A recent confirmation of an Ebola case in France, involving a doctor who had been working in the Democratic Republic of Congo (DRC), has prompted commentary from UK scientists who are reassuring the public about the minimal risk of wider spread. The individual, a healthcare worker, was quickly identified, isolated, and is now receiving treatment, a process crucial for containing the virus.
Professor Paul Hunter, Professor in Medicine at the University of East Anglia (UEA), highlighted that healthcare workers are among the most vulnerable groups in any Ebola outbreak. He noted that it is not uncommon for expatriate health workers to potentially bring the infection back with them, either during repatriation if they fall ill or if they are incubating the disease when their assignment concludes. Given the scale of the ongoing outbreak in the DRC, such an imported case is not surprising.
However, Professor Hunter also underscored the rarity of such imported cases leading to onward transmission within Europe. He cited only three previous instances of Ebola being acquired from contact with infected patients outside Africa, all occurring during the significant West African epidemic in 2014. These involved a nurse in Spain and two individuals in Texas, all of whom were directly caring for infected patients.
Professor Jonathan Heeney, Professor of Comparative Pathology of Viral Infections and Head of the Lab of Viral Zoonotics at the University of Cambridge, echoed this sentiment, stating that similar cases have been observed in past Ebola outbreaks. He emphasised that the Bundibugyo strain of Ebola, like other strains, spreads exclusively through close contact with bodily fluids. With stringent precautions and monitoring in place, the risk to the public is deemed very low, especially when compared to more easily transmissible airborne viruses like influenza or COVID-19.
Dr Daniela Manno, Clinical Assistant Professor at the London School of Hygiene & Tropical Medicine (LSHTM), reinforced that while this is the first reported case in Europe linked to the current Bundibugyo outbreak, its detection is not entirely unexpected. She pointed out the challenges in case identification and contact tracing in some affected areas of the DRC, which can mean infected individuals may seek healthcare before their exposure is recognised. European nations, however, possess well-established protocols for identifying and managing suspected cases of viral haemorrhagic fever, significantly mitigating the risk of wider transmission.
Professor Jonathan Ball, Deputy Vice-Chancellor and Professor of Molecular Virology at the Liverpool School of Tropical Medicine, also commented on the inherent risks faced by frontline healthcare workers. He explained that in the absence of specific vaccines, these professionals rely entirely on personal protective equipment and rigorous clinical practices to prevent exposure, and unfortunately, breaches can sometimes occur. He reaffirmed that the risk to the broader community in France remains low due to immediate isolation and tracing efforts.
