Uganda will close schools nationwide later this month after 23 Ebola cases were confirmed among pupils, including eight children who died, the country's first lady said on Tuesday.

Janet Museveni, who is also the education minister, said there had been cases in five schools in the capital Kampala, as well as the neighboring Wakiso district and Mubende, the epicenter of the outbreak.

She said the cabinet had agreed to close pre-primary, primary, and secondary schools from 25 November, two weeks before the scheduled end of term.

"Closing schools earlier will reduce areas of concentration where children are in daily close contact with fellow children, teachers, and other staff who could potentially spread the virus," said the minister and wife of veteran President Yoweri Museveni.

On Saturday, Uganda extended a three-week lockdown on Mubende and neighboring Kassanda, the two central districts at the heart of the outbreak which has claimed more than 50 lives.

The measures include a dusk-to-dawn curfew, a ban on personal travel, and the closure of markets, bars, and churches.

Since the outbreak was declared in Mubende on 20 September, the disease has spread across the East African nation, including to the capital Kampala.

But the president has said nationwide curbs were not needed.

According to government figures dated 6 November, a total of 53 people have died of Ebola out of 135 cases.

The World Health Organization last week said Uganda had registered over 150 confirmed and probable cases, including 64 fatalities.

Uganda's last recorded fatality from a previous Ebola outbreak was in 2019.

The strain now circulating is known as the Sudan Ebola virus, for which there is currently no vaccine, although there are several candidate vaccines heading toward clinical trials.

Ebola is spread through bodily fluids, with common symptoms being fever, vomiting, bleeding, and diarrhea.

Outbreaks are difficult to contain, especially in urban environments.
