Africa's unprecedented Ebola outbreak could reach the UK, health official warns

Africa's top public health body has warned that the current Ebola outbreak could spread beyond the continent, including to the UK, as the number of confirmed cases has reached 10,000 and deaths have climbed to almost 5,000. Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention, said the geographic spread of the outbreak was unprecedented and that three African regions have now been affected. He said countries outside Africa should not assume they are safe unless they strengthen preparedness and treatment capacity.

Kaseya compared the situation with the early stages of Covid-19, saying some countries initially believed they faced no risk before the virus spread widely. He said the outbreak is now the first time Ebola has affected three African regions, underlining the scale of the current emergency. His warning came as health authorities across the region continue to track transmission and assess the risk of further cross-border spread.

The outbreak is the 17th Ebola outbreak in the Democratic Republic of the Congo since the disease was identified there, and officials say it is the largest and deadliest in the country's history. It is caused by the Bundibugyo virus, which can spread through direct contact with infected body fluids or with dead bodies during funeral preparations. The health ministry in the Democratic Republic of the Congo declared an outbreak in Ituri province on 15 May, although sequencing indicates it began in February.

The disease has now spread to Kenya and Uganda in east Africa, while Nigeria confirmed a case in Abuja last week after a woman who had arrived from Uganda tested positive. France is the only non-African country to have confirmed a case so far, involving a doctor who had returned from the region. The latest warning from Africa CDC raises the possibility that more countries may need to prepare for imported cases if transmission continues.

The warning is significant because Ebola outbreaks can place severe pressure on fragile health systems and require rapid tracing, isolation and infection control measures. Kaseya said the current situation should prompt governments on every continent to increase preparedness and the possibility of treatment. His comments also reflect concern that delayed action could allow the outbreak to move further across borders, as happened with other major infectious disease emergencies.

What remains unclear is how far the outbreak may spread and whether current containment measures will be enough to slow transmission. It is also not yet clear how many countries may ultimately be affected or whether additional cases will be detected outside Africa. The next developments to watch are new case reports, any further international spread, and whether governments respond with stronger surveillance and preparedness measures.
