SITUATION OVERVIEW
A total of 4 confirmed cases were reported from Freetown (2) and Port Loko (2) in the week to 19 July. A new EVD confirmed case has been reported in Tonkolili after 150 days with no cases as of 23 July.
The first case from Freetown is a health worker who tested positive for EVD after the onset of symptoms in a voluntary quarantine facility. The second case was found with advanced symptoms outside a com-munity health facility near the Magazine Wharf community, which reported 8 cases last week. However, the case is not a registered contact of any case from the Magazine Wharf chain of transmission. Investigations are underway to determine the source of infection and any contacts of the case. Contact tracing is complicated by the fact that the case has no fixed address and was symptomatic for an unknown period prior to identification.
Two cases were reported from the chiefdom of Marampa in Port Loko. Both are registered contacts associated with a transmission chain linked to an EVD-positive mother who died during childbirth in mid-June.
Three of the 4 cases reported from Sierra Leone in the week to 19 July were registered contacts. No cases were identified as a result of post-mortem testing of community deaths.
On 19 July, a total of 618 contacts were being monitored in 4 districts: Kambia, Port Loko, Western Area Rural, and Western Area Urban.
Laboratory indicators continue to reflect a heightened degree of vigi-lance, with 1502 new samples tested in the 6 days to 19 July.
