The three Nigerians, who are aged 4, 37 and 79, were kept in isolation at the Delhi hospital and were screened for the virus. The blood samples of the three patients had been sent to the National Centre for Disease Control (NCDC), Delhi, for testing. The results that came back from the NCDC are said to be inconclusive. However, the 4-year-old and the 37-year-old have been released from the hospital as the doctors do not believe that they are carrying the deadly virus.
The 79-year-old Nigerian's condition is believed to be the worst of the lot, and his blood samples have been sent to the National Institute of Virology (NIV), Pune, for further testing.
"His blood samples have been sent to NIV for RT-PCR (real-time polymerase chain reaction)," said Dr HK Kar, the Medical Superintendent of the RML Hospital, to NDTV. "He was admitted to the hospital from the airport yesterday along with two other Nigerian nationals, who were discharged today after they tested negative (for the virus)."
