The number of uninsured Latinos has drastically decreased over the past few years, but they still remain to be the racial and ethnic group with the highest uninsured rates in the U.S. To date, only four million Latinos have signed up for health insurances via the Affordable Care Act of 2010, more commonly known as ObamaCare.

The Obama administration is now encouraging uninsured Latinos to start flocking enrollment centers so they can shop for coverage and get signed up.

"The Latino community still suffers from health disparities like disproportionate rates of asthma, diabetes and certain cancers," Health and Human Services Secretary Sylvia Mathews Burwell told NBC News. "But with better access to better checkups, diet counseling and many cancer screenings, we can begin to close these gaps."

As part of the third Latino Week of Action, signing up for insurance begins this Saturday, Jan. 31.The enrollment period ends on Jan. 31.

Enroll America is working diligently to help spread awareness about subsidies available to people who qualify financially. A recent study conducted by the Urban Institute showed that four out of five Latinos did not know about the federal assistance.

Anne Filipic, president of the non-profit organization, said they are now implementing the most effective tactics to reach Latinos -- in-person assistance in English or Spanish.

To speed up the process, Enroll America has created an online tool called the Get Coverage Connector, which lets people set up appointments for in-person assistance in either English or Spanish.

Around 15 groups have joined to help uninsured Latinos get health coverage, including the League of United Latin American Citizens, the National Association of Hispanic Nurses and Planned Parenthood Federation of America.

Port Richmond resident Maria Farias, who hails from Paraguay, has been living without health insurance since 2011, the year her husband lost his job. She gets her medical treatment from a nearby public center where she pays $10 as consultation fee for the doctor. She said she couldn't afford $300 a month for health insurance.

"I'm still thinking about how I can get health insurance," Farias told Philly during a festival celebrating the Feast of Our Lady of Guadalupe. "I'm just afraid it's not going to be as affordable as they say."

The cost of health care rises per year. Contrastingly, coverage has been decreasing. This phenomenon leaves a greater portion of the doctor's bill to the patients. Those who plan to sign up for health insurance are advised to know the limits of their coverage before using it. No one wants to start the year with a terrible case of sticker shock from a steeply priced doctor's bill.
