At the recent World Economic Forum, the World Health Organization issued a warning to world leaders, saying the world could face a pandemic 20 times worse than COVID-19 in the future.

Scientists call it Disease X, a term that recognizes the next global pandemic could come as the result of an unknown pathogen rather than the spread of a currently recognized disease.

Without preparedness, the WHO warned, a pandemic from Disease X could cause much more damage than COVID, which has killed more than 7 million worldwide.
