Nigeria has been placed on high alert following an ongoing Ebola Virus Disease outbreak in the Democratic Republic of Congo.
The Nigeria Centre for Disease Control and Prevention issued a fresh health advisory over the development.
The agency said it is strengthening preparedness measures to protect Nigeria from any possible threat.
The NCDC said the move followed a dynamic risk assessment and consultations with health experts.
It also consulted the Federal Ministry of Health and Social Welfare before issuing the advisory.
The agency said its response plans would continue to change based on the situation.
“These measures will continue to be reviewed in line with the evolving epidemiological situation and public health risk assessment.”
The NCDC advised travellers from countries with active or relevant Ebola transmission to complete the Health Declaration Form.
The form will support enhanced screening and follow-up for travellers arriving in Nigeria.
However, passengers from other countries are currently not required to complete the form.
The agency also urged Nigerians to remain alert for symptoms linked to Ebola Virus Disease.
People who develop concerning symptoms should seek medical care quickly.
They should also provide healthcare workers with relevant travel or exposure information.
Available data showed 7,672 confirmed cases and 3,699 related deaths as of September 20.
The figures were based on information recorded up to September 19. A total of 886 patients were receiving care in isolation facilities.

The DRC also recorded 58 new confirmed cases and 23 additional deaths.
The latest cases were reported across Ituri, North Kivu, Haut-Uélé and Tshopo.
Ituri recorded 38 cases, while North Kivu reported 14 cases.
Haut-Uélé recorded five cases, while Tshopo reported one case.
Meanwhile, 1,879 people who tested positive for Bundibugyo virus have recovered.
About 79.9 percent of identified contacts remain under follow-up in affected provinces.
The NCDC said it remains focused on surveillance, preparedness and response to health threats.
