How does a past pandemic behave like the current coronavirus pandemic?

1st many people died and it was even contagious like the black pledge so people wear mask people had to quarantine to spread by people traveling alot.

hello,

answer: a federal government has final authority on interstate/inter provincial  and international affairs, a confederation is one where the central/national government or authority is governing body what does not have final say over the same matters. hopefully this and i will try again if you don't like this answer : )

best of luck!
