WASHINGTON/NEW YORK (Reuters) - The United States and Canada closed their shared border to "non-essential traffic" on Wednesday to curb transmission of the coronavirus as U.S. President Donald Trump moved to bolster medical equipment supplies and the outbreak struck Capitol Hill.

Two members of the U.S. House representatives - Mario Diaz-Balart of Florida and Ben McAdams of Utah - said on Wednesday they had each tested positive for coronavirus, becoming the first lawmakers in Congress known to have become infected.
