NEW DELHI -- India quarantined a person Tuesday who had been infected with the Ebola virus in Liberia but then determined by Liberian officials to be free of the disease.

The patient, a 26-year-old Indian national who returned from Liberia on Nov. 10, was isolated at a special facility at the New Delhi airport after his semen sample tested positive for the virus, a report from the Press Trust of India (PTI), published in The Indian Express, said.

The man was carrying a certificate, from the Liberian government, clearing him of the Ebola virus, and stating that “he has successfully undergone care and treatment related to Ebola and after post-treatment assessment has been declared free of any clinical signs and symptoms and confirmed negative by laboratory analysis," PTI reported, citing an official statement.

News agency ANI quoted health minister J.P.Nadda as saying that the person had been kept in isolation and was "being closely monitored."

"We are cautious but there is no need to panic. Situation is under control," Nadda said, ANI reported.
According to the Centers for Disease Control and Prevention, a person who survives Ebola cannot spread the virus, but because the virus can be found in semen for up to 3 months, abstinence is recommended for this period.
