Disease X, as introduced by the World Health Organization (WHO) in 2018, is not an actual new disease but rather a conceptual term used to describe a hypothetical pathogen that has not yet been identified but possesses the potential to cause a global pandemic.
Global health experts are raising concerns, suggesting that COVID-19 could be a precursor to a potentially more catastrophic Disease X Pandemic, as reported by the Daily Mail. Dame Kate Bingham, the leader of the UK’s Vaccine Taskforce, acknowledged the relatively lower severity of COVID-19 and expressed gratitude for that fact. However, she also issued a stark warning, cautioning that the next pandemic could result in the loss of at least 50 million lives. This underscores the ongoing need for global preparedness and vigilance in the face of emerging infectious diseases.

This approach helps bridge institutional gaps, identify priority risk pathogens, and formulate effective mitigation strategies for emerging and re-emerging diseases, including potential Disease X.
Preventing global catastrophes like Disease X requires a proactive and united effort on a global scale. By implementing these preventive measures and fostering international cooperation, the world can better prepare for and respond to potential health threats, ultimately safeguarding public health and global stability.
Dame Kate Bingham, the former chair of the UK’s Vaccine Taskforce, has delivered a sobering warning regarding the potential gravity of Disease X. She emphasized that the world has been fortunate in the sense that COVID-19, while impactful, did not manifest as a more deadly threat. Dame Kate underscored the very real possibility that the next pandemic could be considerably more lethal, emphasizing the need for continued vigilance and preparedness on a global scale.
To prevent the onset of the next pandemic, it is imperative that we undertake the following measures:
Invest in Surveillance: Establish robust global surveillance systems designed to detect emerging threats at their earliest stages.
Promote One Health: Acknowledge the interconnectedness of human, animal, and environmental health as a means to identify and mitigate risks comprehensively.
Antibiotic Use: Implement antimicrobial stewardship programs to counter the rise of drug-resistant pathogens.
Strengthen Healthcare Systems: Enhance the capacity of healthcare systems, not only for pandemic response but also to cater to routine healthcare requirements effectively.
Global Cooperation: Foster international collaboration, emphasizing information sharing, equitable resource allocation, and collective research endeavors.
Preparedness Plans: Develop comprehensive pandemic preparedness plans, encompassing the stockpiling of essential supplies and the establishment of rapid response teams.
These proactive measures are essential to minimize the potential impact of future pandemics and bolster global readiness in the face of emerging infectious diseases.
The warnings issued by scientists resonate with the World Health Organization’s (WHO) earlier prediction of an “inevitable” “Disease X” pandemic, a term introduced in 2018 prior to the emergence of COVID-19. Within the WHO’s “Blueprint list of priority diseases,” potential threats such as Ebola, SARS, and Zika are highlighted. Disease X serves as a symbol of the expectation that a severe global epidemic could originate from a pathogen that has not yet been identified as affecting humans. Often, these pathogens have zoonotic origins, similar to Ebola, HIV/AIDS, and COVID-19.
This underscores the critical importance of preparedness and ongoing research to mitigate the potential impact of future pandemics. It also emphasizes the inherent unpredictability of infectious diseases and the need for vigilance and proactive measures on a global scale.
World Health Organization (WHO) has recognized the significance of Disease X as a theoretical yet substantial concern. “Disease X” represents the unforeseen outbreak that scientists and public health experts are apprehensive about, as it has the potential to trigger a worldwide health emergency when it inevitably arises. The WHO emphasizes the importance of preparedness, vigilant surveillance, and global collaboration to effectively mitigate the repercussions of such an unpredictable threat.
In recent years, the world has been witness to a series of infectious disease outbreaks, ranging from Monkeypox to Crimean-Congo haemorrhagic fever, with the ongoing threat of COVID-19. What drives the growing concern for yet another pandemic looming on the horizon? Several factors contribute to this apprehension:
1. Climate Change: Climate change stands as a key factor fueling the potential emergence of Disease X. As global temperatures continue to rise, ecosystems undergo disruption, compelling wild animals to seek new habitats in more densely populated areas. This phenomenon heightens the risk of viruses making the leap from animals to humans, a process known as zoonotic spillover. Experts believe that climate change is altering the dynamics of infectious disease transmission, increasing the likelihood of future pandemics.
2. Forcible Animal Relocation: The disruption of natural habitats, a consequence of climate change, necessitates the forced relocation of various animal species. This movement brings wildlife into closer proximity to human populations, creating opportunities for novel pathogens to spill over from animals to humans.
3. Human Impact: The expansion of urban areas, deforestation, and encroachment into previously untouched natural habitats amplify the likelihood of humans encountering new and potentially hazardous pathogens. These anthropogenic activities increase the risk of disease transmission between wildlife and human populations.
These factors collectively contribute to the growing concern about the potential emergence of Disease X, highlighting the complex interplay between environmental changes, human activities, and the threat of future pandemics.

The concept of Disease X, introduced by the World Health Organization (WHO) in 2018, underlines its potential to emerge from diverse sources. Here are key aspects and examples related to Disease X:
Zoonotic Viruses: Disease X can emanate from various sources, including hemorrhagic fevers and recent non-polio enteroviruses. Of particular concern is zoonotic transmission, where animal viruses jump to humans. This natural process presents a significant risk, necessitating awareness and preparedness. Increased animal-human interactions driven by globalization heighten the likelihood of new zoonotic diseases emerging and spreading globally.
H7N9 (2018): In 2018, a novel H7N9 “bird flu” strain emerged with a mortality rate of 38%, raising concerns akin to those of Disease X. However, it wasn’t officially recognized as Disease X by the WHO or the R&D Blueprint group. Initial reluctance to share samples by China added to concerns, but the outbreak was ultimately contained.
COVID-19 (2019-present): The COVID-19 pandemic prompted speculation about whether it met the criteria for Disease X. Notably, some experts suggested that Disease X might originate from a coronavirus. COVID-19 exhibited characteristics resembling a Disease X challenge due to its rapid global spread, according to experts.
Synthetic Viruses/Bioweapons: There have been speculations since 2018 that a future Disease X could potentially be intentionally created as a biological weapon, particularly through gene-editing technology’s capacity to produce synthetic viruses. While considered unlikely, the implications of such an event, enabled by synthetic biology, are grave.
Bacterial Infection (2019): In September 2019, Public Health England (PHE) expressed concerns about escalating antibiotic resistance in bacteria. Even last-resort antibiotics like carbapenems and colistin were losing effectiveness. This antibiotic resistance, exemplified by conditions like antibiotic-resistant gonorrhea, has the potential to evolve into a Disease X threat.

The specific source of the next potential Disease X pandemic remains uncertain. However, among the numerous virus families capable of infecting humans, six families- Adenoviridae, Coronaviridae, Orthomyxoviridae, Paramyxoviridae, Picornaviridae, and Poxviridae—stand out due to certain characteristics. These characteristics include:
No Immunity: There is no pre-existing immunity within the global population against these viruses.
Airborne Transmission: These viruses can be transmitted via respiratory means, contributing to their potential for rapid spread.
Silent Spread: Infected individuals can transmit the virus even in the absence of noticeable symptoms, which can facilitate stealthy transmission.
High Impact: There are no highly efficient medications or vaccines available to counteract the harmful effects of these viruses.
The caution raised by scientists aligns with the World Health Organization’s (WHO) prior prediction of an “inevitable” “Disease X” pandemic. The term was introduced by the WHO in 2018, preceding the COVID-19 pandemic. Within the WHO’s “Blueprint list of priority diseases” aimed at preparing for the next severe pandemic, notable entries include Ebola, SARS, and Zika.
The WHO has described “Disease X” as representing the recognition that a significant global epidemic could be triggered by a pathogen currently unidentified as causing human disease. The Blueprint list encompasses infectious diseases for which effective treatments are lacking. Some experts in public health express concerns that the next Disease X may have zoonotic origins, akin to diseases like Ebola, HIV/AIDS, and COVID-19.
In an ongoing effort, scientists are diligently monitoring 25 virus families, each comprising thousands of unique viruses. Among these, a subset holds the potential to evolve into severe pandemics. This surveillance, while extensive, does not extend to the monitoring of viruses capable of making the leap from animals to humans, thereby introducing an additional and unpredictable threat.
To enhance preparedness for future health crises, India should consider the following strategies:
Enhancing Healthcare Infrastructure: Continued investment in healthcare infrastructure, including hospitals, diagnostic laboratories, and research facilities, is crucial. A robust infrastructure ensures the availability of necessary resources and capacity to respond effectively to future outbreaks.
Improving Surveillance and Early Detection: Developing strong surveillance systems and early warning mechanisms is essential. Timely detection and containment of new diseases are critical in preventing their spread. Public awareness campaigns can play a role in educating the population about the signs and symptoms of emerging diseases.
Promoting Research and Development: India can leverage its robust pharmaceutical industry and scientific expertise to encourage research and development in infectious diseases, vaccines, and therapeutics. Such investments will strengthen the country’s ability to respond swiftly to novel threats.
Building a Skilled Workforce: A skilled healthcare workforce is indispensable for managing outbreaks effectively. India should focus on training and equipping healthcare professionals to ensure they are well-prepared to handle emergencies.
Fostering International Collaboration: Recognizing that Disease X is a global concern, India should actively engage with international organizations and participate in collaborative efforts. Sharing knowledge, expertise, and resources on a global scale enhances preparedness and response capabilities, contributing to global health security.
The concept of “Disease X,” as coined by the World Health Organization (WHO) in 2018, serves as a stark reminder of the potential for a devastating global pandemic triggered by an unknown pathogen. This concept underscores the inherent unpredictability of infectious diseases and underscores the urgent need for readiness and international collaboration within the realm of public health. Scientists and healthcare experts alike harbor deep concerns regarding the prospect of such an outbreak, highlighting the imperative of robust preparation and cooperation on a global scale.
Several key factors heighten the risk associated with Disease X. Factors such as climate change, increased interactions between humans and animals, and the growing menace of antibiotic resistance all contribute to the potential for a catastrophic event. These factors create an environment conducive to the emergence and rapid spread of novel pathogens, further complicating our ability to respond effectively.
In light of these challenges, a comprehensive approach is imperative. This approach must encompass vigilant monitoring of a diverse array of viruses, the fortification of healthcare infrastructure, improved disease surveillance capabilities, the promotion of research initiatives, and the cultivation of a skilled healthcare workforce. The collective and active collaboration of nations and international organizations is paramount in our quest to mitigate the unpredictable nature of Disease X and to fortify global health security. Only by working together can we hope to minimize the impact of potential pandemics and safeguard the well-being of populations worldwide.
