Recurrence of Ebola transmission in Liberia
On 9 May 2015, Liberia marked an important milestone in the management of their Ebola outbreak. On that day, the country was declared free of Ebola transmission because no new cases had been identified for 42 days after the safe burial of the last person confirmed to have been infected with Ebola virus disease.
Although transmission of the virus had ceased, Liberia remained at high risk of a recurrence of Ebola due to ongoing transmission in neighbouring Guinea and Sierra Leone. For this reason Liberia then entered a 90-day period of vigilance involving testing anyone with features of Ebola virus disease and testing post-mortem swabs for Ebola virus.
