All day and sometimes into the night, buses and vans pull up to three state-funded medical screening centers near California’s southern border with Mexico. Federal immigration officers unload migrants predominantly from Brazil, Cuba, Colombia, and Peru, most of whom await asylum hearings in the United States.
Once inside, coordinators say, migrants are given face masks to guard against the spread of infectious diseases, along with water and food. Medical providers test them for the coronavirus, offer them vaccines, and isolate those who test positive for the virus. Asylum-seekers are treated for injuries they may have suffered during their journey and checked for chronic health issues, such as diabetes or high blood pressure.
