Not trying to be argumentative or contrarian but WHO not declaring that a pandemic is over is not really what signals the end of a pandemic (any pandemic, not just COVID). Most literature suggests that pandemics tend to end organically, once the culture(s) impacted return more or less to normal. The pandemic has been over by conventional definitions for a couple years now. That doesn't mean that COVID is less of a threat or shouldn't be taken seriously by any means. It just means that society is no longer adjusting daily life because of the threat.
