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.

Pharmacies across Britain are reporting serious shortages of a widely used medication, raising concerns that patients could face a higher risk of heart attacks and strokes. Pharmacists have described the situation as “madness,” warning that current NHS prescribing rules are stopping them from switching patients to suitable blood-thinning alternatives when aspirin is unavailable.

While aspirin is commonly taken as a pain reliever, it is also prescribed as a blood thinner. Around one-third of women and nearly 45 percent of men over the age of 65 rely on it as part of their daily medication routine.

Aspirin Shortage Hits UK Pharmacies

A new survey conducted by the National Pharmacy Association (NPA), involving 540 community pharmacies across the UK, found that 86 percent are currently unable to supply aspirin. The shortage appears to be most severe for the low-dose 75mg tablets, although pharmacists report that all strengths are affected. Several pharmacies have also stopped selling aspirin over the counter due to limited stock.

As per The Independent, Olivier Picard, chair of the NPA, said pharmacists are deeply concerned about their inability to order sufficient supplies and the impact this could have on patients who depend on the drug. Low-dose aspirin, particularly the 75mg dose, is commonly prescribed for its antiplatelet effect, which helps prevent the formation of blood clots and lowers the risk of heart attacks and strokes.

Who Is Prescribed Aspirin?

Doctors often prescribe aspirin to people who have previously suffered a heart attack or stroke, experienced a transient ischaemic attack, or have conditions such as angina or peripheral arterial disease (PAD). It may also be recommended after certain types of surgery to reduce the risk of clotting.

Aspirin: Why Is UK Facing A Shortage?

The NPA is urging the government to reform prescribing regulations that currently prevent pharmacists from offering safe alternatives when the prescribed medicine is unavailable. Mr Picard said pharmacists have long argued for the ability to make appropriate substitutions in these situations.

He added that forcing patients to return to their GP for a revised prescription when an alternative drug is already available is not only frustrating but potentially dangerous. Delays or interruptions in treatment could lead patients to miss vital medication, increasing risks to their health.

Aspirin Added To Export Ban List

In response to the ongoing issue, the Government has added aspirin to its export ban list in an attempt to safeguard supplies for patients in the UK.

The NPA also said pharmacists have been forced to tightly ration the remaining stock, prioritising patients with the most urgent heart conditions or those requiring emergency prescriptions.

According to the Independent Pharmacies Association, international manufacturing delays and wider supply chain disruptions are key reasons behind the shortage. The organisation also pointed to low prices negotiated by the NHS, which can make the UK a lower priority for pharmaceutical manufacturers when stock is limited.

Dr Leyla Hannbeck, chief executive of the Independent Pharmacies Association, said it is deeply concerning to see shortages affecting essential medicines such as aspirin and blood pressure treatments. She explained that while manufacturing delays play a role, pharmacies are also struggling because they cannot order the quantities they need.

She added that low reimbursement rates mean manufacturers often prioritise other countries, leaving the UK at the back of the queue. In the meantime, patients affected by shortages are advised to speak to their local pharmacist, who can offer guidance on suitable alternatives where available.

Aspirin Rising Prices Add Pressure On Pharmacies

The shortage has also led to sharp price increases in pharmacies that have managed to secure supplies. The NPA said the cost of a packet of 75mg dispersible aspirin tablets has risen from 18p earlier last year to £3.90 this month.

However, the NHS reimbursement rate remains at £2.18 per packet, meaning pharmacies lose an average of £1.72 every time the medication is dispensed. Mr Picard said this is yet another sign of a pharmacy contract system that urgently needs reform.

Actor Shreyas Talpade recalls that during a shoot for Single Salma in Lucknow, he felt unusually drained after an intense action sequence. In an interview with the Times of India, he revealed, along with the fatigue, there was an odd sensation in his throat, something he had never experienced before. He sat down briefly, brushed it aside, and convinced himself that he was fine.

Yet, something did not sit right with him. Concerned, Shreyas decided to consult a doctor. He underwent an ECG and a 2D echo, and both reports came back normal. While he did not completely ignore what his body was telling him, he also did not probe further. He assumed the medical reports meant there was nothing to worry about.

Months later, in December 2023, Shreyas Talpade suffered a major cardiac episode, an experience that would alter his life in ways he never imagined.

Shreyas Talpade Had No Classic Risk Factors, Yet He Suffered a Heart Attack

Shreyas was only in his mid-40s when the incident occurred, but it changed him both physically and emotionally.

Physically, he now follows lifelong precautions to ensure such an episode does not recur. Regular medication, scheduled follow-ups, routine checkups, and strict adherence to medical advice have become a permanent part of his life.

Emotionally, the impact was even more intense. Shreyas points out that he had none of the four common risk factors associated with heart attacks. He did not smoke or drink. He was neither diabetic nor hypertensive. And yet, the cardiac episode happened.

Shreyas Talpade’s Five Mantras For Heart Health

• Listen to your body: If something feels unusual, do not delay or dismiss it.
• Get tested early: The sooner you detect a problem, the faster you can respond.
• Stay consistent: Fixed timings for meals, medicines, and sleep are essential. A healthy life depends on routine, not randomness.
• Rest adequately: Seven to eight hours of uninterrupted sleep is non-negotiable. It plays a vital role in healing and recovery.
• Monitor your heart regularly: ECGs, 2D echo tests, stress tests, and calcium score screenings can save lives. Prevention is always better than cure.
• Manage stress: Stress is unavoidable, but learning to manage it is crucial. Focus on what you can control and let go of the rest.

Shreyas believes that while life brings uncertainty, many aspects of health remain within our control. After an experience like his, priorities naturally shift. Family becomes the top priority, and staying healthy becomes essential to spend meaningful time with loved ones. That, he says, means sleeping well, exercising four to five times a week, and eating nutritious meals on time.

Heart Attack: Why Timely Meals Matter More Than Extreme Diets

He stresses that while nutritious food is important, eating at regular times is even more critical. Maintaining fixed meal schedules helps the body function better. Having dinner early allows the digestive system enough time to rest. Even the healthiest food, he notes, loses its benefit if meal timings are irregular.

His earlier discipline with clean eating and regular workouts played a significant role in his recovery. Shreyas also believes that post-pandemic health changes and the Covid vaccine may have triggered complications, but his active lifestyle helped him bounce back faster.

According to him, proper nutrition, regular exercise, quality sleep, and balance strengthen the body. Without these habits, the outcome could have been very different. He firmly believes the body responds to the care it receives.

Learning To Handle Stress And Let Go

Shreyas acknowledges that stress is an unavoidable part of life. However, he believes learning how to manage it is essential.

Over time, he has realised that not everything lies within one’s control. Letting go of what cannot be changed is just as important as addressing what can be managed. Wisdom often comes with age, but when someone shares their experiences, he feels it is important to listen.

His message is clear: do not wait for a personal crisis to learn lessons the hard way.

The United States under President Donald Trump’s administration has completed its withdrawal from the World Health Organization (WHO). The US Department of Health and Human Services confirmed the news on Thursday. This has been a longstanding goal of President Trump.

Trump’s Goal To Exit From WHO

During Trump’s first term, he tried to leave WHO, then gave a notice through an executive order on the first day of his second term. It noted that the US would leave the organization. As per law, the US must give WHO a one-year notice and pay all outstanding fees before its departure. This means the US still owes WHO roughly $260 million. However, legal experts said that US is unlikely to pay up and WHO will have little recourse.

Dr. Lawrence Gostin, an expert on global health law and public health at Georgetown University told CNN, “As a matter of law, it is very clear that the United States cannot officially withdraw from WHO unless it pays its outstanding financial obligations. But WHO has no power to force the US to pay what it owes.”

WHO could pass a resolution saying that US cannot withdraw until it pays, however, it won’t risk creating any further tension that there already is.

The HHS on Thursday confirmed that all US government funding to WHO has been terminated and all personnel and contractors assigned or embedded within the organization have been recalled. It also said the US had ceased official participation in WHO-sponsored committees, leadership bodies, governance structures and technical working groups.

What the US Exit From WHO Means for the World

The US government has said it is moving ahead with its decision to exit the World Health Organization (WHO), arguing that the country has not received enough value for the money, staff, and support it has given to the global health body over the years.

Senior officials from HHS said the WHO acted against US interests, especially during the Covid-19 pandemic. They accused the organization of delaying the declaration of a global public health emergency and of praising China’s early response despite signs of underreporting, information suppression, and delays in confirming human-to-human transmission.

HHS also criticized the WHO for being slow to acknowledge airborne spread of Covid-19 and for downplaying the role of people without symptoms in spreading the virus. According to officials, these missteps cost the world precious time as the virus spread rapidly.

While the US has been the WHO’s largest funder, officials pointed out that no American has ever served as the organization’s director-general. “A promise made and a promise kept,” one senior official said, adding that US health policies should not be shaped by “unaccountable foreign bureaucrats.”

That said, the administration has not completely ruled out cooperation with the WHO. When asked whether the US would take part in an upcoming WHO meeting on next year’s flu vaccine composition, officials said discussions are still ongoing.

The government has insisted that leaving the WHO does not mean stepping away from global health leadership. Instead, the US plans to work directly with individual countries, health ministries, non-governmental organizations, and religious groups on disease surveillance and data sharing. This effort is expected to be led by the US Centers for Disease Control and Prevention’s Global Health Center. Officials have promised more announcements on this strategy in the coming months.

However, many public health experts are deeply concerned. Some warn that replacing the WHO with country-by-country agreements will create a fragmented system that lacks coordination and adequate funding. Former CDC officials note that the CDC has staff in about 60 countries, far fewer than the global reach of the WHO.

Critics say the move could leave both the US and the world vulnerable to future outbreaks. Experts argue that infectious diseases do not respect borders and that global cooperation is essential for early detection, data sharing, and rapid response.

Several health leaders have called the decision dangerous and short-sighted, warning that without WHO membership, the US could lose timely access to critical data, virus samples, and genomic information needed to develop vaccines and treatments. WHO’s director-general has described the US withdrawal as a “lose-lose” situation, saying both America and the rest of the world stand to suffer.
