Ebola outbreak over, says WHO
The World Health Organization declared Liberia Ebola-free last January 14, marking the end of the Ebola outbreak in West Africa.
But the Organization says the job is not over, more flare-ups are expected and that strong surveillance and response systems will be critical in the months to come.
January 14 marks the first time since the start of the epidemic 2 years ago that all 3 of the hardest-hit countries—Guinea, Liberia and Sierra Leone—have reported 0 cases for at least 42 days. Sierra Leone was declared free of Ebola transmission on 7 November 2015 and Guinea on 29 December.
“Detecting and breaking every chain of transmission has been a monumental achievement,” says Dr Margaret Chan, WHO Director-General. “So much was needed and so much was accomplished by national authorities, heroic health workers, civil society, local and international organizations and generous partners. But our work is not done and vigilance is necessary to prevent new outbreaks.”
WHO cautions that the 3 countries remain at high risk of additional small outbreaks of Ebola, like the most recent one in Liberia. To date, 10 such flare-ups have been identified that were not part of the original outbreak, and are likely the result of the virus persisting in survivors even after recovery. Evidence shows that the virus disappears relatively quickly from survivors, but can remain in the semen of a small number of male survivors for as long as 1 year, and in rare instances, be transmitted to intimate partners.
WHO and partners are working with the Governments of Guinea, Liberia and Sierra Leone to help ensure that survivors have access to medical and psychosocial care and screening for persistent virus, as well as counselling and education to help them reintegrate into family and community life, reduce stigma and minimize the risk of Ebola virus transmission.
