World Health Orginaziton (WHO) announced on Wednesday that no new ebola cases were reported in West African countries in the past week. New cases of ebola have decreased this year but WHO warned that there was still a risk of revival of the epidemic.
So far, more than 28,000 people have been effected and more than 11,000 people have died from ebola in Guinea, Liberia and Sierra Leone according to WHO.
WHO stated in its report "Over 500 contacts remain under follow-up in Guinea, and several high-risk contacts associated with active and recently active chains of transmission in Guinea and Sierra Leone have been lost to follow-up,"
Liberia has already announced that the country is free of the epidemic and that the second time it received declaration concerning being free of the disease was on September 3 after the outbreak in June.
Sierra Leone recorded its last Ebola patients on 28 September and is counting 42 days to become Ebola free. However, the country still remains under examination.
Guinea’s last case was recorded on September 27.
However, health officials have lost track of some people who were regarded as high-risk contacts in Guinea and Sierra Leone.
"Efforts to trace these missing contacts and mitigate the risk of any undetected transmission will continue until at least 42 days have elapsed since the last reported case in each district," WHO said.
In these three African countries, there have been 28,421 cases and recorded 11,297 deaths since the epidemic broke out last year.
