Health insurance sign-up deadline is Jan. 31

Time is running out for people looking to sign up for health insurance under the Affordable Care Act.

The deadline to purchase policies is Sunday.

People who can afford to buy insurance this year, and choose not to, could face a hefty fine.

State officials are urging people to get covered.

Three in four people who sign up for insurance get some financial assistance in paying their premiums, the U.S. Department of Health says.
