Ebola Outbreak Threatens Global Spread, Health Chiefs Warn

Africa's top health official has warned that the current Ebola outbreak could soon spread globally, placing Europe on high alert as cases surpass 10,000 and deaths reach 5,000.

Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention, described the geographic spread of the virus as "unprecedented" and urged all countries to increase their preparedness levels and treatment capabilities. He drew a parallel to the early days of the COVID-19 pandemic, when some nations believed they would be unaffected.

The virus was first detected in May in the Democratic Republic of Congo and has primarily been confined to African nations including Uganda, Kenya, and Nigeria. However, Kaseya cautioned that "no country is safe if they don't take appropriate measures."

Experts acknowledge the risk of Ebola reaching other continents, including the UK. Dr. Paul Hunter, a professor of medicine at the University of East Anglia, stated that transmission could occur from an imported case at any time, though he emphasized that Ebola is not highly transmissible and typically requires close contact with bodily fluids.

"The fact is that Ebola is not that transmissible and usually requires close contact with a case or their body fluids," Hunter said. "Furthermore, the infectiousness of a case increases as the case becomes more ill and especially as they approach death."

He noted that in countries like Britain, patients would likely be identified and hospitalized before infecting large numbers of people, making the risk of becoming an "Ebola hotspot" very low, though "nothing is impossible."

Dr. Charlotte Houldcroft, an assistant professor of virus genomics at the University of Cambridge, pointed out that infected travelers can carry the virus for up to three weeks before symptoms appear. "People can be exposed abroad, travel feeling well, but be incubating an infection that they fall ill with once back in the UK," she explained. The incubation period for Ebola normally ranges from 8 to 10 days but can extend to 21 days.

Despite these concerns, Houldcroft believes the UK would be prepared to manage any cases, stating, "This isn't a situation like Covid." She noted that Ebola generally spreads more slowly than COVID-19, allowing time for contact tracing and other measures to be implemented.

Professor Sir Andrew Pollard, a professor of infection and immunity at the University of Oxford, agreed that concern is warranted but also expressed confidence in the UK's ability to identify cases.

This warning comes after a Swiss woman contracted Ebola in Nigeria and received treatment in West Africa before being transferred to Geneva. France has also reported a case of a doctor returning from the DRC. In Britain, a suspected Ebola case in June led to a precautionary shutdown of a section of Glasgow's Queen Elizabeth University Hospital, though the patient later tested negative.

The current outbreak is driven by a rare strain called Bundibugyo, which has a fatality rate of up to 50 percent. It spreads through direct contact with the blood or bodily fluids of an infected person or through contaminated surfaces. A vaccine for Bundibugyo is currently under development, with trial results anticipated in three to six months.

This outbreak is the largest in the DRC's history and the second-largest overall, surpassed only by the 2014-2016 epidemic that caused over 28,000 cases and 11,000 deaths across West Africa. Symptoms of Ebola include flu-like fever, headache, muscle pain, vomiting, and diarrhea, which can progress to internal bleeding, organ failure, and death. The Bundibugyo strain was first identified in 2007 and has had previous smaller outbreaks in Uganda and the DRC.
