WHO Warns Next Pandemic Could Dwarf COVID-19: ‘Disease X’ Looms
Table of Contents
The world may be emerging from the acute phase of the COVID-19 pandemic, but leading health experts at the World Health Organization (WHO) are sounding the alarm about a far graver threat on the horizon – a potential “Disease X” that could trigger a global catastrophe exceeding the scale of the recent crisis.
Meta Description: WHO experts warn of ‘Disease X,’ an unknown pathogen with pandemic potential, and the growing risks from viruses like Bird Flu and Henipavirus.
The COVID-19 pandemic, which claimed approximately 1.2 million lives globally, is now viewed by some as a mere “warning shot,” according to reports stemming from a recent BBC investigation. Even as a new COVID-19 variant spreads across the United Kingdom, the focus is shifting to identifying and preparing for the next inevitable pandemic threat.
The Shadow of ‘Disease X’
The WHO first coined the term “Disease X” in 2018 as a placeholder for an unknown pathogen with the potential to cause a serious global pandemic. While COVID-19 initially fit this description, experts emphasize that it is not the only potential candidate. A senior official explained, “Disease X is a term that we coined to describe an unknown pathogen, one with the potential to cause a serious global pandemic.”
Investigations led by Dr. Chris Van Tulleken, documented in the BBC film Disease X: Hunting the Next Pandemic, reveal that WHO experts are actively monitoring disease outbreaks across Africa, Asia, and the Americas. These outbreaks, while currently localized, possess the potential to escalate into widespread harm, with some exhibiting alarmingly high mortality rates.
For example, an avian flu outbreak in Vietnam, despite only 129 confirmed cases, resulted in 65 deaths. Similarly, Yellow Fever cases in Bolivia, Brazil, Colombia, Ecuador, and Peru have demonstrated a significant fatality rate, with 56 deaths reported from 144 cases.
Emerging Threats: Bird Flu and Henipavirus
Beyond the unknown, specific pathogens are raising significant concerns. The H5N1 bird flu, which has recently spread to cows on a Texas ranch and infected farm workers and veterinarians, is described as being “closer to pandemic potential than it’s ever been before.” While the best-case scenario involves the virus mutating into a harmless form, the worst-case scenario – a highly lethal and contagious strain – remains a very real possibility. Concerns have also been raised regarding the potential contamination of millions of gallons of raw milk with the virus, though no serious illnesses have been reported to date.
Another virus drawing attention is the Henipavirus. This virus, which “destroyed” a village in Malaysia in the 1990s after jumping from pigs to humans, carries a fatality rate between 40% and 75%. Recent findings of the virus in Australian bats have heightened fears of potential airborne transmission.

The Speed of Global Transmission
Experts acknowledge that viruses naturally tend to become less dangerous over time, as less-lethal strains proliferate. However, the speed of modern global air travel presents a critical challenge. A deadly pandemic could easily spread internationally before the natural decline in a disease’s threat level can take effect.
“The next ‘Disease X’ could come from anywhere,” warned a WHO representative, “and cause mass deaths before experts can react. What could result, could make the Covid-19 pandemic look mild.” The threat isn’t limited to viruses; bacteria and fungal infections also pose a significant risk. The next pandemic could be a mutated version of a known pathogen or, more frighteningly, a completely new entity – “one that we’ve never even imagined.”
The Role of Modern Farming
The increasing interaction between livestock and humans is also contributing to the risk. Modern farming practices, according to experts, are creating more opportunities for diseases to jump species. The WHO regularly conducts simulations to prepare for potential pandemic scenarios.
The organization’s constant monitoring and proactive approach are crucial, but the ultimate outcome remains uncertain. As one expert stated, “We are watching every day in the hope that we can warn us all before it’s too late.”
