Which statements concern pandemics? choose all that apply.

confined to a specific geographic area
easily spread to new areas
highly contagious disease
the bubonic plague
the common cold

Pandemics is the worldwide spread of a new disease.
Having this in mind, the statements that concern it are easily spread to new areas (via different viruses), highly contagious disease (many people can easily contract it), and the bubonic plague (which killed millions of people).
The first option is incorrect, because pandemics easily spreads all over the world, and the common cold is not pandemic.
