The female: male ratio among confirmed cases is 1.2 : 1.

Contact tracing activities continue in all affected areas. A total of 230 contacts are currently under medical observation and 53 have completed their 21 days of follow-up. Seven contacts who developed symptoms continue in isolation as a precautionary measure.

Efforts to increase public health awareness continue. The Ministry of Foreign Affairs of Guinea convened a meeting with a number of diplomatic missions on April 18 where the Minister of Health, supported by the World Health Organization (WHO) Representative, WHO Country Office for Guinea, and WHO EVD Response Coordinator, briefed the meeting. WHO and the Global Outbreak Alert and Response Network are in the process of deploying additional experts to support activities in case management, infection prevention and control, contact tracing, social mobilization and psychosocial support.

Numbers of cases and contacts remain subject to change due to consolidation of cases, contact and laboratory data, enhanced surveillance and contact tracing activities and the continuing laboratory investigations.
