of the
Ebola virus disease epidemic.
His mother, sister, and grandmother then became ill with similar symptoms and also died. People infected by those initial cases spread the disease to other villages.
Although Ebola represents a major public health issue in sub-Saharan Africa, no cases had ever been reported in West Africa and the early cases were diagnosed as other diseases more common to the area. Thus, the disease had several months to spread before it was recognized as Ebola.
Index Case
The index case in Nigeria was a Liberian-American,
Patrick Sawyer, who flew from Liberia to Nigeria's most populous city of
Lagos

on 20 July 2014. Sawyer became violently ill upon arriving at the airport and died five days later. In response, the Nigerian government observed all of Sawyer's contacts for signs of infection and increased surveillance at all entry points to the country.
Sawyer was believed to have suspected he was infected with Ebola because he cared for his sister who died of the disease on July 8, he was hospitalised in Monrovia for fever and Ebola symptoms on July 17 before discharging himself (against professional medical advice) to fly to Lagos, where he lied to the staff of
First Consultants Medical Centre that he had not had any exposure to anyone that had contracted Ebola.
Subsequent Transmission
On 6 August 2014, the Nigerian health minister told reporters, "Yesterday the first known Nigerian to die of Ebola was recorded. This was one of the nurses that attended to the Liberian. The other five newly confirmed cases are being treated at an isolation ward."
The nurse was Obi Justina Ejelonu.
The doctor who treated Sawyer,
Ameyo Adadevoh

, subsequently also died of Ebola.
Others that died included Mrs Ukoh (a Ward Maid at First Consultants Medical Center), Jato Asihu Abdulqudir (an acquaintance of Sawyer, who was on the plane with him and carried his bag when he was ill), a private hospital doctor in Port Harcourt who was treating Jato and an elderly patient at the hospital that treated the private hospital doctor for Ebola.
On 22 September 2014, the Nigeria health ministry announced, "As of today, there is no case of Ebola in Nigeria. All listed contacts who were under surveillance have been followed up for 21 days." According to the WHO, 20 cases and 8 deaths had been confirmed, including the imported case, who also died. Four of the dead were health care workers who had cared for Sawyer. In all, 529 contacts had been followed and of that date they had all completed a 21-day mandatory period of surveillance.
Outbreak successfully contained

(ECDC) acknowledged Nigeria's positive role in controlling the effort to contain the Ebola outbreak. "We wish to thank the Federal Ministry of Health, Abuja, Nigeria, and the staff of the Ebola Emergency Centre who coordinated the management of cases, containment of outbreaks and treatment protocols in Nigeria." Nigeria's quick responses, including intense and rapid contact tracing, surveillance of potential contacts, and isolation of all contacts were of particular importance in controlling and limiting the outbreak, according to the ECDC. Complimenting Nigeria's successful efforts to control the outbreak, "the usually measured WHO declared the feat 'a piece of world-class epidemiological detective work'."
The WHO's representative in Nigeria officially declared Nigeria to be Ebola free on 20 October after no new active cases were reported in the follow up contacts, stating it was a "spectacular success story".

Background: Healthcare in Nigeria
Health care delivery in Nigeria is a concurrent responsibility of the three tiers of
government

in the country, and the private sector. Nigeria has been reorganizing its health system since the
Bamako Initiative of 1987, which formally promoted community-based methods of increasing accessibility of drugs and health care services to the population, in part by implementing user fees. The new strategy dramatically increased accessibility through community-based healthcare reform, resulting in more efficient and equitable provision of services.
A comprehensive approach strategy was extended to all areas of health care, with subsequent improvement in the health care indicators and improvement in health care efficiency and cost.
The Nigerian health care system is continuously faced with a shortage of doctors and nurses known as '
brain drain', because of
emigration by skilled Nigerian doctors and nurses to North America and Europe. In 1995, it was estimated that 21,000 Nigerian doctors were practising in the United States alone, which was about the same as the number of doctors working in the Nigerian public service. Retaining these expensively trained professionals has been identified as one of the goals of the government.
Despite this, in the 2014 Ebola outbreak, Nigeria was the first country to effectively contain and eliminate the Ebola threat that was ravaging three other countries in the West African region. The Nigerian unique method of contact tracing became an effective method later used by other countries, such as the United States, when Ebola threats were discovered.
In popular culture
The 2016 Nigerian drama thriller film ''
93 Days'' tells the story of the treatment of Patrick Sawyer by Adadevoh and other medical staff, and the successful containment of the outbreak.
