In an era where healthcare is rapidly transforming, diagnostics has emerged as far more than a supporting function it has become the foundation of modern medicine. This central theme unfolded in a recent episode of the InnoHealth Magazine Podcast, where host Dr. Soumya Singh engaged in a deep, nuanced conversation with Dr. Shelly Mahajan, Lab Director & Clinical Head – Genomics at Mahajan Imaging & Labs.

The discussion moved beyond innovation buzzwords to examine the real-world impact of genomics, artificial intelligence, standardization, ethics, and most importantly patient trust.

Diagnostics Moves From the Background to the Frontline

For decades, diagnostics functioned quietly in the background of healthcare. Patients rarely interacted with diagnosticians, and lab reports were often viewed as secondary confirmations of a clinician’s judgment. According to Dr. Mahajan, that perception has fundamentally changed.

“Diagnostics is no longer about confirming illness. It is about predicting disease, preventing it, and managing a person’s entire health journey.”

This shift reflects a broader transformation in healthcare itself. Preventive screenings, wellness monitoring, and early risk assessment now rely heavily on diagnostics. Individuals today engage with testing not only when they are sick, but also when they want to stay healthy making diagnostics a part of everyday life rather than episodic care.

Molecular Diagnostics and the Democratization of Precision

One of the most powerful drivers of this change has been molecular diagnostics. What was once considered niche or highly specialized is now increasingly accessible to routine patients. Dr. Mahajan highlighted how PCR and genomic testing have become household terms, especially following the COVID-19 pandemic.

“Today, we can predict susceptibility to disease by testing DNA from a simple blood or saliva sample and that has completely changed how early we can intervene.”

Molecular diagnostics has revolutionized disease detection across oncology, infectious diseases, and autoimmune disorders. The ability to diagnose earlier, predict risk, and tailor treatment plans has pushed healthcare closer to the ideal of personalized medicine—where therapy is shaped around the individual rather than the average patient.

Artificial Intelligence: Acceleration With Accountability

Artificial intelligence has emerged as a powerful force within diagnostics, improving efficiency, speed, and accuracy in radiology and pathology. AI-powered tools can now screen pathology slides, assist radiologists in detecting early cancers, and reduce diagnostic delays—particularly in regions with limited access to specialists.

However, Dr. Mahajan was unequivocal in her caution: AI is a tool, not a decision-maker.

“AI can screen faster and reduce errors, but it cannot replace clinical judgment. Without human oversight, even the smartest algorithm can misdiagnose.”

She emphasized that AI systems are only as good as the data on which they are trained. A lack of diversity or quality in training datasets can introduce bias, leading to skewed results that directly impact patient care. Continuous validation, transparency, and regulatory oversight are therefore critical to safe AI adoption.

Standardization: The Backbone of Credibility

One of the most pressing concerns raised in the conversation was the lack of uniformity across diagnostic laboratories. Variations in reference ranges, methodologies, and reporting standards often leave patients confused and clinicians uncertain.

Dr. Mahajan stressed that accreditation, adherence to international quality standards, regular audits, calibrated equipment, and continuous staff training are not optional—they are fundamental. Without standardization, diagnostics risks becoming volume-driven rather than value-driven, leading to over-testing, patient anxiety, and unnecessary healthcare costs.

Over-Testing and the Need for Value-Based Diagnostics

While access to diagnostics has improved, it has also created a paradox: more testing does not always mean better care. Over-testing can result in false positives, misdiagnosis, and emotional distress for patients.

Dr. Mahajan advocated for stronger collaboration between clinicians and diagnosticians, evidence-based testing protocols, and better patient education. The goal, she explained, is smarter diagnostics, not more diagnostics.

“We need to move away from volume-based diagnosis and focus on tests that actually add value to a patient’s treatment journey.”

Transparency, Ethics, and Rebuilding Patient Trust

Addressing recent controversies around lab practices and data integrity, Dr. Mahajan underscored that trust is fragile—and once lost, difficult to rebuild. Transparency, she argued, is the most powerful tool laboratories have.

She noted a positive cultural shift: patients now actively want to speak with diagnosticians, discuss reports, and understand their health data. This growing engagement reflects a new era where patients expect not just accuracy, but accountability and empathy.

The Road Ahead: Technology With a Human Core

Looking forward, Dr. Mahajan expressed optimism about emerging breakthroughs such as multi-omics diagnostics, AI-assisted tools for rural healthcare, and continuous monitoring through wearables. These innovations promise earlier detection, ultra-personalized treatment, and improved access.

Yet the podcast made one truth abundantly clear: technology alone cannot define the future of diagnostics.

The future will belong to systems that combine scientific excellence, ethical practice, rigorous quality standards, and human judgment—where every report carries not just data, but responsibility.

As this episode of the InnoHealth Magazine Podcast demonstrates, diagnostics is no longer just about tests. It is about trust, transparency, and putting patients at the heart of innovation.

Hantavirus remains one of the most overlooked zoonotic threats today, rare enough to escape sustained public attention yet severe enough to cause alarm when outbreaks occur. With high case fatality rates and persistent animal reservoirs, it continues to expose gaps in global infectious disease preparedness.

What Hantavirus Is, and How It Spreads

Hantaviruses are single-stranded RNA viruses carried primarily by rodents, with each strain usually linked to a specific host species. Humans are typically infected through environmental exposure, not bites.

Transmission can occur through:

• inhalation of aerosolised particles from rodent urine, saliva, or faeces
• contact with contaminated surfaces
• rarely, person-to-person spread

Hantaviruses cause two major syndromes:

• Hantavirus Pulmonary Syndrome (HPS), seen mainly in the Americas
• Hemorrhagic Fever with Renal Syndrome (HFRS), more common in Europe and Asia

More than 20 hantavirus strains are known to infect humans. The current outbreak strain, the Andes virus, is particularly concerning because it is the only known hantavirus capable of human-to-human transmission.

Why Hantavirus Is Difficult to Detect, and Dangerous to Miss

The biggest challenge with hantavirus is timing. Early symptoms often resemble routine viral illnesses, while severe respiratory complications may appear only 4 to 10 days later, rapidly progressing to respiratory failure and shock.

The current outbreak reflected this clearly. The first reported patient developed symptoms on April 6 and died within five days. Hantavirus was only suspected after additional cases emerged, by which time passengers had already travelled across multiple ports.

Three major gaps continue to complicate hantavirus management:

1. Delayed Detection

• No routine hantavirus screening exists in most port health or travel medicine systems
• Awareness remains limited outside endemic regions
• Early cases are often mistaken for influenza or other respiratory infections

2. Limited Treatment Options

• There are currently no globally licensed vaccines or antivirals for hantavirus
• Treatment is largely supportive and dependent on rapid ICU access
• Investigational therapies such as ribavirin, favipiravir, and lactoferrin remain under study

3. Fragmented Surveillance

• Rodent population monitoring is rarely integrated into public health warning systems
• Most outbreak responses remain reactive rather than predictive

Hantavirus outbreaks are not defined only by viral severity but also by how easily the disease can remain invisible during its earliest stages.

The Innovation Imperative

The technology needed to improve hantavirus detection already exists. The challenge is deployment.

Recent real-time RT-qPCR assays can detect hantavirus with sensitivity above 92% and specificity reaching 100%. A dual RT-qPCR system developed in 2025 can even differentiate hantavirus from other febrile illnesses with similar presentations, exactly the kind of tool that could have identified the MV Hondius cases earlier.

What is still missing:

• portable point-of-care diagnostics
• integration into port health and travel medicine systems
• rapid deployment in field settings

Genomic surveillance has advanced rapidly as well. Next-generation sequencing can now:

• track viral evolution
• identify emerging strains
• map transmission chains in real time

Yet most countries still lack a coordinated One Health surveillance framework linking human, animal, and environmental health data.

The vaccine gap is equally striking.

Since 2023, Korea University Vaccine Innovation Centre and Moderna have been developing an mRNA-based hantavirus vaccine. Experimental studies have shown protection in animal models, but as of April 2026, human clinical trials remain delayed due to funding limitations.

The contrast is difficult to ignore:

• the mRNA platform transformed pandemic vaccine development within years
• yet promising hantavirus candidates remain stalled despite high fatality rates in severe infections

In response to the current outbreak, the World Health Organisation deployed field experts and distributed diagnostic kits across multiple countries.

Outbreak response alone is not enough; health systems must be able to detect and contain threats before they spread across borders.

The Larger Lesson

Hantavirus is more than an isolated outbreak. It reflects the growing challenge of zoonotic diseases emerging alongside environmental disruption, global mobility, and expanding human-wildlife contact. Pop

The reservoir will persist, whether in Patagonia, Central Asia, or Southeast Asia. The real question is whether future outbreaks are detected early enough to stop transmission before they spread across borders.

That challenge is no longer scientific alone. It is a question of preparedness, investment, and public health prioritisation.
