Man Recovering From Ebola Quarantined at Delhi Airport

New Delhi: India has quarantined a man who was cured of Ebola in Liberia but continued to show traces of the virus in samples of his semen after arriving in the country, the Health Ministry said on Tuesday.

The ministry said in a statement that the Indian national had been shown to be negative for Ebola in tests conforming to World Health Organisation (WHO) guidelines, but had been quarantined as a precautionary measure when he arrived at New Delhi airport on November 10. Later, tests of his semen detected traces of the virus.

"It is a known fact that, during convalescence from Ebola Virus Disease, persons continue to shed virus in bodily fluids for variable periods," the ministry said. "However, presence of virus in his semen samples may have the possibility of transmitting the disease through sexual route up to 90 days from time of clinical cure."

India has screened thousands of passengers travelling from Ebola-hit West Africa in recent weeks.

The Indian national carried with him documents from Liberia that stated he had been cured. He will be kept in quarantine until the virus is no longer present in his body, and will undergo tests over the next 10 days or so, a senior Health Ministry official said.

"It is not an Ebola case, he is an Ebola-treated patient who is negative in blood but whose body fluid is positive. He has no symptoms," the official said, declining to be named because of the sensitivity of the matter.

Peter Piot, a former WHO official who was one of the discoverers of the virus, has in the past expressed concerns about the disease spreading to India. There are nearly 45,000 Indian nationals living in West Africa.

The current outbreak of Ebola is the worst on record. It has killed at least 5,177 people, mostly in Sierra Leone, Liberia and Guinea, according to the latest figures from the WHO.
