Jackson Describes Her ECT Experience

Jackson recalled that she had to replace the metal from her facial piercings with plastic earrings before undergoing the treatment.

“You go in, you get your hospital gown, they knock you out, strap you down, put a bite guard on your mouth [and] electrocute you,” she said while describing the procedure.

“It helps with the neuroplasticity in your brain,” Paris continued. “If I’m not mistaken, it’s still the leading most effective form of depression treatment.”

She said the first couple of sessions were “painful” and that she experienced significant side effects.

“The first time I woke up, and it was the most sharp pain I have ever experienced inside of my head,” she recalled, describing it as soreness after being electrocuted. She also said there were days when she felt “completely not in my head at all.”

Jackson Tried Several Treatments Before ECT

Jackson has previously opened up about her suicide attempts, describing her experience of self-hatred, low self-esteem and feelings that she was not worthy of living.

She has also spoken about engaging in behaviours she felt were inappropriate for her age and trying to grow up too quickly.

Before undergoing ECT, Jackson said she had tried “everything,” including multiple medications and treatment at “five different institutions.”

She also tried CBD, dialectical behavioral therapy (DBT) and eye movement desensitization and reprocessing (EMDR).

She recalled trying different forms of therapy, saying, “I had talked to the empty chair, held the pillow, beat the things with bats while screaming.”

Jackson also underwent transcranial magnetic stimulation (TMS), which she said “helped a little bit with [her] OCD but had no effect on [her] depression.”

Her psychiatrist subsequently brought up ECT as another treatment option.

Jackson now focuses on “holistic health” to make her recovery “sustainable” and sees a behavioral specialist for her OCD.

What Is Electroconvulsive Therapy?

Electroconvulsive therapy (ECT) is a procedure performed under general anesthesia. During the treatment, small electric currents are passed through the brain, intentionally triggering a brief seizure.

According to Mayo Clinic, ECT appears to cause changes in brain chemistry that can quickly improve symptoms of certain mental health conditions.

When May ECT Be Recommended?

ECT is known to rapidly improve severe symptoms of several mental health conditions. It may be used for:

• Severe depression with suicide risk
• Treatment-resistant depression
• Severe mania
• Catatonia
• Agitation and aggression in people with dementia

ECT may be considered when a person cannot tolerate medicines or has not found relief from other forms of treatment.

Can ECT Reduce Suicide Risk?

ECT can be used for severe depression accompanied by suicide risk and is known for rapidly improving severe depressive symptoms.

However, ECT is not a universal treatment for suicidal thoughts or behaviour. Its use depends on the individual's condition, medical history and response to other treatments, and it is administered under medical supervision.

ECT Side Effects

Jackson also spoke about amnesia as one of the side effects of ECT.

“Friends visited me, and I don’t remember even seeing them [even though] I have evidence. … I don’t remember the conversations,” she said.

Memory problems are a known side effect of ECT and can affect a person's ability to recall events around the time of treatment.

Amid a rise in infectious diseases, particularly measles, a new report from the US Centers for Disease Control and Prevention (CDC) shows that kindergarten vaccination rates declined during the 2025-26 school year.

The report also shows an increase in vaccine exemptions among children.

Kindergarten Vaccination Rates Decline

The CDC report showed that coverage for key childhood vaccines, including measles, mumps and rubella (MMR), diphtheria, tetanus, and pertussis (DTaP), polio and varicella, decreased in more than half of US states.

• DTaP vaccine coverage: 92%
• MMR vaccine coverage: 92.4%
• Polio vaccine coverage: 92.4%

The CDC, in a statement, said the data showed a 0.1% decline in vaccination coverage among children entering kindergarten.

Further, the data showed that about 280,000 kindergartners attended school without documentation of completing the MMR vaccine series during the 2025-26 school year.

Vaccine Exemptions Rise

Exemptions from one or more vaccines among US kindergartners increased to 4.2% during the 2025-26 school year, up from 3.6% in the previous school year, the CDC said.

Exemptions rose in 41 states and Washington, D.C. Of these, 24 states reported exemption rates exceeding 5%. The number of kindergartners exempt from one or more vaccines was about 155,000.

Measles Cases Hit 35-Year High

The decline in vaccination rates comes amid continued debate over the Donald Trump administration's vaccine policies and controversial changes to childhood vaccination recommendations.

Importantly, the period has seen measles cases reach levels not seen in more than three decades, threatening the US's measles elimination status.

With 38 new outbreaks reported in 2026, there have been 2,566 confirmed measles cases reported in the US as of August 13.

In comparison, a total of 2,289 confirmed measles cases were reported in the US during the full year of 2025. There were 48 outbreaks reported in 2025.

Children Account for Nearly Half of Measles Cases

In 2026, nearly 20% of measles cases, or 497 cases, were reported among children under 5 years of age. Of these, 10% were hospitalized due to the highly infectious disease. The highest number of cases was reported among children aged 5 to 19 years, with 1,222 cases, or 48%, followed by adults aged over 20, with 835 cases, or 33%.

In total, 93% of measles cases occurred among people without vaccination, and 7% were hospitalized.

AAP Warns About Falling Vaccination Rates

According to public health officials, overall measles vaccination rates should remain above 95% to maintain herd immunity.

"When it comes to vaccination rates, however, anything less than achieving an A+ grade is not good enough. For some diseases like measles, even a small decrease in vaccination rates can lead to more outbreaks of disease because community immunity requires over 95% of susceptible individuals to be immunized," said Dr. Andrew Racine, President of the American Academy of Pediatrics (AAP), in a statement.

He added, "This risk is real: The United States is experiencing a 35-year high for measles cases as federal officials continue to elevate misleading and disproven information about vaccines, inserting unnecessary fear and confusion into families’ decision-making. And we are seeing the results. More than a quarter of a million children started kindergarten last year without protection from the MMR vaccine."

Meanwhile, Trump signed an executive order last week calling for fewer childhood vaccinations by limiting the inoculation schedule to 11 immunizations. The order also recommended splitting the MMR vaccine into three shots taken at separate visits.

What began as what appeared to be an ordinary influenza infection turned into a medical emergency for an otherwise healthy eight-year-old girl in Aurora, Ontario.

Leanne Gorin developed fulminant myocarditis, a rare and severe form of heart inflammation triggered by influenza B, within just 48 hours of becoming ill.

She spent five weeks at SickKids Hospital and underwent multiple major procedures, including a 10-hour open-heart operation, before dying on July 23, a day after her eighth birthday.

Her mother, Ilona, told local media that Leanne had been a perfectly healthy child and initially showed few warning signs beyond a 40°C (104°F) fever.

“I had a perfectly healthy daughter,” she said, describing the complication as extraordinarily rare.

Leanne's case highlights the severity of myocarditis - a complication of influenza that parents may rarely hear about.

What Is Myocarditis?

In many cases, myocarditis can be mild or even go unnoticed. But in severe cases, inflammation can dramatically reduce the heart's ability to pump blood.

The most serious form is called fulminant myocarditis. It can cause rapid heart failure, dangerous abnormal heart rhythms and cardiogenic shock, where the heart can no longer pump enough blood to support the body's organs.

How Can The Flu Affect The Heart?

Influenza primarily infects the respiratory system, but the infection can trigger ripple effects throughout the body.

Researchers believe myocarditis may occur through a combination of direct viral injury and an excessive or abnormal immune response to the infection. The resulting inflammation can damage heart muscle cells and interfere with the heart's functions.

Why Is Fulminant Myocarditis So Dangerous?

As the heart becomes inflamed and weakened, it may no longer pump enough blood to the brain, kidneys and other organs. Patients can develop very low blood pressure, abnormal heart rhythms and severe heart failure. The condition can deteriorate pretty quickly.

In Leanne's case, her condition became critical within 48 hours. She eventually needed major cardiac surgery and prolonged hospitalisation.

What Symptoms Should Parents Watch For?

The tricky part is that early symptoms can overlap with influenza itself. Parents should seek medical attention if a child with flu develops symptoms that suggest the heart may be struggling, including:

• Chest pain or pressure
• Difficulty breathing or shortness of breath
• A racing or irregular heartbeat
• Fainting or severe dizziness
• Extreme or unusual weakness
• Sudden difficulty exercising or walking
• Pale, greyish or bluish skin
• Swelling

A high fever alone does not mean a child has myocarditis. Influenza commonly causes high fever, particularly in children.

If new or unusually severe symptoms appear, like breathing problems, chest symptoms, fainting or a noticeably abnormal heartbeat, medical attention must be sought.

Doctors can investigate suspected myocarditis using tests such as an ECG, blood tests, echocardiogram and, in some cases, cardiac MRI. Treatment depends on how severely the heart has been affected.
