The Liberian President, Ellen Johnson-Sirleaf, has expressed regret over the importation of the deadly Ebola virus by her national, late Patrick Sawyerr, to Nigeria.

Johnson-Sirleaf described as unfortunate the embarrassment and health challenges the incident had caused the government and people of Nigeria.

The minister of state for Foreign Affairs, Nurudeen Mohammed, who hinted of Johnson-Sirleaf’s concern, said she was worried over the spread of the disease in the country.

According to the minister, Johnson-Sirleaf had told the Nigerian government that Sawyer was placed on surveillance when he sneaked out of Liberia through ASky Airline into Nigeria.

Two deaths have so far been recorded from the Ebola virus in the country, while there are currently nine confirmed cases of infection.
