WESLACO, Texas — The U.S. Border Patrol continues to apprehend large numbers of undocumented migrant families at the southern border, including a surge of people arriving in poor health conditions that require hospitalization.

The agency said smugglers and traffickers have helped cross 53 groups of 100 or more undocumented migrants since October, most of them families and unaccompanied children.

One group of 247 people was apprehended in New Mexico two weeks ago, 50 of which required medical attention.

U.S. Customs and Border Protection's most recent data shows more than 2,200 migrants were taken to local hospitals, which is about 5.3% of all arrests at the southwest border since December 22.

That same month, Border Patrol agents reported two separate cases of Guatemalan children dying while in their custody. The latest case involved 8-year-old Felipe Gomez, whose body was repatriated to his rural hometown Sunday.

Last year saw a record of undocumented migrant families crossing the border, CBP warns 2019 could surpass that.
