The infection of a responding doctor illustrates the occupational risk borne by those on the front line of outbreak control.
A British doctor who tested positive for Ebola while working in the Democratic Republic of the Congo has been evacuated to the UK for specialist treatment, according to The Guardian. The patient, whose identity has not been disclosed, was flown home on a medical evacuation flight, the Department of Health and Social Care said on Thursday, and is now being cared for in a specialised high-level isolation unit at the Royal Free hospital in Hampstead, north London.
The doctor had been sent to DR Congo by a humanitarian organisation to help in the response to the outbreak, which the newspaper describes as the second largest on record. It is the first case involving a British national contracting Ebola in the current outbreak. The Royal Free's isolation unit operates strict protocols to prevent contact between the patient and members of the public, and staff treating the patient are equipped with personal protective equipment alongside other measures to prevent transmission.
Dr Renu Bindra, deputy director for all-hazards public health response at the UK Health Security Agency, said that UKHSA and the NHS have well-established and robust infection prevention and control protocols to limit the risk of onward transmission, and that the risk to the wider public remains low. That assessment is the central point of reassurance in the official response, and it rests on the nature of the disease: Ebola spreads through direct contact with the body fluids of infected people, or with dead bodies, rather than through the air. People with the disease tend to fall ill two to 21 days after contact with an orthoebolavirus, with initial symptoms including fever, aches, pains and fatigue that can progress to diarrhoea, vomiting and unexplained bleeding.
The wider context is more troubling. The outbreak was declared in May by DR Congo's health ministry and has surpassed 10,000 cases and 5,000 deaths, according to the report. It has spread to Kenya and Uganda in east Africa, and last month Nigeria confirmed a case in its capital, Abuja. A caseload of that size, spanning several countries, places heavy demands on local health systems and on the humanitarian workers sent to support them. The infection of a responding doctor illustrates the occupational risk borne by those on the front line of outbreak control.
For the UK, the case is a rare one. There have been only four previously confirmed cases of the virus in the country: one in 1976 from a laboratory needle incident, and three involving health workers responding to the outbreak in West Africa between 2014 and 2015. The arrival of a patient on British soil is therefore a significant event for the health service, even as officials stress that the isolation arrangements are designed to contain it.
What is not yet known is how the doctor was infected, what their current condition is, or which humanitarian organisation employed them; the report does not say. Nor is it clear whether the evacuation will prompt any change in the deployment of British medical personnel to the region. Those questions will shape how the case is understood in the coming days, but the public health position set out by the UKHSA is that onward transmission is being actively guarded against and that the risk to the wider public remains low.
