New Delhi/Ahmedabad: Health authorities have intensified airport surveillance, passenger monitoring and quarantine measures after suspected Ebola cases were reported in Bengaluru and Gujarat, although no Ebola infection has been confirmed in India so far.A 28-year-old Ugandan woman, who was isolated in Bengaluru on suspicion of Ebola infection, has tested negative for the virus, in a relief amid heightened global concern over the fresh outbreak in parts of Africa.Officials said Airport Health Organization (APHO) teams are directly contacting passengers arriving from affected countries and are also isolating individuals with mild symptoms as a precautionary measure. “Even if someone complains of a minor headache, we do not want to take any risk and are keeping such persons in isolation,” an official said, adding that the samples are being sent to the National Institute of Virology (NIV) for testing.A sample of a suspected case from Gujarat has been sent to the National Institute of Virology (NIV), Pune, for testing and results are expected in 24 to 48 hours, officials said.The Gujarat case involves Amuri Lokula, a 37-year-old man who allegedly traveled through the African continent and Bangladesh before reaching Mumbai and later Vadodara for business purposes along with two associates. He was quarantined at the Civil Hospital in Ahmedabad on Wednesday.According to health officials, the man developed symptoms of fever, cold and cough and was admitted to a private hospital in Vadodara before being shifted to the special Ebola ward set up at the Ahmedabad Civil Hospital after his travel history was revealed during screening.His two colleagues and a doctor who came in professional contact with him have all been kept under observation as a precautionary measure, officials said.
