Unveiling the Threat of Disease X: Preparing for the Next Global Pandemic

The term “Disease X”, first introduced by the World Health Organization (WHO) in 2018, symbolizes the threat of an unknown pathogen capable of causing a global pandemic. Classified as a “priority pathogens,” Disease X stands alongside well-known threats like SARS, Ebola, and ZIKV due to its potential for widespread outbreaks. SARS-CoV-2 is considered the first “Disease X” to fulfill this prediction, demonstrating the devastating impact such pathogens can have. A future pathogen X could pose an even greater threat, with catastrophic consequences. This paper examines the potential origins of such pathogens, drawing lessons from outbreaks like SARS, MERS, and SARS-CoV-2. It also highlights strategic approaches to detect, prevent, and respond effectively to mitigate the risk of future pandemics.
