About 100 Nigerian medical workers are expected to arrive in Sierra Leone to help with the response to the outbreak of the deadly Ebola virus, according to a BBC report.
The workers, who include doctors, scientists and hygienists, have been trained by the medical aid agency, MSF.
It came a day after residents in the Guinean capital, Conakry, protested about the construction of an Ebola treatment clinic in their district.
The Ebola outbreak has killed more than 6,000 people in West Africa this year.
The Nigerian medical workers are the first part of a contingent of about 250 specialists the West African country is deploying to the three countries worst hit by Ebola – Sierra Leone, Liberia and Guinea.
The workers are expected to stay for between three and six months, Nigerian officials say.
The BBC international development correspondent, Mark Doyle, says it is a reminder that although richer countries and the big aid agencies have been giving crucial help, Africans are very much part of the fight against Ebola too.
The Nigerian commitment is part of an African Union promise to send 1,000 medical workers to Ebola-hit areas by the end of this year.
