This document provides an update on modeling the 2014 Ebola outbreak in West Africa. It summarizes epidemiological data from Guinea, Liberia, and Sierra Leone. Compartmental models are described and fitted to outbreak data from each country. While many parameter combinations can fit the data, projections remain uncertain without more information. Behavioral changes may eventually curb transmission, but the outbreak could last 6-18 more months. Preliminary US estimates suggest few additional cases may occur if the virus is imported but undetected.
