Uganda has closed its border with the Democratic Republic of the Congo to contain the spread of the rare Bundibugyo strain of Ebola, after Ugandan health workers were exposed to infected patients crossing from Congo. The outbreak, now confirmed in both countries, has led to 121 cases and 17 deaths in Congo, and seven cases including one death in Uganda. The World Health Organization discourages border closures, warning they may drive movement through unmonitored routes and increase transmission risk.

The Bundibugyo strain, less common than other Ebola variants, currently has no approved vaccines or treatments. The outbreak in eastern Congo was confirmed late, after initial testing focused on more common strains. Compounding the crisis are armed conflict, displacement, and weak health infrastructure in the region. WHO’s Director-General has called for a ceasefire to allow safe access for health responders.

Meanwhile, the U.S. has restricted entry for travelers from affected regions, requiring enhanced screening at select airports. American citizens returning from Congo, Uganda, or South Sudan must enter through one of four designated U.S. airports. Green card holders and foreign nationals from these countries are currently barred from entry. The U.S. is setting up a monitoring facility in Kenya for exposed citizens, as six Americans are already under observation in Europe.
