Report: 1,558 died of meningitis, cholera, others in 2018

...CSM hits Katsina, Yobe, Ebonyi, Ogun, 6 others

Fresh outbreak of Cerebrospinal Meningitis has killed nine and infected 72 persons in Katsina, Zamfara, Jigawa, Yobe, Bauchi, Ebonyi, Sokoto, Kano, Bayelsa and Ondo states.

The figure is part of the 1,558 Nigerians who lost their lives to CSM, yellow fever, cholera, monkey pox and other diseases in 2018.

 The figures, released yesterday by the Nigeria Centre for Disease Control in Abuja, showed that Katsina recorded most of the CSM-related cases and deaths followed by Zamfara, Jigawa, Ebonyi and Bauchi states

No deaths were, however, recorded in Sokoto, Kano, Yobe, Bayelsa and Ondo states.

 Also, the NCDC reported 15 new suspected monkey pox cases of which six confirmed cases were recorded in Rivers (one), Bayelsa (two), Delta (one), Cross Rivers (one) and Edo (one).

Similarly, the World Health Organisation’s regional reference laboratory and Institute Pasteur (IP) in Dakar, Senegal, has confirmed 13 new positive cases of Yellow Fever in Edo (nine), FCT Abuja (three) and Ekiti (one).

Latest figures on CSM outbreak from the NCDC showed as at epidemic (epi-week) 50, eight new suspected cases were reported from Katsina state.

According to the report,”from October 1, 2018 to December 18, 2018, a total of 72 suspected cases have been reported from 10 states. Four samples were positive for bacterial meningitis. Neisseria meningitides serogroup C (NMC) accounted for 100 per cent or four of the positive cases. So far, nine deaths with Case Fatality Ration (CFR) of 12.5 per cent have been recorded among all suspected cases.

 “As the dry season begins, we expect increase in the number of CSM cases in Nigeria. This is the first for the 2018/2019 season.

  “The National Technical Working Group for Cerebrospinal Meningitis has been preparing ahead of the 2018/2019 meningitis season. States in the meningitis belt were formally placed on alert on the 8th of November, 2018,” the NCDC stated.

Yellow fever

  On Yellow Fever outbreak, the NCDC noted that from the onset of the outbreak in September 2017 to date, 3,902 suspected cases have been reported from all 36 states and the FCT in Nigeria.

  According to the Centre, of the 3,295 samples collected and tested, 185 were presumptive positive in-country and were sent for confirmation to IP in Dakar and so far, 78 positive cases from Kwara, Kogi, Kano, Zamfara, Kebbi, Nasarawa, Niger, Katsina, Edo, Ekiti, Rivers, Anambra, FCT and Benue states have been confirmed.

  The Centre further noted that since the outbreak, 13 deaths in IP Dakar confirmed cases and 27 deaths in presumptive positive cases have been recorded and CFR among presumptive positive and IP Dakar confirmed cases were 14.6 per cent and 16.7 per cent respectively.

  “It said Yellow Fever preventive mass vaccination campaigns have been conducted in Borno, Kebbi, Niger, Plateau, Sokoto and the FCT between November 22, 2018 and December 2, 2018, bringing the total states covered by preventive mass vaccination campaign to 12.

Monkey pox

On Monkey pox, the NCDC said Nigeria continues to report sporadic cases of the disease since the beginning of 2018.

  It noted that 114 suspected, 45 confirmed, one probable cases and one death have been reported in 2018, and the 45 cases confirmed were recorded in Rivers, Bayelsa, Delta, Oyo, Cross River, Edo, Enugu, Imo, Lagos, Plateau, Abia, Anambra and Nasarawa states.


How Nigeria fared in 2018

Every year, Nigeria battles communicable diseases, some of which are on the national priority list for eradication.

PREMIUM TIMES analyses how Nigeria fared in 2018 in the surveillance, prevention and management of six diseases that caused the death of hundreds of people in the country.

1. Polio

Since the beginning of 2018, Nigeria has not recorded any active case of Wild Poliovirus (WPV) in the country.

Though there were reports of suspected cases of the disease, none was positive. The weekly epidemiological report from the NCDC revealed that 145 new cases of Acute Flaccid Paralysis (AFP) was reported. None was confirmed as WPV.

This is a good report for Nigeria which was on the verge of being declared polio-free but had a major setback in August 2016 when an active case of polio was reported in Borno state.

This led the government to intensify its effort in the eradication of the disease in the country. This is being done by intensifying polio vaccination campaigns.

The last reported case had been a major setback to the global campaign to eradicate polio.

Globally, Nigeria is one of only three countries in the world with ongoing Wild Polio Virus (WPV) transmission, alongside Afghanistan and Pakistan.

The epidemiological report for week 48 which ended December 2 shows that no new case of WPV was recorded.

Reports from NCDC showed that in the reporting week, 145 suspected cases of AFP were reported from 114 LGAs in 35 states.

In total, between week 1 and 48 (2018), 8,132 suspected cases of AFP were reported from 752 LGAs in 37 States and none was confirmed as WPV.

Although, no WPV was discovered in 2018, the World Health Organisation (WHO) announced the discovery of a Type-2 polio virus in Bauchi state.

The virus was discovered during the monthly collection of samples from different locations.

The latest strain of the virus was from isolated environmental samples from the Gwallaga area, as well as refuse dump sites and drainages.

The vaccine-derived poliovirus was linked to the one earlier discovered in Hadeja, Jigawa state. The new strain is as a result of non-compliance to immunisation schedules.

In Bauchi local council area, only 52 per cent of children are fully immunised, 29 per cent did not complete their routine, while 19 per cent have never been immunised.

FG cautions

The Minister of Health, Professor Isaac Adewole, had earlier in the year, said Nigeria will not be quick to get a polio-free certificate as the country needs to tread with caution.

This, he said, is necessary because of the hard to reach areas for vaccination in Borno state.

Adewole said there are still some areas in the insurgency-ravaged zone of Borno state and neighbouring countries of Niger and Chad which are yet to be effectively covered.


Since the beginning of the year, 124 persons have died from measles in Nigeria.

According to NCDC weekly epidemiological report for week, 48, 16,393 suspected measles cases with 1110 laboratory-confirmed and 124 deaths (CFR, 0.8 per cent) were reported from 36 states and FCT.

The suspected case was lower than 2017 where 21,162 suspected cases with 109 laboratory-confirmed.

The death record was however slightly higher in 2018 as 112 deaths (CFR, 0.53 per cent) from 36 states and FCT was recorded during the same period in 2017

NCDC said response measures in places affected include immunisation for all vaccine-preventable diseases in some selected/affected wards and LGAs during Supplementary Immunisation Activities (SIAs), as well as case management.

Measles is one of the vaccine preventable communicable diseases that Nigeria and the world is yet to successfully combat.

Even though a safe and cost effective vaccine is available, there were over 110,000 measles deaths globally, mostly among children under the age of five.

To curb deaths among children under five, the Nigerian government has been carrying out aggressive immunisation campaigns on polio and measles across the country.

Measles is a highly contagious infectious disease caused by the measles virus.

Unvaccinated young children are at highest risk of measles and its complications, including death. Unvaccinated pregnant women are also at risk. Any non-immune person (who has not been vaccinated or was vaccinated but did not develop immunity) can become infected.

Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C, cough, runny nose, and inflamed eyes.

 Cerebrospinal Meningitis

Nigeria is currently at the beginning of a new Cerebrospinal Meningitis season. The disease which is synonymous with the dry season starts in December and peaks around March and April before subsiding in June/July every year.

So far, between weeks 1 and 48 (2018), 4,448 suspected meningitis cases with 318 laboratory confirmed and 359 deaths (CFR, 8.1 per cent) from 299 LGAs (35 states).

This is far lower when compared with 9,918 suspected cases and 606 deaths (CFR, 6.1 per cent) from 326 LGAs in 34 states during the same period in 2017.

With the new meningitis season approaching, the epidemiological report in the reporting week, said 16 suspected Cerebrospinal Meningitis (CSM) cases were reported from 13 LGAs in eight states ( Bayelsa 1, Cross River –3, Gombe –1, Katsina –2, Nassarawa –1, Ondo –2, Yobe -3 and Zamfara –3) compared with 16 suspected cases and four deaths reported across eight LGAs in six states at the same period in 2017.

NCDC also said the timeliness/completeness of CSM case-reporting from states to the national level (2018 versus 2017) is picking up, though it is still on average.

“88.2 per cent of the 26 endemic states sent CSM reports in a timely manner while 98.2 per cent were complete in week 1-48, 2018 as against 76.4 per cent timeliness and 92.3 per cent completeness recorded within the same period in 2017,” it stated.

Surveillance and timely report of meningitis cases has remained a challenge in the country, though efforts are being made to combat the issue.

The last diagnosis and reporting of the disease led to the death of over 1,000 people during the meningitis outbreak in the 2016/2017 season.

This was further compounded by the lack of vaccine to immunise people against the disease.

So far, the government has been able to immunise many Nigerians in the meningitis-prone states.


Nigeria recorded 1,132 deaths this year from such outbreaks in 30 states across Nigeria as the disease claimed more lives in parts of the country.

The death figure this year is several times higher than the 84 recorded within the corresponding period in 2017, the NCDC disclosed in its epidemiological report.

Between weeks 1 and 48 (2018), 50,463 suspected cholera cases with 934 laboratory-confirmed and 1132 deaths from 245 LGAs in 30 states were reported compared with 3703 suspected cases and 84 deaths from 73 LGAs in19 states during the same period in 2017.

Eight states most hit in the current outbreaks are Adamawa, Borno, Katsina, Yobe, Zamfara, Bauchi Kano and Gombe.

The disease though vaccine preventable has become a yearly occurrence in Nigeria. Outbreak peaks during the rainy season and when there is flood. This is due to the fact that most house do open defecation, lack good  sanitation and access to potable water.

Worse hit this year were the Internally Displaced Persons (IDP camps). This led the federal government and international partners to conduct an emergency cholera immunisation for people living in the IDP camps and neighbouring states which witnessed the outbreaks.

NCDC had also set up a Cholera National Emergency Operations Centre (EOC) in the worse hit states. But  this has been de-escalated to a Technical Working Group following a decline in number of new cases reported from states in the last six week

 Lassa Fever

Nigeria was in news negatively this year as the Lassa Fever outbreak in the country reached a highest new peak ever in the history of the disease.

The death toll for lassa fever outbreak in 2018 as at December 2 was 146.

From January 1 to December 2, 2018, 3,229 suspected cases have been reported from 23 states.

Of these, 581 were confirmed positive, 17 probable and 2,631 negative (not a case).

Since the onset of the 2018 outbreak, there have been 146 deaths among confirmed cases and 17 among probable cases. Case Fatality Rate in confirmed cases is 25.1 per cent.

NCDC said the reason for the spike in the number this year is yet to be ascertained.

The Director General, NCDC, Chikwe Ihekweazu, said this could be due to increase surveillance and case tracing of contacts.

Although the Lassa fever outbreak for 2017/2018 was declared over by the Federal Ministry of Health in May, pocket of cases were still being reported.

In the reporting Week 48 (26 November – 2 December, 2018), 13 new confirmed cases were reported from Edo 2, Ondo 8, Gombe 1, Plateau 1 and Kano 1.

So far, 23 states have recorded at least one confirmed case across 92 LGAs (Edo, Ondo, Bauchi, Nasarawa, Ebonyi, Anambra, Benue, Kogi, Imo, Plateau, Lagos, Taraba, Delta, Osun, Rivers, FCT, Gombe, Ekiti, Kaduna, Abia, Adamawa, Enugu and Kano).

Eighteen states have exited the active phase of the outbreak while five – Edo, Ondo, Plateau, Gombe and Kano states remain active.

According to NCDC, the Lassa fever national multi-partner, multi-agency Technical Working Group (TWG) continues to coordinate response activities at all levels.

 Yellow fever

Since September 2017 when the first case of yellow fever was rediscovered in Kwara state, 55 deaths have been recorded.

Since the onset of the outbreak of the disease, 3,456 suspected yellow fever cases with 56 Laboratory confirmed and 55 deaths (CFR, 1.6 per cent) have been reported from 570 LGAs (36 states & FCT).

Yellow fever is one of the vaccine preventable diseases which is expected to be given to children during the routine immunisation.

The routine yellow fever vaccination was introduced to Nigeria’s expanded programme on immunisation, (EPI), in 2004.

Unfortunately, the first case was detected in a seven-year-old girl in September, 2017. She had no previous history of yellow fever vaccination. She also had no travel history outside her state two years before the illness.

So far, 58 cases have been confirmed by the WHO reference laboratory, Institute Pasteur (IP) Dakar from 14 states (Kwara, Kogi, Kano, Zamfara, Kebbi, Nasarawa, Niger, Katsina, Edo, Ekiti, Rivers, Anambra, FCT, and Benue states).

Nigeria has no laboratories to diagnose the ailment. This means sample of patients needs to be taken to Dakar, Senegal before confirmatory reports can be gotten.

In a reactionary approach, the federal government and international partners have conducted yellow fever reactive vaccination campaigns in the following states: Kebbi (7 LGAs), Niger (5 LGAs), Sokoto (1 LGA) and Katsina (1 LGA).

The campaigns have also been successfully completed in six States (Nasarawa, Cross River, Akwa-Ibom, Kogi, Kwara & Zamfara) and 57 political wards in 25 LGAs in Borno State.

The 2018 Preventive Mass Vaccination Campaign (PMVC) also held from November 22 and December 1 in Sokoto, Kebbi, Niger, FCT, Plateau and some LGAs in Borno State.

The target population is persons between nine months and 44 years (85 per cent of the total population).
