The scientists are from the Centers for Disease Control and Prevention, and they have embarked on this watery journey to solve a decades-old mystery about a rare and fatal disease: monkeypox.
A cousin to the deadly smallpox virus, the monkeypox virus initially infects people through contact with wild animals and can then spread from person to person. The disease produces fever and a rash that often turns into painful lesions that can feel like cigarette burns. It kills up to 1 in 10 of its victims, similar to pneumonic plague, and is particularly dangerous in children. Monkeypox is on the U.S. government list of pathogens such as anthrax and Ebola with the greatest potential to threaten human health. There is no cure.
Over the past year, reports of monkeypox have flared alarmingly across Africa, one of several animal-borne diseases that have raised anxiety around the globe. The Congolese government invited CDC researchers here to track the disease and train local scientists. Understanding the virus and how it spreads during an outbreak is key to stopping it and protecting people from the deadly disease.
