Ebola: Setback as new case found one day after outbreak declared over

A corpse has tested positive for Ebola in Sierra Leone, an official said Friday, the day after the World Health Organization (WHO) declared the outbreak over in West Africa.

Tests on a 22-year-old woman who died earlier this month in Sierra Leone’s north proved positive for the virus, Francis Langoba Kellie, spokesman for the Office of National Security, told a local radio program.

She came from the Northern Kambia District and went to the Northern Tonkolili District for medical attention, he said.

Authorities are tracing her contacts and have dispatched teams to the area for investigations. Certain areas will be quarantined, he said.

WHO declared an end to the deadliest Ebola outbreak ever on Thursday after no new cases emerged in Liberia. It had been at least a month since Ebola had been seen in Guinea or Sierra Leone – the 3 countries were most affected by the epidemic that began 2 years ago.

“Our level of preparedness and response capabilities are very high and there is no cause for concern,” said Kellie. “We encourage the public to continue to practice the hygiene regulations which were in force during the period while Ebola was raging and the emergency regulations are still in force.”

Nearly 4,000 people had died before Sierra Leone was declared free from transmission of Ebola on November 7. Guinea marked that day on December 29.

Liberia was first declared free of the disease in May, but new cases emerged 2 times – forcing officials there to restart the clock. Thursday marked its third time being declared free from transmission.

Ebola has killed more than 11,300 people, mostly in West Africa, since it emerged at the end of 2013.

The WHO declares Ebola transmission over when a country goes through 2 incubation periods – 21 days each – without a new case emerging. Countries are then placed on a 90-day heightened surveillance.

Ebola is spread through direct contact with the bodily fluids of people who are sick or bodies of the dead.
