Even as Covid-19 is seeing a decline, the World Health Organisation (WHO) has warned of the threat of an “inevitable” next pandemic of “Disease X”, raising concerns across the globe. Disease X was first coined in 2018 by the WHO, a year before the Covid-19 pandemic struck the world. It is among the WHO’s “Blue print list priority diseases” that could cause the next deadly pandemic and includes Ebola, SARS, and Zika.
