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.

In a landmark judgement, the Supreme Court today allowed passive euthanasia for a 32-year-old man, living in a vegetative state for the last 13 years.

A bench comprising Justice JB Pardiwala and Justice KV Viswanathan allowed the withdrawal of life support for Harish Rana, a resident of Ghaziabad, who has been in a coma and kept alive on tubes for breathing and nutrition after sustaining severe head injuries following a fall from a building in 2013 in Chandigarh.

It is the first known case of a court-ordered passive euthanasia in India, since it was legalised in 2018 and modified in 2023, recognizing the fundamental right to die with dignity.

"Harish Rana, presently aged 32 years, was once a young, bright boy. He met with a tragic life-altering accident after a fall from the fourth floor of his paying guest accommodation. His brain injury left him in a condition of Persistent Vegetative State (PSV) with 100 percent quadraplegia... Medical reports show that his medical condition has not improved in the past 13 years," LiveLaw quoted the bench as saying.

The Court noted that the continuation of his treatment -- Clinically Administered Nutrition (CAN) via surgically installed PEG tubes -- can just prolong his biological existence but will not lead to any therapeutic improvement.

What Is The Case Of Harish Rana?

Harish was a BTech student in Chandigarh who suffered severe traumatic brain injury after falling from the fourth floor of his paying guest accommodation in August 2013.

Since then, he has remained bedridden and dependent on others for all activities of daily life.

Harish's father, the petitioner, first approached the Delhi High Court in 2024, seeking permission for passive euthanasia, but was rejected as the patient was not terminally ill.

The same year, the petitioner knocked on the doors of the Supreme Court, which, though it refused to entertain the plea, directed the Uttar Pradesh government to bear the treatment expenses.

In 2025, the petitioner filed a miscellaneous application in the Supreme Court, noting that Harish's condition had no scope for improvement.

The Court then directed the constitution of a Primary Medical Board led by the District Hospital in Noida to examine his health, as well as a Secondary Medical Board constituted by the All India Institute of Medical Sciences (AIIMS).

After perusing the report, Justice Pardiwala remarked that it's a "sad report" and the man can't continue to live like this. Before passing the final order, the Court met the parents, LiveLaw reported.

The Court has asked AIIMS to provide palliative care, so that the withdrawal of CAN can be given effect to.

To maintain the dignity of death, the apex Court said that the life support must be withdrawn with a tailored plan.

1st Passive Euthanasia: What's New From The 2018 Judgment

In 2018, a five-judge Constitution Bench had recognized and given sanction for passive euthanasia, and living will/advance directives.

Later in 2023, the SC modified the guidelines, noting that withdrawal of life support is permissible only after the approval of the Primary and Secondary Medical Boards.

With the Harish Rana judgment, the apex Court today clarified how passive euthanasia should be applied in cases where a patient’s life is being supported by feeding tubes.

The top Court waived off the reconsideration period of 30 days and noted that the medical treatment, including the CAN administered to the patient, can be withdrawn or withheld.

What is Passive Euthanasia

Passive Euthanasia allows a terminally ill or irreversibly comatose patient to die naturally. It involves deliberately withholding or withdrawing life-sustaining treatments (like ventilators, feeding tubes, or medication). It has been legal since 2018, but under strict guidelines.

In Active Euthanasia, patients are administered a lethal injection to cause death. It is illegal in India and considered an offence.

The Aruna Shanbaug case in 2011 opened the door for passive euthanasia in India for the first time.

The top Court rejected euthanasia in the case of Shanbaug, a nurse at Mumbai's KEM hospital who was in a vegetative state for 42 years after an assault in 1973, as the hospital staff who cared for her for decades did not support stopping treatment.

Shanbaug continued to be under care and passed away naturally in 2015

However, in her case, the court made the judgment allowing for passive euthanasia in certain rare situations under strict conditions.

In the wake of a shocking incident in Uttar Pradesh’s Kanpur, where two engineers allegedly died within 48 hours of undergoing hair transplant surgery by a dentist, the Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) and the Association of Plastic Surgeons of India (APSI) have pressed the need for stricter rules for aesthetic and hair restoration procedures.

The doctors raised concerns about patient safety and called for ramping up training standards, even as many such cases where unqualified medical practitioners performed aesthetic procedures leading to severe infections, loss of sight, and many complications have been documented from across the country.

Traditionally, these procedures were performed by specialists such as dermatologists and plastic surgeons trained under the regulatory framework of the National Medical Commission (NMC).

However, experts said the issue has become more complicated after the Dental Council of India (DCI) allowed MDS dental surgeons, under provisions of the Dentists Act, 1948, to perform certain aesthetic procedures and hair transplantation.

“Aesthetic procedures and dermatology demand additional training. In addition to the MBBS degree, a dermatologist training program requires three years of residency at a postgraduate level in dermatology at certain accredited medical schools,” Dr Vinay Singh, President IADVL said.

He added that the training also includes a condensed curriculum of various skin ailments, hair problems, and advanced procedures in dermatology.

“Allowing professionals without comprehensive medical training in skin diseases, hair disorders, and surgical complication management to perform such procedures could dilute training standards and increase risks for patients,” warned Dr. Rajat Gupta, Senior Consultant Plastic Surgeon, Delhi.

The experts also pointed out that hair transplant is a modern medical procedure and should only be conducted by Registered Medical Practitioners (RMPs) who are specialized in that area.

Dr. Aditya Aggarwal, Senior Consultant Plastic Surgery, Medicity Medanta Hospital, shared that the surgery requires knowledge regarding the biology of the skin, the disorders of the hair, how to manage infections, and how to manage complications.

The associations urged the government to issue comprehensive guidelines and ensure strict implementation of existing regulations to curb quackery and safeguard public health.

Further, they advised the patients to verify the doctor’s qualifications and registration with the state medical council before undergoing any skin, hair, or cosmetic treatment.

The public must remain alert and avoid falling prey to misleading advertisements or treatments offered by unlicensed practitioners, the experts said.

About 6 million people in India's capital city are living with several vision problems, such as poor distance vision or near vision, according to a recent study by doctors at All India Institute of Medical Sciences (AIIMS), New Delhi.

The study, Dr. Rajendra Prasad Centre for Ophthalmic Sciences at AIIMS, and submitted to the World Health Organization (WHO), also flagged major gaps in eye care services in Delhi, the Times of India reported.

An estimated one-third of the population in the national capital was identified with refractive errors or presbyopia -- conditions that can usually be corrected with a pair of glasses. Globally, 826 million people suffer from presbyopia.

About 70 percent of older adults in the capital city were identified with the problem.

Alarmingly, about 13.1 percent school-going children had refractive errors, Dr. Praveen Vashist, professor and head of community ophthalmology at AIIMS, was quoted as saying.

Gaps In Eye Care

The study showed a lack of access to vision correction. While just 60 percent of people needing distance vision correction could access care, those with near vision correction could access care in over 47 percent of cases.

Further, the doctors found:

• women had the lowest access to spectacles compared to men
• lack of trained eye care workers,
• the affordability of spectacles,
• limited outreach to vulnerable groups -- elderly patients, rural women, and economically weaker populations.

But Dr. Vashisth noted that Delhi currently has only 1,085 ophthalmologists and approximately 489 optometrists.

Further, only 50 community-level vision centers, out of the has 249 eye care institutions in the city were found to be functioning. Moreover, only about 25 percent of children were receiving free spectacles through public health initiatives.

Global Eye Burden

According to the World Health Organization (WHO), at least 2.2 billion people worldwide have near or distance vision impairment. Of these, at least 1 billion cases could be prevented with increased access to eyeglasses and cataract surgeries

The WHO identifies refractive errors and cataracts as the leading causes of vision impairment and blindness.

Vision loss can affect people of all ages; however, most people with vision impairment and blindness are over the age of 50.

Here's how to maintain a healthy vision:

• Eat fruits and veggies, especially leafy greens like spinach, kale, and fish like salmon and tuna, to protect your sight.
• Be physically active, as being overweight or obese can increase risk for diabetes and other conditions that can lead to vision problems.
• If your vision gets blurry, use glasses to help you see better.
• Always wash your hands before putting them close to your eyes, especially if you’re putting in or taking out contact lenses.
• Use protective eyewear while playing a favorite sport or mowing the lawn
• Wear your shades to prevent the sun’s rays from hurting your eyes.
• Give your eyes a break with the 20-20-20 rule: Every 20 minutes, look about 20 feet away for 20 seconds.
• Quit smoking as it can put you at risk of serious eye issues, leading to blindness.
