I’d like to share with you a possible scenario. A way in which they may create a new pandemic and call it bird flu. I got this idea from reading Mark 13 v 14-19

A warning is given that people should stay in high places and away from populated areas such as cities.

I have often wondered why people are warned to stay on the roof top and not go down stairs.

I am guessing that some kind of airborne toxin is deployed that is heavier than air so it may form a low lying mist like a fog. It makes sense that it is heavier than air since then it will settle at ground level and not disperse into the atmosphere.

It may be only deployed over cities rather than rural areas.

Areas high up such as mountainous areas may be less effected because the mist is denser than air so will settle in lowlands .

This is just speculation, but I feel obligated to share this idea.
