"Human trafficking is the use of force, fraud or coercion to exploit someone for labor or commercial sex. Any minor exploited for commercial sex is a victim of human trafficking. Thousands of men, women and children are trafficked in the United States every year. Many of these victims are lured from their homes with false promises of well-paying jobs; instead, they are forced into prostitution, involuntary domestic servitude, farm or factory labor, or other types of forced labor. Approximately one-third of human trafficking victims are treated by medical providers. Similar to observing patients for signs of abuse, fire and emergency medical service responders should be aware of the signs of human trafficking."
