In a previous post (Ebola is not yet under control in any West African country), I criticized an article that suggested that Ebola infections were declining in several countries in West Africa because the effective reproductive rate was less than 1.
The graph below depicts the number of new weekly infections in the three West African countries (Guinea, Liberia, and Sierra Leone). Cumulatively, the number of Ebola infections is continuing to grow. The World Health Organization has indicated today (link) that these countries have widespread intense transmission of Ebola.
Graph notes: The data used in this graph are derived from World Health Organization and are current through August 31, 2014. Graph notes: Only cases from the Ebola outbreak in Guinea, Liberia, and Sierra Leone are used in this graph. The cases from Nigeria are not included in the week totals, but would not appreciably affect the projected rate of growth of new cases. All data are from WHO.
