British doctor who has tested positive for Ebola after working in DR Congo arrives back in the UK for treatment at London hospital

A British doctor who tested positive for Ebola after working in the Democratic Republic of Congo has returned to the UK for specialist treatment.Pictures showed ambulances understood to be carrying the patient arriving at London's Royal Free hospital this evening.The doctor, said to be in a stable condition, will be taken to the hospital's infectious disease unit for treatment.It marks the first time a Briton has tested positive for Ebola in the current outbreak.More than 5,000 people have now died in this outbreak with cases passing 10,000, most of which were found in the DR Congo.A rare strain of the disease which can kill up to 50 per cent of those it infects, called Bundibugyo, has driven the latest spread. There is currently no vaccine for the deadly strain but scientists have begun clinical trials for a jab.Ebola symptoms include a flu-like fever, headache, muscle pain, vomiting and diarrhoea before progressing to internal bleeding, organ failure and often death.

The patient later tested negative.The following month, a suspected Ebola case was being monitored at a London hospital after a humanitarian worker was 'exposed' to the disease in the DRC.Just last week, however, Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention, said the 'geographic extension of this outbreak is unprecedented' and warned that health officials worldwide must be prepared.'We want all countries to know that they are not safe if they don't take appropriate measures,' he said.'Each country, not only in the African region, but all continents, must now increase the preparedness level and the possibility for treatment.'Dr Kaseya compared the current situation to countries thinking they would not be affected by Covid before the pandemic struck.'We don't want to see the UK and other countries become a hotspot,' he added.Experts said that Britain could be at risk of the virus arriving undetected for weeks – and that Dr Kaseya is 'right to be concerned'.'There have been several cases already in Europe from this epidemic,' said Dr Paul Hunter, professor of medicine at the University of East Anglia.

Jean Kaseya, director general of the Africa Centres for Disease Control and Prevention, warned last week that Britain is 'not safe' from the 'unprecedented' Ebola outbreak'Ebola typically spreads a bit more slowly than [Covid], giving measures like contact tracing time to catch up with suspected cases.'Sir Andrew Pollard, a professor of infection and immunity at the University of Oxford, said Dr Kaseya is 'right that we should all be concerned'.But he agreed with Dr Houldcroft that the UK would be well equipped to identify cases.The origin of the Bundibugyo strain is unknown but some researchers believe it was passed on to humans by fruit bats.It was first recorded in 2007 and takes its name from the area of western Uganda where it was found.A second outbreak started in the DR Congo in 2012 but both epidemics were smaller, with estimates suggesting around 200 cases and 66 deaths. The current outbreak is the largest in the DR Congo's history and the second-largest ever, behind a major spread between 2014 and 2016 that caused more than 28,000 cases and 11,000 deaths across West Africa.A Foreign Office spokesman said today: 'A British citizen currently in ‌the DRC has tested positive for Ebola.'​The risk ⁠to the UK ⁠public from Ebola ​remains low.'
