THRISSUR: A nine-year-old girl from Nigeria has been admitted to the special Ebola quarantine unit at the Ernakulam General Hospital after she was found to be having cold, fever and breathlessness when she arrived at the Cochin International Airport on Monday morning.Health officials at the airport said that the quarantine measures were taken since Nigeria, along with neighbouring countries like Liberia, had earlier been declared as an Ebola-affected country.This was the first case of a passenger arriving at the Cochin International Airport from an Ebola-hit country with signs of fever and cold, the common symptoms of the deadly disease, said an official.The girl and her father were accompanying her mother who had come here to undergo an orthopaedic procedure at a private hospital in Kochi.The family had arrived in an Emirates flight. When the family reported that the girl was having fever, the health officials decided to subject her to the quarantine procedures prescribed by the World Health Organisation. The girl’s parents have also been kept in the observation ward.Her blood samples have been flown to the National Centre for Disease Control (NCDC) at New Delhi to be tested for Ebola virus. Doctors at the Ebola quarantine unit said the test results were expected on Tuesday.If the result is positive, the family will be kept in the isolation ward for at least 21 days, which is the normal incubation period of Ebola virus. The family can be discharged immediately if the tests are negative, a source at the hospital said.Even though there had been several outbreaks of Ebola in the past, this episode in the African countries appears to be the most fatal. About 2,300 people were known to have lost their lives in all the past outbreaks. But, the death toll for the current outbreak that began in mid 2014 is around 10,000.The mortality rate was as high as 90% in the beginning of the latest outbreak. It has now come down to about 50%.Even though Nigeria is now declared as free from Ebola, several passengers from the neighbouring disease-hit countries like Liberia pass through Nigerian airports.
