Significance

Since the initial recognition of Ebola virus disease (EVD) in 1976, many epidemics have occurred in Africa. Serious concerns remain that the fatal disease may repeatedly reemerge. In this study, we used data from an unprecedented EVD outbreak in Sierra Leone to map spatiotemporal transmission patterns, identify influential factors, and assess the effects of interventions at the chiefdom level. Furthermore, we have quantified household transmissibility and the temporal association between interventions and household transmission. Our findings have deepened the understanding of the transmission dynamics of EVD and provided key information for future modeling efforts in forecasting future epidemics and establishing intervention strategies.

DAKAR, Senegal --Lingering health problems afflicting many of the roughly 13,000 Ebola survivors have galvanized global and local health officials to find out how widespread the ailments are, and how to remedy them.

The World Health Organization calls it an emergency within an emergency. Many of the survivors have vision and hearing issues. Some others experience physical and emotional pains, fatigue and other problems. The medical community is negotiating uncharted waters as it tries to measure the scale of this problem that comes on the tail end of the biggest Ebola outbreak in history.

"If we can find out this kind of information, hopefully we can help other Ebola survivors in the future," Dr. Zan Yeong, an eye specialist involved in a study of health problems in survivors in Liberia, told The Associated Press.

About 7,500 people will enroll — 1,500 Ebola survivors and 6,000 of their close contacts — and will be monitored over a five-year period in the study launched by Partnership for Research on Ebola Vaccines in Liberia, or PREVAIL.

ELMINA, Ghana – Each evening the fishermen set out in their hand-carved wooden boats. By nightfall, the horizon is dotted by a long row of small lights, their own constellation. Fish are caught, the haul is sold in markets and life continues. But one group is noticeably absent from Elmina and other towns along Ghana’s coast – tourists.

Thousands of college students embark on a trip to see the world and do a bit of learning through the Semester at Sea program. The West African countries of Senegal and Ghana are usually on the itinerary, bringing a steady flow of tourism to the two countries. But the countries are not destinations for three consecutive semesters due to concerns about Ebola.
