WHO’s office in Guinea says more than 1,000 contacts have been identified and placed under medical observation. Nearly 800 have been vaccinated over the past week, including 182 who are considered to be high-risk contacts.

The VSV-EBOV vaccine currently being administered was found to be highly effective in preventing Ebola infection in a large trial conducted by Guinea’s Ministry of Health, WHO and partner agencies last year. It has since been used in Sierra Leone to contain a recent flare-up there, and now, once again, in Guinea.

The “ring vaccination” strategy involves vaccinating anyone who has come into contact with a person infected with Ebola, as well as contacts of theirs.

In this latest flare-up, there have been 8 cases of Ebola and 7 deaths since late February. The most recent case, an 11-year old girl, is being treated at an Ebola care facility in Nzérékoré and as of today, is reported to be in a stable condition. Six of the deceased are from three generations of the same extended family in the village of Koropara Centre.
