Disease X Situation in UK
UK healthcare professionals are preparing for a potential new pandemic known as ‘Disease X,’ which could be more deadly than COVID-19, with the capacity to result in 20 times more fatalities. Disease X could potentially cause up to 50 million deaths.

They caution that this new virus could have a similar impact to the devastating Spanish Flu of 1918-1920.

In response to Disease X, the world will have to prepare for mass vaccination drives and deliver the doses in record time.
