Between 24 and 27 July 2014, a total of 122 new cases of Ebola virus disease (EVD; laboratory-confirmed, probable, and suspect cases) as well as 57 deaths were reported from Guinea, Liberia, Nigeria, and Sierra Leone. The Ebola epidemic trend in Guinea, Liberia, and Sierra Leone remains precarious with ongoing community and health-facility transmissions of infection. The surge in the number of new EVD cases calls for concentrated efforts by all to address the identified problems, such as health facility transmission and effective contact tracing.
On 29 July 2014, the National IHR Focal Point for Nigeria confirmed that the probable EVD case notified to WHO on 27 July 2014 was symptomatic at the time of arrival in Nigeria and that 59 contacts (15 from among the airport staff and 44 from the hospital) have been identified so far. The report also confirms that the patient travelled by air and arrived in Lagos, Nigeria, on 20 July via Lomé, Togo, and Accra, Ghana.
The sample from this case is yet to be sent to the WHO Collaborating Centre at the Institute Pasteur in Dakar, Senegal, due to refusal by courier companies to transport this sample. Though only one probable case has been detected so far in Nigeria, Ebola virus infection in this country represents a significant development in the course of this outbreak.
