On 7 June 2017, the Nigeria Federal Ministry of Health notified WHO of an outbreak of cholera in Kwara State in the western part of the country. The initial cases of acute watery diarrhoea (AWD) started insidiously during the last week of April 2017. Seven stool samples obtained from the initial cases and analysed at the University of Ilorin Teaching Hospital (UITH) laboratory isolated Vibrio cholerae O1 as the causative agent. The number of cases and deaths subsequently increased from the first week of May 2017. As of 14 June 2017, a total of 1,178 suspected cases and nine deaths (case fatality rate 0.8%) have been reported. Four local government areas have been affected, including Ilorin West (508 cases), Ilorin East (303 cases), Ilorin South (96 cases), and Moro (37 cases). (WHO, 23 Jun 2017)

The Borno State Ministry of Health in northeastern Nigeria reported suspected cholera in Muna Garage, a camp hosting about 20,000 internally displaced persons on the outskirts of the state capital Maiduguri. A total of 152 cases of suspected cholera, including 11 deaths, as of 31 August 2017, have been reported. (OCHA, 1 Sep 2017)

Over 530 suspected cases had been registered as of 5 September 2017, including 23 deaths (4.3 per cent fatality rate), mainly in Muna Garage

A Cholera Response and Prevention Plan, seeking US$9,9 million, has been developed to address the immediate needs of 3.7 million people that could be affected by the outbreak. (OCHA, 18 Sep 2017)

There is an ongoing outbreak since the beginning of 2017. Between 1 January and 31 December 2017, a cumulative total of 4 221 suspected cholera cases and 107 deaths (CFR 2.5%), including 60 laboratory-confirmed were reported from 87 LGAs in 20 States. Between weeks 1 and 9 of 2018, there have been 210 suspected cases including two laboratory-confirmed and 16 deaths (CFR 7.6%) from 28 LGAs in 9 States. (WHO, 30 Mar 2018)

North-east Nigeria is experiencing recurrent cholera outbreaks, with three states: Adamawa, Borno and Yobe currently having active transmission... Since February 2018, the three states in north-east Nigeria have reported a total of 1 664 suspected cholera cases and 31 deaths (case fatality rate 1.9%), as of 27 May 2018. (WHO, 28 May 2018)

With more than 14 days since the last reported case of cholera, Yobe State Ministry of Health has declared that the outbreak is over on 12 June 2018. (WHO, 12 June 2018)

The outbreak of cholera in Nigeria has remained persistent since the beginning of 2018. In epi-week 28 (week ending 15 July 2018), 367 new suspected cases with four deaths (case fatality ratio 1.1%) were reported from six states – Adamawa (42), Bauchi (56), Katsina (68), Niger (14), Plateau (11), and Zamfara (176)...As of 18 July 2018, a total of 16 892 suspected cases with 201 deaths (case fatality ratio 1.2%) have been reported from 17 states (Adamawa, Anambra, Bauchi, Borno, FCT, Gombe, Jigawa, Ebonyi, Kaduna, Kano, Katsina, Kogi, Nasarawa, Niger, Plateau, Yobe, and Zamfara) since the beginning of 2018...With no new cases reported in the last four weeks in Anambra, Nasarawa, Borno, and Yobe States the outbreak is considered to be under control in these states. The decrease in the number of cases has also been reported from Adamawa State, which has been one of the epi-centres of this outbreak. This is contributing to the overall declining trend across the country except in Zamfara and Katsina States where the number of cases reported is still high. (WHO, 27 Jul 2018)

The Borno State Ministry of Health in northeast Nigeria has reported 380 cases of suspected cholera in eight local government areas (LGAS) in the state, including 14 deaths, as of 5 September 2018.

(OCHA, 6 Sep 2018)

A total of 889 cases of suspected cholera have been recorded in eight local government areas (LGAs), including 19 deaths, as of 10 September 2018. This represents a fatality rate of 2.1 per cent...The number of cases has increased by 30 percent between 7 September and 10 September 2018, including one additional death. Jere, Magumeri and Maiduguri Metropolitan Council (MMC) have seen the largest spike in case numbers, largely due to the poor water, sanitation and hygiene conditions in these areas that are also congested. (OCHA, 11 Sep 2018)

In week 36 (week ending 9 September 2018), 1 306 suspected cases including 24 deaths (CFR: 1.8%) were reported from five states: Zamfara (588 cases with 12 deaths), Katsina (377 cases with 12 deaths), Borno (280 cases), Adamawa (55 cases), and Kano (6 cases).
