Ebola is one of those diseases you’d rather not know about. It has a high mortality rate, often over 50%, and while the symptoms start with a fever and headache, in the latter stages, the body internally bleeds to death. Because it’s spread through body fluids, such as an infectious person’s blood, vomit, urine, saliva, sweat or semen, it’s not as infectious as respiratory pathogens such as Covid-19, which spread through air. Those most at risk of Ebola are healthcare workers and family members caring for their sick loved ones. Uganda is currently battling one of its largest outbreaks of Ebola. The Ugandan outbreak is caused by the Sudan strain of the virus, for which there are no approved vaccines or treatments. This is why the new outbreak is particularly concerning public health experts. As with Covid-19, the race is now on to find an effective vaccine: there are two potential candidates from GSK and Oxford, and clinical trials are being launched in the middle of this outbreak. The head of the World Health Organization, Tedros Adhanom Ghebreyesus, said there have already been 63 confirmed Ebola cases and 29 deaths. Four of those dead were health workers. Cases were first detected in the Mubende district among people living around a goldmine. Gold traders are highly mobile, particularly along the busy highway that runs between Kampala, a densely populated and globally connected capital of 1.68 million people, and the Democratic Republic of the Congo to the west. Countries have already started implementing surveillance measures; the United States has started redirecting travellers from Uganda to five US airports to screen them for the Ebola virus, and is now monitoring them for 21 days to see whether symptoms develop. Neighbouring countries like Kenya and Tanzania are on high alert.
