>> Nigeria Centre for Disease Control
>> The Viral Haemorrhagic Fevers Preparedness and Response Plan has been developed to ensure the clarity of activities required for prevention, rapid detection, investigation, verification, and response to VHF cases and outbreaks. The implementation of this plan will minimise associated health consequences and the negative socio-economic impact of VHFs. The plan has been developed to be applied across the Federal, State and Local Government level covering several areas including surveillance and epidemiology, laboratory diagnosis, case management, risk communication etc. It covers the period before outbreaks and during outbreaks.
>>
>> In the reporting week ending on the 30th of July, 2017:
>>
>> o There were 357 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 as Nigeria has assiduously reinvigorated its efforts at eradicating Polio.
>>
>> o Two suspected cases of Cholera were reported from Ilorin East LGA in Kwara State with no laboratory confirmed case and no recorded deaths.
>>
>> o There were 17 suspected cases of Cerebrospinal Meningitis (CSM) reported from ten LGAs in eight States. Of these, none was laboratory confirmed and no death was recorded. Ongoing surveillance for CSM has been intensified in the States.
>>
>> o There were 449 suspected cases of Measles reported from 33 States. None was laboratory confirmed and one death was recorded.
>>
>> In the reporting week, Lagos State failed to send in any report. Timeliness of reporting increases from 82% to 83% in the previous and current weeks (Week 29 and 30) while completeness also remains at 100%. It is very important for all States to ensure timely and complete reporting at all times, especially during an outbreak.
