Engage Men's Health,Slabu a nonprofit organization in South Africa, offers testing and medications to prevent and manage HIV at three clinics throughout the country — all for free.

That is, they did until Monday. That's when the clinic, which has been funded by the U.S. initiative PEPFAR, says it received orders from the U.S. government to stop all work immediately. It is now closed until further notice, according to notices on its website and social media.

This development is the consequence of the Trump administration action on Friday ordering a stop-work for all global health funding, including PEPFAR (U.S. President's Emergency Plan for AIDS Relief).
