Weekly Epidemiological Report

December 2018 Week 48


National Infection Prevention and Control Guideline Review

Posted: 24-12-2018 08:08:59 AM

As part of preparedness efforts for the Lassa fever season, the Nigeria Centre for Disease Control (NCDC) organised a three-day meeting to review the current infection prevention and control (IPC) guideline for the management of Viral Haemorrhagic Fevers (VHF). The review was held as part of preparedness efforts and to outline steps for institutionalizing IPC in health facilities in the country.

The objective of the meeting was to update the guideline with recommendations, Standard Operating Procedures (SOPs), checklists and assessment tools that will assist providers of VHF care and recipients of such care in making informed IPC decisions. Participants included IPC experts, Lassa fever case management experts, members from the academia and the national Lassa fever Technical Working Group. Significant areas for inclusion in the guideline were considered and these included the occupational health services in healthcare as well as principles of waste management in VHF treatment centres.

Break-out sessions were held where in-depth discussions and documentation of summaries of discussions, backed by scientific evidence were carried out. A major outcome from the meeting is a well revised IPC guideline which will serve as a reference documents for Nigeria in VHF management disseminated across all health facilities and designated VHF treatment centres in the country.


In the reporting week ending December 2, 2018:

o There were 145 new cases of Acute Flaccid Paralysis (AFP) reported. None was confirmed as polio. The last reported case of polio in Nigeria was in August 2016. Active case search for AFP is being intensified with the goal to eliminate polio in Nigeria.

o There were 62 suspected cases of Cholera reported from ten LGAs in six States (Bayelsa –1, Borno –9, Cross River –2, Kano –34, Katsina –1 and Yobe -15). Of these, none was laboratory confirmed and five deaths were recorded.

o There were 33 suspected cases of Lassa fever reported from 16 LGAs in 11 States (FCT –1, Gombe –2, Edo –3, Kaduna –3, Kano -1, Katsina – 1, Kogi -2, Nasarawa –1, Ondo –16, Osun–1 & Plateau -2). Thirteen were laboratory confirmed and two deaths were recorded.

o There were 16 suspected cases of Cerebrospinal Meningitis (CSM) reported from 13 LGAs in eight States (Bayelsa – 1, Cross River –3, Gombe –1, Katsina –2, Nassarawa –1, Ondo –2, Yobe -3 & Zamfara –3). Of these, none was laboratory confirmed and no death was recorded.

o There were 240 suspected cases of measles reported from 31 States. None was laboratory confirmed and one death was recorded.

In the reporting week, all States sent in their report. Timeliness of reporting remains 87% in both previous and current weeks (47 & 48) while completeness also remains 99% at the same period. It is very important for all States to ensure timely and complete reporting at all times, especially during an outbreak.
