What Is Bundibugyo Virus Disease?READ: Can Obeldesivir Prevent Ebola Symptoms After Exposure? Drug Trial Moves Forward As Death Toll Crosses 4,000Bundibugyo virus disease is a rare and deadly illness that has caused outbreaks in several African countries in the past.It is distinctly different from other known ebolaviruses like the Zaire ebolavirus or Sudan ebolavirus. The 2007 outbreak, where Bundibugyo was detected for the first time, resulted in over 100 cases and was officially declared over in early 2008.According to the US CDC, the Bundibugyo strain is spread by contact with the blood or body fluids of a person who is infected with or has died from BVD.It is also spread by contact with contaminated objects (such as clothing, bedding, needles, and medical equipment), or by contact with animals, such as bats and nonhuman primates, that are infected with BVD.Symptoms include fever, headache, muscle pain, weakness, diarrhea, vomiting, stomach pain, and unexplained bleeding or bruising (a late stage of illness).
