The outbreak has been ongoing since then, with 2,578 confirmed and probable EVD cases and 1,737 deaths reported as of July 20, 2019. Large (>1 million population) cities have also been affected, including Goma, which is on the border with Rwanda. Cases have also occurred in Uganda, but no local transmission has occurred there.

, the World Health Organization declared a Public Health Emergency of International Concern (PHEIC) for EVD in the DRC.

Therefore, a best practice continues to be for healthcare providers in hospitals, emergency departments and clinics to routinely ask patients with acute and possibly infectious illness about recent international travel.
