Sierra Leone Reports New Ebola Case Just Hours After Region Declared Free of Virus

On 15 January, Sierra Leone officials confirmed a death of Ebola, just hours after the World Health Organization (WHO) declared the latest West Africa outbreak over.

According to an Ebola test centre spokesman, tests on a person who died in northern Sierra Leone proved positive. Sidi Yahya Tunis disclosed that the death occurred earlier this week and that the patient had died in the Tonkolili district, adding he had travelled there from Kambia, which is located close to the border with Guinea. The victim was a 22-year-old female student. According to district medical officer Augustine Junisa, “the victims was taken ill when she was on holidays in Bamoi Luma and was taken to Magburaka, where her relatives took her to the government hospital for medical attention…Three days later she died at home and her death was reported to the hospital officials and initial swap test was taken which proved positive.” Sources have reported that health officials are now urgently seeking those who had come into contact with the victim.

Sierra Leone was declared free of the virus on 7 November 2015, and the region as a whole was cleared when Liberia was pronounced Ebola-free on 14 January. While the WHO has warned that flare-ups are expected, Friday’s announcement of a new case in the region is a setback for the area. Already, ten other flare-ups have taken place in areas where the spread of Ebola was thought to have ended, effectively raising new questions about WHO procedures in assessing whether the epidemic was really over. On Friday, the UN Health agency reported that Sierra Leone’s government was moving rapidly in order to contain the new threat, noting however that it was not immediately clear how the 22-year-old woman may have contracted Ebola as all known transmission chains in that country were halted in November. 

Timeline of Ebola Epidemic in West Africa

Below are key dates in the latest Ebola epidemic, which is the worst outbreak of the haemorrhagic fever, which first surfaced in 1976 in what is now the Democratic Republic of Congo (DRC). According to the latest toll released by the WHO, the epidemic has left more than 11,300 dead, mainly in the West African countries of Guinea, Liberia and Sierra Leone. Almost 29,000 cases were reported during the outbreak.

Epidemic Starts in Guinea:

• December 2013: A one-year-old baby dies in southern Guinea and is later identified as “patient zero.” The virus remains localized until February 2014, when a care worker in a neighbouring province dies.

Ebola Begins to Spread in West Africa:

• 31 March 2014 – Two cases are confirmed by the WHO in Liberia, while on 26 May, Sierra Leone confirms its first case, to be followed in late July by Nigeria, in August by Senegal and in October by Mali. Senegal and Nigeria are declared free of Ebola in October 2014 while Mali is declared Ebola-free in January 2015.

Guinea, Liberia, Sierra Leone Cut Off From The World:

• 30 May 2015 – According to the aid group Doctors Without Borders (MSF), Ebola is “out of control.” The three worst-hit countries – Guinea, Liberia and Sierra Leone – declare measures that include states of emergency and quarantines. Many neighbouring states close their borders with the affected countries.

A ‘Public Health Emergency’:

• 8 August 2014 – The WHO declares Ebola a “public health emergency of international concern.” Four days later, it authorizes the use of experimental drugs in order to fight Ebola after an ethical debate. That day, a Spanish missionary infected in Liberia dies in Madrid, becoming the first European fatality.

Death in the US:

• 30 September 2014 – A Liberian man is hospitalized in the US state of Texas, effectively becoming the first Ebola infection to be diagnosed outside of Africa. He dies on 8 October.
• 6 October 2014 – A Spanish nurse in a Madrid hospital becomes the first person to be infected outside Africa. She is treated and released on 19 October.

Ebola Begins a Halting Retreat:

• 22 February 2015 – Liberia says it is lifting nationwide curfews and re-opening borders, as the epidemic begins to retreat.
• 26 February 2015 – The US ends its military mission in West Africa, where it deployed 2,800 soldiers in order to fight against Ebola. Soldiers were mainly deployed to Liberia.

Closing in on a Vaccine:

• 10 July 2015 – International donors pledge US $3.4 billion in order to help stamp out Ebola.
• 31 July 2015 – The WHO says an Ebola vaccine provided 100-percent protection in a field trial in Guinea, suggesting that the world is “on the verge of an effective Ebola vaccine.”

Hardest-hit Countries Emerge from the Epidemic:

• 9 May and 3 September 2015 – Liberia is declared Ebola-free by the WHO after no new cases were recorded for 42 days. However the declarations are followed by a resurgence of the virus. On 4 December, Liberia releases from hospital its last two known Ebola cases.
• 7 November 2015 – Sierra Leone is declared free of the outbreak by the WHO.
• 29 December – The WHO declares Guinea’s Ebola outbreak over, six weeks after the recovery of its last known patient, a three-week old girl who was born with the virus.
