A 30-year-old woman who has allegedly hailed from Nigeria and been in contact with Ebola-positive people has been took to hospital and quarantined as she showed symptoms consistent with Ebola disease, German health authorities said. According to AFP, dozens of other visitors and staff at a Berlin employment office building were also stopped from leaving for several hours as emergency services sealed off part of the street. It was gathered that the woman who had fainted later said she had recently been in contact with people infected with Ebola. Several people who had been with the woman inside the building in the northeastern district of Prenzlauer Berg were later also taken to hospital for testing. Berlin fire department spokesman Rolf Erbe said that because the patient came from “an area affected by a highly contagious disease, we took these precautions.” He said the testing in the city’s Charite hospital would take some time. “The patient was isolated inside the ambulance, the staff took the appropriate protective measures. An emergency medic, the public health officer, arrived and the necessary precautions were taken,” he added. The Ebola outbreak that has killed more than 1,100 people in West Africa could last another six months, the Doctors Without Borders charity group said Friday. One aid worker acknowledged that the true death toll is still unknown.
