US health officials can now formally block travelers from specific countries

The US health department just created a formal process to stop people from entering the country from specific places. This means the Secretary of Health, through the CDC, can now quickly suspend travel for public health reasons.

This rule formalizes the power of US health officials to restrict international travel during public health emergencies. It defines the specific steps the Secretary of Health and Human Services must follow to block people from entering the country. This clarifies how the government can act in future pandemics or outbreaks, making such actions more predictable and legally robust.
