People travelling to India from Ebola-affected countries have been asked to carry a certificate stating that there is no evidence of the deadly virus in their body fluids.

The government advisory came after a person, who was cured of the disease in Liberia, had to be detained at the Delhi airport after his semen tested positive for the virus.

Health Minister JP Nadda told Lok Sabha on Friday that people, who have been treated for Ebola but do not have the certificate from the Health Ministry of the country concerned, have been advised not to travel to India for a period of 90 days from their discharge, PTI reported.

The Ministry of External Affairs had issued the advisory to the Indian embassies in Abidjan (Ivory Coast), Dakar (Senegal), Abuja (Nigeria), Accra (Ghana) and Niamey (Niger) on November 21.

Health Ministry officials said body fluids at times carry virus post-treatment.

"All passengers travelling from Ebola-affected countries or who have undergone treatment for Ebola have to produce a certificate from the Ministry of Health of the country that there is no evidence of virus in his/her body fluids," Nadda said, quoting the advisory.

"Passengers who do not posses the certificate are advised not to travel to India for a period of 90 days from the day he/she is discharged from the treatment facility," the minister added.
