The unaccompanied teen died on Tuesday after "several days of intensive care" at a children's hospital, the U.S. Department of Health and Human Services (HHS) said in a statement.

He entered the United States near the border city of El Paso, Texas and was detained by U.S. border patrol agents on April 19, according to a statement from Guatemala's foreign ministry.

The boy was then sent to shelter nearly 700 miles (1,130 km) away in Brownsville, the statement added, where he was "beginning the process of family reunification."

He ultimately underwent surgery to relieve pressure in his head, according to the ministry.

The unnamed teen was from Camotan, a town near Guatemala's border with Honduras known for high levels of malnutrition among a mostly poor population that ekes out a living as farmers.

The boy's death follows those of two other Guatemalan migrant children in December and warnings from U.S. officials that more tragedies were likely given the surge in migrants crossing the border, and serious illnesses encountered among them.

The teenager was transferred on April 20 from Immigration and Customs Enforcement (ICE) custody to the Brownsville shelter run by the Office of Refugee Resettlement, which houses migrant children.

"Upon arrival to the shelter the minor did not note any health concerns," the U.S. government statement said.

The next morning the boy "became noticeably ill including fever, chills and a headache," according to the statement.

Shelter staff took the teen to a hospital emergency department that morning where he was treated and released to the shelter the same day, the statement added.

The boy's health did not improve and the next day he was taken to another hospital emergency department by ambulance. Later that day he was transferred to a children's hospital's intensive care unit in Driscoll, Texas, where he stayed for several days before he died.

The boy's brother and Guatemalan consular officials visited him while he was in hospital and his family in Guatemala was regularly advised of his condition.

Opponents of United States President Donald Trump's immigration policies, including Democrats in Congress, have called for better medical screening in border facilities to detect such cases sooner and prevent deaths.

After the December fatalities, the Trump administration announced policy changes to help prevent the deaths of children in custody, including more thorough medical checks

The U.S. officials said the cause of the teenager's death is under review and the case will be subject to a full review.
