Officials say federally run health exchange has signed up 7.5M; state markets have 2.4M

The Obama administration says sign-ups continue to build under the president's health care law ahead of a Feb. 15 enrollment deadline.

Nearly 7.5 million people enrolled as of last Friday in 37 states where the federal government is running insurance markets, which offer subsidized private coverage for people who don't have a job-based plan.

South Florida led other major metro areas, with more than 637,000 people enrolled from Miami to West Palm Beach.

Additionally, states acting in tandem with the federal site have signed up at least 2.4 million people through their own insurance exchanges.

Officials are preparing for a surge toward the end of next week, as supporters make a final push.

The goal is at least 9.1 million people enrolled and paying premiums for 2015.
