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.

Finance Minister Nirmala Sitharaman has announced a surprising tax reduction for India's fishers and marine industry, and experts say it is good news for you too.

Until now, fish caught by Indian vessels beyond territorial waters and brought back to the country for mass consumption has been treated as import, attracting customs duties and integrated goods and services tax (GST).

The combined tax burden raises costs and compliance issues, which discouraged people from deep-sea and exclusive economic zone (EEZ) fishing as well as

However, during her Union Budget 2026 presentation, Sitharaman proposed that fish caught in the EEZ and high seas by Indian fishing vessels are treated as duty-free when brought into Indian ports and treated as exports when landed at foreign ports.

This means that the market availability for Omega-3 packed fishes including salmon, mackerel, tuna, herring and sardines will significantly increase as their existing steep prices see a tremendous fall.

What Are Fish Oil Omega-3s?

Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.

These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Since many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.

Although the body can convert another type of omega-3, alpha-linolenic acid (ALA), into EPA and DHA, this process is not highly efficient. As a result, fish oil supplements may provide a convenient way to ensure optimal levels of omega-3s.

Some popular sources of Omega-3 include:

• Salmon
• Cod Liver Oil
• Algae Oil
• Oysters
• Nuts and seeds, such as flaxseeds, chia seeds, and walnuts
• Plant oils, such as flaxseed oil, soybean oil, and canola oil
• Fortified foods, such as eggs, yogurt, juices, milk, etc.

How Omega-3s Improves Brain Health

EPA and DHA are essential for maintaining brain function throughout life. These fatty acids are abundant in the brain's cell membranes, helping to preserve cell health and facilitate communication between brain cells.

Research has shown that a lack of omega-3 can lead to cognitive impairments. In animal studies, diets deficient in omega-3s resulted in reduced DHA levels in the brain, leading to deficits in learning and memory. In older adults, lower DHA levels have been linked to a smaller brain size, which may indicate accelerated brain ageing.

Maintaining sufficient levels of omega-3s can help support cognitive function and may reduce the risk of age-related brain decline.

The optimal dosage varies, but research suggests that 1,000–2,000 mg of omega-3 fatty acids from fish oil daily is a good starting point. People with depression should look for supplements with higher EPA content. It is pertinent to note that people should consult health experts before starting fish oil supplementation.

Import Duty Decreased On Cancer Drugs

These imported, specialized cancer treatments, particularly targeted therapies and monoclonal antibodies, often cost thousands, placing a massive financial burden on patients, leading to lifelong debts.

In this year's Union Budget, Sitharaman also proposed reducing import duty tax on 17 cancer drugs and seven medicines for rare diseases, which will in turn, help patients seek proper care on a timely basis.

Deshmukh commented: "India is witnessing a steady and alarming rise in cancer cases, where late detection, prolonged treatment and high medicine costs often lead to preventable complications and loss of life. Against this backdrop, the Union Budget’s decision to remove customs duty on 17 cancer drugs and 7 medicines for rare diseases stands out as a truly progressive and patient-first measure.

"Affordability remains one of the biggest hurdles in cancer care, forcing many families to delay or discontinue treatment. By reducing import duties, this move has the potential to significantly lower the cost of advanced and targeted therapies, making them accessible to a larger section of patients."

Experts are cautioning US of a potential Nipah virus outbreak, especially through international travels. Countries across Asia have already started airport health screenings. Thailand has geared up as it receives a high number of travelers from Kolkata, where the two cases of Nipah virus were detected.

Experts Reveal Risks Of Nipah Virus Outbreak: What Are They Saying?

Dr Krutika Kupalli, a Texas-based expert who formerly also worked with the World Health Organization (WHO), told The Daily Mail that the possibility of Nipah virus outbreak is 'absolutely' something the Centers for Disease Control and Prevention (CDC) should be 'closely monitoring'.

“Nipah virus is a high-consequence pathogen, and even small, apparently contained outbreaks warrant careful surveillance, information sharing, and preparedness. Outbreaks like this also underscore the importance of strong relationships with global partners, particularly the WHO, [which] plays a central role in coordinating outbreak response and sharing timely, on-the-ground information," she said.

A CDC spokesperson told The Daily Mail that the agency is in 'close contact' with authorities in India. "CDC is monitoring the situation and stands ready to assist as needed."

Experts Reveal Risks Of Nipah Virus Outbreak: What Is Happening In India?

Nipah virus outbreak reported in West Bengal, India started with the cases of two nurses, one of whom has now been discharged.

As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.

In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.

Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

Nipah virus is infectious and can spread from animals like bats and pigs to humans through bodily fluids or contaminated food. It can also pass between people through close contact, especially in caregiving settings. While it can spread via respiratory droplets in enclosed spaces, it is not considered highly airborne and usually requires close, prolonged contact for transmission. Common routes include direct exposure to infected animals or their fluids, consuming contaminated fruits or date palm sap, and contact with bodily fluids such as saliva, urine, or blood from an infected person.

The American Red Cross reported a severe shortage of blood that has affected Tri-City area hospitals. In the last month, there has been a 35% drop in blood supply. The 'Code Red' blood shortage in Washington created a critical situation with hospitals requesting for blood. The drop is also noted due to the winter weather that has affected donation drive.

Red Cross Faces Blood Shortage: How Does Weather Influence Blood Bank?

Reports note that during the winter season, blood supply becomes challenging, though its demand may increase due to illness and severe weather conditions. However, the same factors lead to fewer donation drives that leads to critical shortage. According to Red Cross reports, more than 550 blood drives have been canceled since January 21. This has resulted in over 15,000 uncollected blood and platelet donation.

The shortage has severely impacted the availability of blood for trauma victims, cancer patients and those who require emergency surgeries. During such situation, volunteer donors play an essential role.

Diana Heilman, supervisor at the Kennewick Red Cross Fixed Site, said, "octors may face difficult decisions during a blood shortage, such as who can safely receive the products and treatments, and they will potentially have to wait because there simply isn't enough blood available."

Red Cross Faces Blood Shortage: What Is Affected?

• The Kennewick Red Cross identified a dire need of Type O blood, both positive and negative
• A negative
• B negative
• Platelets

Type O is a universal donor, while Type O positive is the most commonly transfused blood type. A negative blood type is found in only 6% of the population, and B negative is less than 2%.

Red Cross also announced a $20 e-gift card for those who donate between January 26 to February 28, as incentive.
