President Yoweri Museveni of Uganda has added 21 days to the quarantine imposed on the two regions at the center of the nation’s Ebola outbreak and stated that the government’s response to the disease was working.

Up until December 17, access to and from the central Ugandan regions of Mubende and Kassanda would be limited, the presidency announced late on Saturday. On October 15th, it was imposed for 21 days, and on November 5th, it was extended for the same amount of time.

The extension were “to further sustain the gains in control of Ebola that we have made, and to protect the rest of the country from continued exposure.”

The government’s anti-Ebola efforts were succeeding with two districts now going for roughly two weeks without new cases, the president said.

“It may be too early to celebrate any successes, but overall, I have been briefed that the picture is good,” he said in a statement.

The East African nation has so far recorded 141 infections. Fifty-five people have died since the outbreak of the deadly haemorrhagic fever was declared on Sept. 20th.

Although the outbreak was gradually being brought under control, the “situation is still fragile,” Museveni said, adding that the country’s weak health system and circulation of misinformation about the disease were still a challenge.

The Ebola virus circulating in Uganda is the Sudan strain, for which there is no proven vaccine, unlike the more common Zaire strain, which spread during recent outbreaks in neighbouring Democratic Republic of Congo.
