Title 42 expulsion

Title 42 expulsions were removals by the U.S. government of people who had recently been in a country where a communicable disease was present. The extent of authority for contagion-related expulsions is set out by law in 42 U.S.C. § 265. During the COVID-19 pandemic, the Trump administration used this provision to generally block land entry for many migrants. This practice was initially continued by the Biden administration before the program was ended with the end of the COVID-19 national emergency in the United States. Title 42 of the United States Code includes numerous sections dealing with public health, social welfare, and civil rights, but, in the context of immigration, the phrase "Title 42" came to be used to refer specifically to expulsions under section 265.
