The authorities in Nigeria are afraid that the country is at high risk of importation of the Ebola virus following the outbreak of the disease in Uganda.
This is despite the West African not sharing a common border with Uganda.
However, the Nigerian Centre for Disease Control says the high level of risk to the country is due to the large volume of air travel between Nigeria and Uganda.
Moreover, it attributes this to the mixing of passengers, especially at the regional travel hubs of Nairobi, Addis Ababa and Kigali airports.
To this effect, health authorities say they are on alert, with a number of measures put in place to prevent and mitigate the impact of a potential Ebola outbreak in Nigeria.
These measures include increased surveillance and screening of passengers at airports.
