According to reporting from Reuters, Kenya has confirmed its first Ebola case after a Kenyan citizen who traveled from the Democratic Republic of the Congo died on Monday.

Kenya is now the fourth country to record a case linked to the current outbreak in the DRC. The patient had been ill for about a month before traveling by road from the DRC to Uganda's capital, Kampala, and then flying to Nairobi on Saturday. He passed through health screening in Nairobi and was quickly placed in isolation, but died two days later. 

The incident has raised questions about measures meant to prevent the spread of the virus across borders. Officials suspect medication may have masked the patient's symptoms, allowing him to pass undetected through airports. 

Another report from Reuters stated that the itinerary required travel across the border of Congo and Uganda, which has been closed since May. This goes to show how porous the borders are between the countries and how difficult screenings can be when Ebola symptoms are at early stages and not so easily detectable. Travelers can also choose not to disclose symptoms when filling out health declarations or undergoing virtual assessments.
