In a controversial move, U.S. President Donald Trump has suspended foreign aid, cutting off vital supplies of treatments for HIV, tuberculosis, and malaria to some of the world’s most vulnerable regions, including South Africa.

This decision has raised alarms among health organizations and advocates who warn that millions of lives are now at risk.

Programs like the President’s Emergency Plan for AIDS Relief (PEPFAR), which have been instrumental in providing life-saving medications and support, are now effectively frozen.

The suspension of these programs leaves countless individuals who rely on these treatments in a precarious position, particularly in countries where healthcare systems are already strained.
