UN: New Ebola case in Sierra Leone prompts use of experimental vaccine trial - WHO

New York, US (PANA) - The World Health Organization (WHO) on Tuesday said that the detection of a new case of Ebola in Sierra Leone over the weekend, after the West African country had marked almost three weeks of zero cases, has prompted the use of an experimental vaccine to fight the disease.

"Although no-one wanted to see more cases of Ebola virus disease in Sierra Leone, we kept
all our teams on alert and ready to respond and close down any new transmission," Dr. Anders
Nordstrom, WHO Representative in Sierra Leone said in a statement obtained by PANA in
New York.

WHO disclosed that a team of experts conducting the so-called "ring vaccination" trial in
Conakry, Guinea, travelled to Kambia district in Sierra Leone where the new case was
reported on Saturday

It said the source of the Ebola virus transmission is being investigated and all the people
who may have been in contact with the infected person are being traced.

It also noted that interim results published in July showed that the Guinea ring vaccination
trial vaccine was highly effective against Ebola.

The 'ring vaccination' strategy involves vaccinating all contacts – the people known to have come into contact with a person confirmed to have been infected with Ebola – and contacts of contacts.

WHO said that heightened surveillance for Ebola virus disease in Sierra Leone includes
swabbing all people who have died at home and testing those swabs for Ebola virus.

It added that on 29 August, a swab taken from a woman who died aged around
60 in the village of Sella, Tonko Limba, Kambia district, tested positive for Ebola virus.
