Sierra Leone down to last chain of Ebola transmission

17 August 2015  •  Author: Victoria White

The World Health Organisation (WHO) has reported that the use of rapid response teams and strong community involvement in finding Ebola virus disease cases and contacts is yielding results in Sierra Leone.


An epidemiological week has now passed with no new Ebola cases for the first time since the beginning of the outbreak.

“This is very good news but we have to keep doing this intensive working with communities to identify potential new cases early and to rapidly stop any Ebola virus transmission,” said Dr Anders Nordstrom, WHO Representative in Sierra Leone.

The Ebola response has moved to “phase 3″’, focusing on tracking each and every chain of Ebola virus transmission and closing down the remaining chains as quickly as possible. Sierra Leone is now down to a single chain of transmission, which started in Freetown but sparked a cluster of cases in Tonkolili, in the northern region of the country.

Effectively tracking chains of transmission means finding every person who has been in contact with someone proven to be infected with Ebola, monitoring them closely for symptoms for 21 days and rapidly moving them to a treatment centre if they develop symptoms of potential Ebola.

In Tonkolili, a young man, who worked in Freetown but returned to his home village every month to bring food and money to his extended family, died in a hospital where he was being treated for malaria. As is done with all deaths, to ensure no case of Ebola is missed, a swab was taken. It tested positive for Ebola.

The government, WHO and other UN and international partners sent a rapid response team into the district and worked with the village chief and village taskforce to identify and monitor everyone who had been in contact with the young man.

The entire village of Massessehbeh was then put in quarantine for a period of 21 days, as was Masenga Hospital where the young man died. A water supply was established in the village and food was brought in daily. Psychosocial workers and social mobilisers provided information and support, while contact tracers checked everyone daily for symptoms of Ebola.

Two more people, both of them from the young man’s family, developed symptoms and tested positive for Ebola. They were treated at an Ebola Treatment Centre which had been on standby and run by International Medical Corps (IMC). There they were cared for by a team that included Ebola survivors, who provided much of the physical and psychological care they needed. Both are now recovering.

Last Friday, 595 people “graduated” from quarantine in Tonkolili. This included members of the community and patients, pregnant women, nurses, doctors and other staff who were released early on Friday morning from the hospital where they had been confined for 21 days. Later that day, a formal ceremony was held at Massessehbeh during which the President of Sierra Leone formally cut the quarantine tape.

Joyful villagers streamed through the cut quarantine tapes, women linking arms to dance along the road, children beating water bottles in time to the singing and dancing.
