(AFP) – German health authorities Tuesday took to hospital and quarantined a 30-year-old West African woman who showed symptoms consistent with the deadly Ebola disease.

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.

The mass-circulation Bild daily said the woman had fainted, that she hailed from Nigeria and that she said later that 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.

West Africa’s Ebola epidemic, which has hit four nations since it broke out in Guinea early this year, is by far the deadliest since the virus was discovered four decades ago in what is now the Democratic Republic of Congo.

The UN World Health Organization said Tuesday the Ebola virus had killed 84 people in just three days, bringing the global death toll to 1,229, while confirmed, probable and suspect infections rose to 2,240.
