While the news is encouraging, there are still hundreds of contacts who are undergoing followup check-ins to make sure they stay healthy and the agency says the risk of transmission remains high. “Case incidence has remained below 10 confirmed cases per week for 11 consecutive weeks,” the WHO writes in a statement. “Over the same period, transmission of the virus has been geographically confined to several small areas in western Guinea and Sierra Leone, marking a transition to a distinct, third phase of the epidemic.” For a country to be declared Ebola-free, it must go 42 days without reporting a new case of the disease. The most recent case numbers from the WHO show that since the beginning of the outbreak there have been a total of 28,421 people who have been infected in the hardest hit countries of Sierra Leone, Guinea and Liberia since the start of the outbreak. Among those infected, a total of 11,297 people have died.
