Ebola outbreak on track to be deadliest ever, WHO chief says

The current Ebola outbreak, declared on 15 May, has resulted in over 2,000 deaths and at least 4,300 reported cases, with the World Health Organization (WHO) warning that it is on track to become the deadliest ever. According to Tedros Adhanom Ghebreyesus, the WHO chief, the 2026 outbreak will "eclipse" the 2014-2016 occurrence, which killed at least 11,000 people, if it continues at its current pace. The outbreak is caused by the rare Bundibugyo species of Ebola, and health officials believe it began spreading at least three months before the official declaration in May, with the virus initially being misdiagnosed as malaria or typhoid. The key figure in the response to the outbreak is Dr Mohamed Janabi, the WHO Africa director, who has emphasized the challenges in controlling the spread of the disease, particularly due to ongoing regional instability near the location of the outbreak in the east of the Democratic Republic of Congo.

The most significant consequence of the outbreak is the lack of approved vaccines or recognized therapeutic drugs to treat the Bundibugyo species of Ebola, which has previously caused only two known outbreaks, in 2007 and 2012. As a result, health workers are facing significant challenges in controlling the spread of the disease, with Dr Janabi stating that they are only reaching about 30% of cases. The WHO has warned that reversing the spread of the disease within three months will require bringing transmission under control, but this does not mean ending the outbreak entirely. The organization is sponsoring a separate clinical trial in the Democratic Republic of Congo to see whether two existing antiviral therapies can improve survival rates. Additionally, the UK's medicines regulator has given permission for the first human trials of a vaccine for Bundibugyo to go ahead, with the jab being created by a team from the University of Oxford based on the same technology used in the Oxford-AstraZeneca Covid vaccine. Other groups are also developing different vaccines for Bundibugyo, although they have not yet entered clinical trials.

The implications of the outbreak are far-reaching, with the WHO and health workers facing significant challenges in controlling the spread of the disease. The fact that the virus is ahead of health workers, with Dr Janabi stating "we are chasing the virus, the virus is ahead of us," highlights the need for urgent action to bring transmission under control. The ongoing regional instability near the location of the outbreak has added to the challenges, and the lack of access to affected areas has limited the ability of health workers to reach all cases. As the outbreak continues to spread, it is likely to have a significant impact on the local population, with symptoms of the disease including fever, headache, and tiredness, which can develop suddenly and lead to organ failure if left untreated. The development of vaccines and therapeutic drugs is critical to controlling the outbreak, and the WHO's efforts to sponsor clinical trials and support the development of new treatments are essential to improving survival rates and ultimately bringing the outbreak under control.
