The Democratic Republic of Congo (DRC) continues to experience an outbreak of Ebola viral disease (EVD). Despite the moderate risk of spread to countries like Nigeria, the Nigeria Centre for Disease Control (NCDC) continues to work with sister agencies and partners to ensure Nigeria is prepared to prevent, quickly detect and respond to an Ebola outbreak.
On the 17th of June 2019, a passenger traveling through the Lagos airport fell ill and was immediately suspected for Ebola. While this turned out to be false, it provided an opportunity for NCDC, Port Health Services and other partners to test the country’s level of preparedness.
The passenger who came in with a fever was immediately detected and isolated, and managed under strict infection prevention and control measures. In addition, NCDC, PHS, World Health Organisation (WHO) and partners carried out a risk assessment immediately to define response activities as needed. The Permanent Secretary of Health quickly issued a press release and led a high-level delegation of staff from the Federal Ministry of Health and NCDC, to Lagos state.
The ‘Ebola scare’ in June 2019, provided an opportunity for a simulation that highlighted gaps and strengths in the country’s level of preparedness. NCDC’s capacity has improved, with ability to detect the virus in the National Reference Laboratory, trained human resource for outbreak response and highly pathogenic infection management, an Incident Coordination Centre for response coordination, risk communications and other aspects. NCDC remains committed to working with our parent Ministry and partners, to ensure Nigeria is prepared in the event of an outbreak.
