The identification of these early cases marked the beginning of the West Africa Ebola epidemic, the largest in history.

Summary The initial case, or index patient, was reported in December An month-old boy from a small village in Guinea is believed to have been infected by bats.

After five additional cases of fatal diarrhea occurred in that area, an official medical alert was issued on January 24,to the district health officials. By Julythe outbreak spread to the capitals of all three countries. This was the first time EVD extended out from more isolated, rural areas and into densely populated urban centers, providing an unprecedented opportunity for transmission.

Over the duration of the epidemic, EVD spread to seven more countries: Later secondary infection, mainly in a healthcare setting, occurred in Italy, Mali, Nigeria, and the United States. The scope of this outbreak, both in terms of cases and geography, can be attributed to the unprecedented circulation of EVD into crowded urban areas, increased mobilization across borders, and conflicts between key infection control practices and prevailing cultural and traditional practices in West Africa.

Engaging local leaders in prevention programs and messaging, along with careful policy implementation at the national and global level, helped to eventually contain the spread of the virus and put an end to this outbreak. Liberia was first declared Ebola-free in May Additional cases were found and treated, and the country was again declared Ebola-free in September After this, more cases were discovered again, until finally on January 14,Liberia announced it was Ebola-free and no additional cases have been detected since.

After an initial declaration in NovemberSierra Leone announced it was Ebola-free on March 7, A preliminary statement in December was retracted when additional cases were discovered in March and April and Guinea was finally declared Ebola-free in June Ebola in the United States Overall, eleven people were treated for Ebola in the United States during the epidemic.

The patient the index case died on October 8, Two healthcare workers who cared for him in Dallas tested positive for EVD. The diagnosis was confirmed by the CDC the next day.

Seven other people were cared for in the United States after they were exposed to the virus and became ill while in West Africa, the majority of whom were medical workers. They were transported by chartered aircraft from West Africa to hospitals in the United States.

Six of these patients recovered, one died. CDC personnel deployed to West Africa to assist with response efforts, including surveillance, contact tracing, data management, laboratory testing, and health education. CDC staff also provided support with logistics, staffing, communication, analytics, and management.
