Russia has announced the development of a new vaccine for the recent strain of Ebola virus associated with the outbreak in the Democratic Republic of Congo (DRC). The vaccine, revealed by Health Minister Mikhail Murashko, is said to potentially safeguard against the rare Bundibugyo strain also connected to the DRC outbreak.
The World Health Organization (WHO) disclosed on May 25 that the Ebola outbreak in the DRC has led to 220 suspected deaths, with 101 confirmed cases and 10 confirmed deaths reported. WHO Director-General Tedros Adhanom Ghebreyesus emphasized that the actual scale of the outbreak is likely much larger, with over 900 suspected cases and 220 suspected deaths.
The outbreak, which WHO declared a public health emergency of international concern on May 17, has extended to Uganda, recording five confirmed cases and one death. DR Congo Health Minister Roger Kamba stated that while the Ebola outbreak is still in its early stages, the number of infections and deaths is on the rise.
Health authorities have identified approximately 1,000 suspected cases in affected regions, with 101 testing positive for the Bundibugyo strain of Ebola. Although this strain is considered less lethal than the Zaire strain, it remains perilous if the number of infections continues to increase. Currently, there is no approved vaccine or specific treatment for Bundibugyo Ebola.
Ebola is a severe and often fatal illness affecting humans and other primates, transmitted through contact with infected animals and then spreading among humans through direct contact with bodily fluids. The average fatality rate for Ebola cases is around 50%, with rates in past outbreaks ranging from 25% to 90%.
The first Ebola outbreaks were observed in remote Central African villages near rainforests, with the 2014–2016 West Africa outbreak being the largest and most complex since the virus’s discovery in 1976. This outbreak, originating in Guinea and spreading to Sierra Leone and Liberia, surpassed all previous outbreaks in terms of cases and deaths.
