The Nigeria Centre for Disease Control, NCDC, on Friday confirmed the death of seven persons, in an outbreak of yellow fever in Bauchi State, with four victims on treatment.
NCDC is a parastatal of the Ministry of Health .
Among those who reportedly died were students of Waka College of Education in Biu Local Government Area, Borno State.
While three of the confirmed cases were said to be residents of Alkaleri Local Government Area, the fourth victim was a tourist who was visiting Kano State and Yankari Games Reserve in the same LGA in Bauchi State.
The Director-General of NCDC, Dr. Chikwe Ihekweazu, who made the disclosure in a statement in Abuja, said the agency was first notified on August 29, when it received the report of a confirmed case of Yellow Fever in Kano State from a laboratory in the Yellow Fever laboratory network.
He said, “Subsequent investigations led by the Kano State Epidemiology Team established that this confirmed case of yellow fever was from a patient who visited the Yankari Game Reserve in Bauchi, in August 2019 with his father. Unfortunately, the father died with similar symptoms before a sample could be collected and tested.
“Subsequently, on September 3 2019, the Borno State Epidemiology Team reported deaths among students of Waka College of Education in Biu LGA Borno State. These students visited the Yankari Game Resort in August 2019.
“Of the 95 students that visited the resort, eight of them developed symptoms and six had died as at the time of the report. The others are in a stable condition. Samples from these cases are being tested.
“Intensification of surveillance activities has led to the identification of three more confirmed cases who are all resident in Alkaleri LGA of Bauchi state.
“Altogether, we can confirm four cases of yellow fever in people that either live or have visited Bauchi in the last one month.
“Since it was notified, the NCDC has collaborated with the State epidemiologists of the affected States and the World Health Organization country office to investigate these events.
“We have also deployed a rapid response team to support Bauchi State to carry out further in-depth investigations, including case finding, risk communications, and support the management of cases.
“Samples of the other suspected cases from Bauchi and Borno states are currently being transported to the NCDC National Reference Laboratory in Abuja for further testing.
“Today (Friday), we activated our Emergency Operations Centre to coordinate the response to this outbreak.”
The NCDC said Yellow Fever virus is spread through bites of an infected mosquito with no human-to-human transmission of the virus.
The organization said, “Yellow fever is a completely vaccine-preventable disease and a single shot of the yellow fever vaccine protects for a lifetime. The yellow fever vaccine is available for free in all primary healthcare centres in Nigeria as part of the routine childhood immunisation schedule. We encourage every family to ensure that children receive all their childhood vaccines.
“In addition to the vaccine, the public is advised to keep their environments clean and free of stagnant water to discourage the breeding of mosquitoes and ensure the consistent use of insecticide treated mosquito nets, screens on windows and doors to prevent access for mosquitoes.
“Especially, hikers, park visitors and people engaged with activities in the wild are encouraged to be vaccinated against yellow fever. It is important to avoid self-medication- visit a health facility immediately if you feel ill.
“A multi-agency Yellow Fever technical working group coordinated by NCDC, has been leading the preparedness and response to yellow fever in Nigeria.
The National Primary Health Care Development Agency is leading efforts to provide an additional opportunity of vaccination through preventive vaccination campaigns across the country.
