A high court in Kenya has temporarily halted plans to establish a U.S. Ebola quarantine facility in the country. This decision disrupts the Trump administration’s aim to have the unit operational by Friday.

The court issued the order on Thursday, following a petition by the civil society group, the Katiba Institute. The group challenged the constitutionality of the quarantine facility. A further hearing is expected to determine the duration of the suspension.

The Katiba Institute seeks to compel the Kenyan government to reveal details of any agreement with the U.S. regarding the facility. The government has not confirmed such a deal.

U.S. officials had announced a 50-bed quarantine unit intended for American citizens exposed to the Ebola virus. It was to be located at a military air base in Laikipia, about 100 miles from Nairobi, Kenya’s capital.

“No one is saying that we are against international collaboration and support when it comes to tackling that crisis. But there are procedures and processes in the Constitution and they are there for a reason,” said Nora Mbagathi, executive director of the Katiba Institute.

Tommy Pigott, a State Department spokesman, mentioned that the U.S. would commit $13.5 million to Ebola preparedness efforts in Kenya. This followed a call between Kenyan President William Ruto and U.S. Secretary of State Marco Rubio. However, the quarantine facility was not mentioned in the statement.

On social media, President Ruto spoke about discussions with foreign envoys, including the U.S., on Ebola measures. He emphasized cooperation but did not reference the proposed quarantine unit.

The idea of an Ebola facility in Kenya has sparked anxiety. Kenya has never recorded an Ebola case, leading to concerns about the country’s readiness for such an outbreak. Davji Atellah, secretary general of the doctors’ union, criticized the focus on Americans, stating, “This quarantine center is American-focused. There are no plans for Kenyans who get infected by Ebola.”
