Visual Curvatures of H1N1 Incidences in African, Asian, European, American and Oceanic Nations

The World Health Organization (WHO) was worried about the outbreak of H1N1 epidemic worldwide as it consumed several human lives. In a novel manner, this article defines, computes and illustrates the effectiveness of health administrators’ efforts to extinguish pandemic H1N1 using curvature concept. Data on weekly incidences of H1N1 in year 2009 among the nations in Africa, Asia, Europe, Americas and Oceanic continents are utilized to compare continents and nations within the continent. A knowledge discovery from the data analysis of 2009 incidences is a necessity before any future incidences erupt. For stochastic reasons, which are stated and explained in the article, an Incidence Rate Restricted Inverse Binomial Distribution (IRRIBD) is introduced in this article to be an appropriate underlying model for the data. The plasticity of IRRIBD to explain the dynamics of the influenza is investigated. The actual H1N1 incidences during 2009 are analyzed and interpreted using IRRIBD in the illustration.
