The cause of atypical respiratory illness in several Mexican states in mid-March 2009 was determined to be a novel pandemic (H1N1) 2009 virus. It has since then spread to six continents, causing illness and death. We review this virus against an epidemiological triangle model for understanding and visualizing communicable diseases that describes the interaction of an agent, host, and environment. We review the agent, i.e., pandemic (H1N1) 2009 virus, hosts focusing on human beings, and the environment, suggesting from this agent-host-environment interaction measures for controlling and preventing infection spread due to pandemic (H1N1) 2009 virus and the related issues.
