If you are a temporary resident in the United States, How can you receive health services or insurance?

I know someone who came from haiti to the USA after the earthquake and she is sick. Is there a program or way she can receive health services for free or even temporary Health insurance that will cover her bills? Is there a health insurance that comes with temporary resident visas?
