The UN health body said the arrival of the virus in Port Harcourt, which is 435 kilometres east of Lagos, showed "multiple high-risk opportunities for transmission of the virus to others".
The haemorrhagic fever, which has hit five countries in West Africa and caused nearly 2,000 deaths this year, first arrived in Nigeria when a Liberian finance ministry official died in Lagos on July 25.
He was taken from the city's airport to a private hospital by two officials from the West African regional bloc ECOWAS.
The ECOWAS official recovered but the WHO said Enemuo continued to treat patients at his private clinic and operated on at least two people, despite showing symptoms from August 11 of Ebola, of which he later died.
"On 13 August, his symptoms worsened; he stayed at home and was hospitalized on 16 August," the WHO said in an emailed statement.
"Once hospitalized, he again had numerous contacts with the community, as members of his church visited to perform a healing ritual said to involve the laying on of hands."
Over the six days he spent in hospital "the majority" of healthcare staff treated him while two doctors performed an abdominal scan at an ultrasound clinic the day before his death, the statement added.
"Given these multiple high-risk exposure opportunities, the outbreak of Ebola virus disease in Port Harcourt has the potential to grow larger and spread faster than the one in Lagos," it added.
