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 remarkable emergency response, Dubai paramedics revived a man who collapsed from a heart attack, earning widespread praise on social media.

The man reportedly collapsed suddenly and showed no signs of consciousness or a pulse. People at the scene immediately alerted emergency services, who responded within minutes. The team began cardiopulmonary resuscitation (CPR) using an advanced CPR machine.

A video now going viral on social media shows paramedics arriving within minutes and performing CPR using the LUCAS 3 automatic chest compression device. The machine, which delivers high-quality chest compressions more consistently than manual CPR, helped circulate blood to vital organs and revived the man within minutes.

“Dubai’s emergency response looks like the future: a man collapses from a heart attack, paramedics arrive within minutes, strap on the LUCAS 3 automatic CPR device, and revive him right there,” a social media user wrote.

“If there were a machine like this, it would be a huge help because people wouldn’t have to perform CPR for a long time,” another user added.

How The LUCAS 3 Device Saves Lives

The LUCAS 3 chest compression system is a mechanical CPR device originally developed by Swedish startup Jolife AB in collaboration with Norwegian inventor Willy Vistung and cardiologist Stig Steen. The device and company were later acquired by medical technology company Stryker in 2016.

The device is designed to deliver continuous, high-quality chest compressions while reducing physical strain on caregivers.

According to the company, studies have shown that the LUCAS device can improve blood flow to the brain and achieve higher EtCO2 values compared to manual chest compressions. With more than 50,000 devices in use worldwide, including within the Dubai Corporation for Ambulance Services, a patient is reportedly treated using the device approximately every minute, it added.

What Is CPR? How To Give CPR?

CPR, or Cardiopulmonary Resuscitation, is an emergency life-saving technique used when a person stops breathing or their heart stops beating. Quick action is critical, as CPR can double or even triple a person’s chances of survival.

Steps to keep in Mind While Giving CPR

Step 1: Check The Surroundings

Ensure the area is safe by checking for dangers such as traffic, fire, or falling objects.

Step 2: Position The Person

Lay the person on their back on a firm surface and open the airway by tilting the head back slightly. Check the mouth for any visible obstruction and remove it carefully if possible.

Step 3: Check Breathing

Listen for breathing sounds for no more than 10 seconds. If the person is not breathing normally, begin CPR immediately.

Step 4: Chest Compressions

Place the heel of one hand at the center of the chest, slightly below the nipple line. Place your other hand on top and interlock your fingers. Keep your elbows straight and push hard and fast — about 2 inches deep — at a rate of 100 to 120 compressions per minute. Allow the chest to rise fully between compressions.

Step 5: Rescue Breaths

After 30 compressions, tilt the person’s head back, lift the chin, pinch the nose shut, and seal your mouth over theirs. Give two rescue breaths, each lasting about one second, while watching for chest rise. If the chest does not rise, reposition the head and try again.

Step 6: Repeat The Cycle

Continue alternating 30 chest compressions with 2 rescue breaths until the person starts breathing or emergency medical professionals arrive.

Key Considerations For CPR

• CPR should be used in emergencies such as cardiac arrest, drowning, choking, or severe trauma.

• Always confirm that the person is unresponsive and not breathing normally before starting CPR.

• CPR is intended for emergency situations. If a healthcare professional is nearby, seek their assistance immediately.

Excessive screen time use is harming sleep, mental health, learning, and development of children, according to a new advisory by the US surgeon general’s office, which urged parents to limit children’s screen time.

Even as President Donald Trump's nominee for surgeon general awaits confirmation, the "Harms of Screen Use" bulletin warns that children and teens are spending more time on their digital devices than on sleep or school, the USA Today reported.

It noted that excessive screen use is linked to heavy or compulsive screen use

• anxiety,
• depression,
• poor academic performance,
• behavioral problems
• developmental delays.

Health and Human Services Secretary Robert F. Kennedy Jr. said evidence of risks to children’s physical and mental health is “mounting,” even though screens can also provide some benefits.

The advisory promotes the slogan “Live real life,” encouraging children and families to replace excessive screen use with in-person activities and healthier routines.

Alongside the report, the officials also released a toolkit recommending steps for parents, schools, healthcare providers, and policymakers to help reduce screen dependence and encourage safer technology habits among young people.

The advisory also links excessive and "compulsive" screen use to

• poor sleep and school performance,
• mental health issues like anxiety and depression,
• behavioral and social issues, substance abuse, and developmental disruptions.

The report aligns with recent studies, which show how too much screen time affects developing minds.

Recent findings from the All India Institute of Medical Sciences, Delhi, suggest that early digital exposure to children before the age of one increases the baby's risk of autism.

The findings led by the Department of Pediatric Neurology showed that infants exposed to high levels of digital media at around one year of age are significantly more likely to display autistic signs by the time they reach age three.

India has also issued pediatric and education guidelines advising parents to limit screen exposure for young children, though there is no nationwide ban. States like Karnataka and Andhra Pradesh have also taken up action against social media use and screen time.

Countries banning screen time

While countries are not fully “banning” screen time, several of them have introduced restrictions, guidelines, or proposed laws aimed at reducing children’s screen time, especially around smartphones and social media in schools.

• France banned smartphones in primary and middle schools in 2018 and has tested stricter “digital pause” policies for students under 15.
• China has some of the world’s toughest rules, including limits on video game play for minors, restrictions on nighttime gaming, and proposed limits on smartphone use for children.
• South Korea introduced laws targeting gaming addiction among minors, including past shutdown rules that blocked late-night gaming for children.
• Netherlands and Finland have encouraged schools to restrict phones in classrooms to improve concentration and learning.
• Australia has debated stronger social media age restrictions, and several states have tightened school phone bans.
• United Kingdom schools widely enforce smartphone bans, while lawmakers continue discussing stricter online safety rules for children.
• Sweden has pushed for reduced screen exposure in early childhood education, emphasizing printed books and traditional learning methods.

India has successfully linked the health records of more than 100 crore people with Ayushman Bharat Health Accounts (ABHA) under the Ayushman Bharat Digital Mission (ABDM), the Ministry of Health and Family Welfare said today.

Implemented by the National Health Authority, the milestone marks a major step towards building an integrated, citizen-centric, and interoperable digital healthcare ecosystem in the country.

“The linking of over 100 crore health records with ABHA is an important milestone in the journey of Ayushman Bharat Digital Mission. ABHA-linked health records empower citizens with secure and consent-based access to their health information and support continuity of care across the healthcare ecosystem,” said Dr. Sunil Kumar Barnwal, CEO, NHA.

The Growing Adoption Of ABDM

According to the Ministry, more than 450 public and private health technology solutions have integrated with the ABDM ecosystem, enabling digitisation and seamless exchange of health records across healthcare facilities.

The ministry said ABDM doubled the number of linked health records from 50 crore in February 2025 to over 100 crore in just 15 months.

Nearly 10 crore health records are now being linked every two to three months. From fewer than 1,000 linked records during its initial phase to over 100 crore today, ABDM has evolved into one of the world’s largest digital health ecosystems.

Uttar Pradesh emerged as the leading contributor with over 15.03 crore ABHA-linked health records, followed by Andhra Pradesh with over 11.95 crore linked records.

Bihar, Rajasthan, and Gujarat also recorded major progress by linking over 7.37 crore, 6.32 crore, and 4.77 crore health records, respectively.

• eSushrut by Centre for Development of Advanced Computing
• Gujarat government’s TeCHO platform
• Rajasthan government’s iHMS platform

Private health technology partners and ABDM-enabled digital solutions have also contributed significantly towards the creation and linkage of ABHA-linked health records.

What Is ABHA?

ABHA is a unique digital health identity that allows citizens to securely link and access their health records across hospitals, clinics, laboratories, and healthcare providers.

Through ABDM’s consent-based health information exchange mechanism, citizens can digitally share their medical records with registered healthcare providers while maintaining the privacy and security of personal health information.

“ABDM is designed to place citizens at the center of the digital health ecosystem. With consent-based sharing of health records, individuals can access their medical information whenever required and share relevant records with healthcare providers digitally. This will help make healthcare delivery more accessible, efficient, and patient-centric,” Barnwal said.

Key Digital Building Blocks Of ABDM

The Ayushman Bharat Digital Mission is creating the digital public infrastructure required for an interoperable healthcare ecosystem through key digital building blocks such as:

• Ayushman Bharat Health Account (ABHA)
• Healthcare Professionals Registry (HPR)
• Health Facility Registry (HFR)
• Health Information Exchange and Consent Manager (HIE-CM)
• Unified Health Interface (UHI)
• National Health Claims Exchange (NHCX)

With over 100 crore health records now linked with ABHA, ABDM has marked another milestone towards creating longitudinal digital health records for citizens and enabling a more connected, paperless, efficient, and patient-centric healthcare ecosystem in the country.
