In the final paragraph, the phrase "Global pandemic" is redundant. A pandemic is, by definition, global. When a disease is declared to be a pandemic, it means that there are cases of that disease on every continent of the world, thus it is global. Pandemic does NOT mean "Zombie Apocalypse".
I'm sorry but you are sort of incorrect in your definition... depending on whom you ask,
Merriam Webster defines a pandemic as :"
an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population."

That doesn't mean global.
The Oxford dictionary also defines it as "
a disease that spreads over a whole country or the whole world".

Again not global just a very large area.
The WHO uses the term to mean it is global... but even the term 'global' isn't what one may think. For example
in a WebMD article they cite a WHO spokesperson:
"A pandemic is basically a global epidemic -- an epidemic that spreads to more than one continent," says Dan Epstein, a spokesman for the Pan American Health Organization, a regional office of the World Health Organization.
Spreading to more than one continent, say North and South America only, isn't truly global though as it leaves out Africa, Europe and Asia. To be truly global it should affect these continents as well.
