Early this month, health officials in the Democratic Republic of the Congo reported that an unknown, flu-like illness had killed dozens in the country within a few months. The World Health Organization (WHO) investigated, alongside local authorities.
Finally, on Tuesday (Dec. 17), the cause of the sicknesses was announced: severe malaria potentially complicated by malnutrition. Reuters covered the news, citing a statement from the Congo's health ministry that read, "The mystery has finally been solved." At the time, the case count was 592, with the earliest cases occurring in October.
