Ebola Update (17 July 2015)July 17, 2015 in Ebola
In the seven days leading up to 12 July, there were thirty confirmed cases of Ebola Virus Disease (EVD) reported in Guinea, Liberia and Sierra Leone. While the total number of confirmed cases is the same as during the previous weeks, officials have noted that there has been a shift in the foci of transmission. During this reporting period, Guinea recorded 13 cases; Liberia 3; and Sierra Leone 14.
For the first time in several months, most of the cases that were reported during this period occurred in the capitals of Guinea (Conakry) and Sierra Leone (Freetown).
There have been a total of 27,642 confirmed, probable and suspected cases of EVD in Guinea, Liberia and Sierra Leone and 11,261 reported deaths. As of 12 July, there are 3,552 contacts being monitored across 6 prefectures in Guinea; 2 counties in Liberia and 3 districts in Sierra Leone.
Guinea recorded 13 confirmed cases of EVD in 3 prefectures: Conakry, Forecariah and Fria. For the first time in several months, the majority of the cases reporting during this week, 9, occurred in the capital, with seven of the 9 cases being reported in the Ratoma commune (administrative district). The remaining two were reported from the neighbouring commune of Matam. Officials have indicated that all of the cases are either registered contacts or have an epidemiological link to a known chain of transmission.
The small western prefecture of Fria reported a confirmed case this week for the first time in over forty days. Officials have indicated that the case is a contact of a previous case in the northern prefecture of Boke.
The northern prefecture of Boke, which had been a focus of transmission for several weeks, has not reported a case in eleven consecutive days, however officials have warned that cases may still arise as 125 contacts associated with previous cases are still being monitored.
During the reporting period, there were three new cases recorded in Liberia, bringing the total number of cases sine 29 June to six.
Officials have indicated that all of the three confirmed cases reported in the week leading up to 12 July were registered contacts associated with the same chain of transmission as the three cases reported in the previous week.
During this reporting period, there were 14 confirmed cases recorded in three districts: Freetown, Kambia and Port Loko. This is the highest total since the second week in June.
For the first time in several months, the majority of cases were reported in the capital city, Freetown. According to officials, eight of the 10 cases reported from the capital were registered contacts residing in quarantined homes in the Magazine Wharf area of the city, which has been a focus of transmission for several weeks. The two remaining cases both have an epidemiological link to the Magazine Wharf chain of transmission however they were identified after post-mortem testing and therefore represent a high risk of further transmission.
There were two cases reported in Kambia, in the Samu chiefdom on the northern border with Forecariah, Guinea. Officials have indicated that both cases were known contacts of a previous case. The remaining case was reported from a quarantined home in Tonko Limba chiefdom, and was also a registered contact of a previous case.
There was one case reported in Port Loko, in the chiefdom of Marampa. The source of infection is currently under investigation.
