The U.S. Centers for Disease Control and Prevention (CDC) released an updated report on the ongoing efforts to contain the Ebola outbreak affecting West Africa on Tuesday.
The CDC said the World Health Organization (WHO) reports 17,908 cases of Ebola infection in Liberia, Sierra Leone and Guinea as of Dec. 7.
Transmission rates in these countries are the highest and the major points where the infection has spread.
Sierra Leone has the highest number of reported cases at 7,897 cases with Liberia at 7,719 cases. Guinea has reported 2,292 cases.
The total number of fatalities attributed to the Ebola hemorrhagic fever virus has reached 6,373.
The CDC reports that efforts in Mali to curb localized transmissions are ongoing, with eight cases reported with six deaths. In October, transmission was successfully interrupted in Nigeria and prevented in Senegal.
Between Nov. 9 and Dec. 6 there were 4,281 new cases reported. Between Oct. 19 and Nov. 8, there were 2,705 new cases.
The distribution of cases encompasses many districts within all three countries.
For both spans of time, the largest concentration of infection was in the Monrovia region of Liberia. The CDC said there have been cumulative incidents of more than 300 per 100,000 individuals in Monrovia.
