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.

The COVID-19 pandemic may have ended, but memories of overwhelmed hospitals, medicine shortages, overworked healthcare workers and deaths remain fresh for many who lost loved ones.

US-registered nurse and whistleblower Kimberly Overton has claimed that some COVID-19 patients died because of hospital treatment protocols, including the use of remdesivir and ventilators.

“Patients did not die of COVID. They were killed by hospital protocols — remdesivir, ventilators, and the denial of life-saving treatments,” Overton claimed on several podcasts.

Nurses Claims Patients Died From Hospital Protocols

Overton has also described what she says she witnessed while working in an ICU during the pandemic.

“Ventilators are the new gas chambers." "I worked ICU during the pandemic... I could not watch one more of my patients needlessly die due to deadly hospital protocols."

“No bodies piling up at homes or on streets — they were dying inside hospitals from medical mismanagement and a corrupt system. This wasn't a virus. It was protocol murder”.

Overton founded the Nurse Freedom Network, a US-based organization that advocates for nurses, patients and informed consent and has amplified criticism of COVID-era hospital protocols.

Overton is not the first nurse to make such claims.

In 2023, Gail McCrae, who worked at a hospital in California's Bay Area, also criticized COVID-era hospital protocols and the use of remdesivir.

McCrae said remdesivir was the main medication nurses at her hospital were allowed to administer to hospitalized COVID-19 patients. She also questioned the timing of treatment, claiming patients were receiving the drug 10 to 12 days after symptoms began.

During one double shift, McCrae said she noticed an increase in “code blue” calls, referring to emergencies requiring resuscitation or immediate medical intervention.

“And nine out of 10 times those code blues were to the lower level, down to the clinic, where they were injecting people. [Two of] my colleagues did in fact go into anaphylaxis, after receiving their shots.”

What Was The Remdesivir Controversy?

Remdesivir became one of the first widely used antiviral treatments for hospitalized COVID-19 patients in the US.

The NIH-backed ACTT-1 trial found that remdesivir shortened recovery time, with patients recovering in a median of 10 days compared with 15 days in the placebo group. However, the WHO-led Solidarity trial found little or no effect on mortality, need for ventilation or hospital stay.

In November 2020, WHO issued a conditional recommendation against using remdesivir in hospitalized COVID-19 patients, citing insufficient evidence that it improved survival or other important outcomes.

The US FDA, meanwhile, granted full approval to remdesivir in October 2020 for certain hospitalized COVID-19 patients.

Trump Also Received Remdesivir

Then-US President Donald Trump was hospitalized at Walter Reed National Military Medical Center after testing positive for COVID-19 in October 2020. His treatment included remdesivir.

Dr Anthony Fauci, who led the US response to the pandemic, had earlier described remdesivir as a potential “standard of care” after early trial results showed that it reduced recovery time.

COVID Origins and Deaths

According to the WHO, more than 7.1 million COVID-19 deaths have been officially reported worldwide since the pandemic began.

However, WHO cautions that the reported figure does not necessarily reflect the actual number of deaths because countries differ in testing, definitions and reporting practices, and many have reduced or stopped reporting COVID-19 deaths.

According to the US Centers for Disease Control and Prevention (CDC), more than 1.2 million COVID-19 deaths have been recorded in the United States since the pandemic began.

WHO's latest data also show that COVID-19 deaths continue to be reported globally, although surveillance and reporting have declined significantly.

The origins of SARS-CoV-2 also remain under investigation. The major hypotheses include zoonotic spillover and a possible laboratory-related incident, with scientific assessments continuing to evolve.

Seven in 10 general practitioners in the United Kingdom believe adult attention-deficit/hyperactivity disorder (ADHD) is being overdiagnosed, according to a survey of 829 doctors.

The observation has reignited debate over the dramatic increase in adult ADHD referrals and diagnoses.

The survey, conducted by GP publication Pulse, found that 410 GPs described adult ADHD as “very overdiagnosed” while 173 considered it “slightly overdiagnosed”.

Only 50 said it was diagnosed about right, while 148 believed it was underdiagnosed to some degree.

Pulse said that the survey should be viewed as a GP's opinion rather than a proven scientific estimate of overdiagnosis.

The survey also found that GPs estimated an average of 81.3% of patients they referred to adult ADHD services eventually received a positive diagnosis.

But that figure does not mean that 81% of people with suspected ADHD have it. These patients had already been referred for an assessment by a specialist, meaning they had passed through an initial clinical screening process.

Doctors Are Concerned About ADHD Overdiagnosis In Adults

Some GPs responding to the survey raised concerns that assessments may sometimes be too narrow and focus on identifying ADHD without considering other conditions that can cause similar symptoms that could overlap with ADHD. These can include anxiety, depression, trauma and other mental health conditions.

One GP told Pulse that they were concerned about “superficial” assessments and whether patients’ histories of trauma or adverse childhood experiences were being considered accurately.

There are also concerns around the growing use of private assessment providers. Some GPs surveyed said they believed positive diagnosis rates were higher among private providers than NHS services, although these are individual doctors’ observations rather than evidence represented nationally.

At the same time, Dr Katie Bramall, chair of the BMA's GP committee, argued that a high positive diagnosis rate among referred patients is not necessarily evidence of overdiagnosis.

She said lengthy NHS waits may mean that only people who remain convinced that ADHD is affecting them significantly eventually reach assessment.

She also pointed to changing understanding of ADHD, including how it can present in women and adults, as one reason more people are being recognised.

Is ADHD Being Overdiagnosed?

An interim report from the UK government's independent review of ADHD, autism and mental health conditions said recorded ADHD diagnoses in England have increased, particularly among younger adults and women.

The NHS's independent ADHD Taskforce has previously estimated adult ADHD prevalence at around 2-3%, while recorded diagnoses were significantly lower in earlier datasets. The taskforce concluded that under-recognition remained a problem.

The Royal College of Psychiatrists has also agreed that the rise in diagnoses should not be automatically interpreted as overdiagnoses of ADHD.

It has pointed to other factors like better awareness and improved recognition, while also addressing concerns about online self-assessment that may not be always accurate.

The government review therefore says that the current situation is more complex than simply labelling ADHD as either overdiagnosed or underdiagnosed. It highlights the lack of recent, large-scale representative data measuring adult ADHD prevalence in England.

On the other hand, demand for ADHD treatment continues to climb. NHS figures cited by Pulse show prescriptions for ADHD medicines increased by 29% between July 2025 and June 2026 compared with the previous 12 months, with an average of 238,000 patients receiving these medicines each month.

Signs of ADHD

For people asking themselves if they might have ADHD, one must look to medical sources over social media popularity. The NHS says that signs of ADHD in adults are most often:

• Difficulty with organization and time management
• Having trouble with following instructions
• Having trouble keeping one's focus on tasks and seeing them through
• Feeling restless or being impatient
• Risk-taking and being impulsive
• Trouble in relationships or in social situations

Medicine safety must become everyone’s responsibility, the Indian government said today while launching the Biovigilance Program to monitor adverse events linked to organ and tissue transplantation.

Under the program, the Indian Pharmacopoeia Commission (IPC) will lead efforts to strengthen the reporting, assessment, monitoring and prevention of adverse events associated with medicines and biological products used in organ and tissue transplantation, including products administered to donors and recipients.

Together, pharmacovigilance, materiovigilance and biovigilance initiatives will strengthen safety monitoring across medicines, medical devices and transplant procedures.

The program was launched by Union Minister of State for Health & Family Welfare and Chemicals & Fertilizers Anupriya Patel at the 6th National Pharmacovigilance Week organized by the IPC at Dr. Ambedkar International Centre in New Delhi.

New Medicine Safety Initiatives

Patel also launched initiatives to help healthcare professionals make informed, evidence-based decisions when prescribing and using medicines. These include:

• The 7th Edition of the National Formulary of India (NFI),
• The Guidance Document for Hospitals in India for Safety Monitoring and Reporting of Medical Device-Related Adverse Events,
• The ADR-PvPI 2.0 Mobile App for iOS users.

“Rational use of medicines and continuous safety monitoring are integral to public health,” said Patel. She added that “every patient must receive the right medicine, of assured quality, in the right manner and with the highest possible degree of safety”.

“The NFI serves as an important bridge between scientific standards and clinical practice, guiding healthcare professionals in the appropriate and rational use of medicines,” Patel said.

India’s Pharmacovigilance Network

Patel emphasized that medicine safety is a continuous responsibility—from the development and manufacture of a drug or medical device to its prescription, dispensing, use and post-market monitoring.

She also highlighted the country’s progress in pharmacovigilance, noting that “India has built a strong indigenous ecosystem capable of generating, collecting, processing and analyzing medicine-safety data from across the country”.

India has moved from the 123rd position during 2009–2014 to 8th globally in contributions to the WHO patient safety database, Patel said.

The Pharmacovigilance Program of India (PvPI), coordinated by the National Coordination Centre at IPC, systematically collects, assesses and analyzes adverse drug reaction information. The Materiovigilance Program of India (MvPI) monitors adverse events associated with medical devices.

AI And Patient Reporting

Patel said digital initiatives, including NFI Online, IP Online, ADR-PvPI 2.0 Mobile App and the Adverse Drug Reaction Monitoring System (ADRMS), are making medicine-related information and adverse-event reporting more accessible, transparent and responsive.

She called for greater use of emerging technologies, including artificial intelligence and advanced data analytics, to strengthen medicine-safety systems and enable timely generation and use of safety evidence.

The Minister also stressed the need to increase patient participation in adverse-event reporting. She noted that digital platforms, mobile applications and helplines have made reporting easier, and called for addressing the “missing link” of patient reporting.

"Around 1,150 ADR reporting centers are currently operational across public and private hospitals and medical colleges in the country, along with medical-device vigilance facilities. The government plans to expand these capabilities to the primary healthcare level," Patel said.

India’s Patient Safety Push

Referring to the vision of Viksit Bharat 2047, Patel said patient safety must remain a key national priority. She called for India to build on its position as the “pharmacy of the world” and aspire to become a global leader in pharmacovigilance sciences and patient safety.

“Medicine safety must become everyone’s responsibility. Every single reported event can save a life.”

She said collective participation would be critical to building a strong culture of medicine safety and promoting the rational use of medicines.
