(CNN) There have been 18 more cases of illness and five more deaths reported in just two days in the Ebola outbreak in the Democratic Republic of Congo, according to the Ministry of Health. Since the outbreak began, the total number of probable cases is now 471, including 273 deaths, the ministry reported Thursday.
Public health authorities are investigating an additional 106 suspected cases, the ministry indicated.
This is the 10th outbreak since 1976 in Congo, where the virus is endemic, and the second this year. It is also now the second-deadliest Ebola outbreak in history, topped only by one in West Africa in 2014, when the disease killed more than 11,000 people.
