A country is declared free of human-to-human transmission of the Ebola virus after it completes a two 21-day incubation period after the last confirmed case has tested negative a second time.
Guinea has successfully crossed the 42-day period and Guinea now enters a 90-day phase of heightened surveillance to ensure that new cases, if any, are quickly detected before they spread to other people.
The town of Gueckedou in Guinea was the ground zero for the deadly outbreak of Ebola Virus Disease (EVD) and was the last West African state to break the original chain of transmission which killed 11,300 people in the three states of Liberia, Sierra Leone and Guinea.
"This is the first time that all three countries – Guinea, Liberia and Sierra Leone – have stopped the original chains of transmission that were responsible for starting this devastating outbreak two years ago," World Health Organization (WHO) Regional Director for Africa Dr Matshidiso Moeti said.
EVD which started in late December 2013 spread to seven other countries by land and air travel apart from severely affecting the nearby states of Sierra Leone and Liberia.
Sierra Leone was declared free of Ebola in November this year. It saw 3,955 deaths and 14, 122 cases in the last two years. Liberia was declared Ebola-free earlier in September. The deadly disease killed more than 2,500 people in the country and a further 9,000 in Sierra Leone and Liberia.
