Migrants who have crossed the U.S.-Mexico border and travel to cities around the country are running into a disjointed health care systems when they need treatment. There is no national system to track the medical care that new arrivals may have received.

Doctors also say they struggle to keep track of patients because of unstable or fluid housing situations.
