Adewole, who made this known at the Emergency National Council of Health in Abuja on Monday, said that in 2018 alone, Nigeria recorded 77 cases of Lassa fever.
According to him, the cases were in Bauchi, Plateau, Taraba, Nasarawa, Benue, Kogi, Ebonyi, Rivers, Imo, Anambra, Edo, Delta, Ondo, Osun and Lagos states.
The minister said 10 healthcare workers were affected in four states; seven in Ebonyi with one health worker from Nasarawa , Kogi and Benue states.
Adewole said of the 31 deaths from Lassa fever outbreak, four health workers died as a result of the disease; three deaths were recorded in Ebonyi and one in Kogi.
The minister, therefore, said the meeting was summoned to discuss the state of public health challenges in Nigeria with focus on some of the challenges that bedeviled the nation in the past few weeks.
Adewole added that Lassa fever has been a current outbreak in the country, stressing that Nigeria has battled with series of outbreaks in the past few months.
According to the minister, Nigeria has dealt with Ebola in 2014; the country reacted strongly and the response was acknowledged by the international community.
The minister said that Nigeria had also dealt with the resurgence of polio, adding that the issuance of recertification will be tougher than it was before.
“The international community will not come to Nigeria’s rescue or certify the country polio free until everyone is sure that Nigeria is polio free, and that is another health challenge,’’ Adewole said.
The minister said the country had dealt with measles and persistent cases of measles across the country despite the available vaccines, adding that government has already commenced nationwide campaign against measles.
He lamented that many states were yet to pay counterpart fund for the measles campaign.
The minister said first confirmed case of yellow fever happened in 2017, 17 years after the last case in the country.
“We have also commenced the nationwide immunisation against yellow fever that will take about seven years to complete due to non-availability of vaccines and large number of people to vaccinate. We have already taken delivery of 25 million doses of vaccines; with these we should be able to go far but not far enough. We are already talking to stakeholders and international partners to shorten the campaign to five years,’’ he said.
Adewole added that Lassa fever has been persistent in the country for over the past 30 years and therefore, appealed to the Nigeria Institute of Medical Research (NIMR) and other research institutes to look into the changing dynamics of Lassa fever.
“Lassa fever use to occur only during dry season but now we are contending with an all year transmission of Lassa fever. NIMR director-general, other research institutes will need to find out whether we are dealing with a new strain of Lassa fever virus in the country,” Adewole said.
He also urged state governments and other key stakeholders to work closely with Nigeria Centre of Disease Control to address outbreak of diseases.
