The extent of the impacts of the Trump administration’s sudden 90-day freeze of almost all foreign aid is still unclear almost a week on, as officials and aid workers overseas try to make sense of which activities must be suspended.

Secretary of State Marco Rubio backtracked on Trump’s near-total foreign aid freeze and approved potentially billions of dollars in “life-saving humanitarian assistance.” Many aid groups are still unsure what that means.

Patients and health care advocates said the abrupt decision to halt U.S. funding for a lifesaving H.I.V. program led to widespread confusion. The backtracking didn’t help.
