H1N1 Influenza Virus 2
H1N1 is a new influenza virus causing illness in people. This virus was first detected in residents of the United States in April of 2009. This virus is contagious and is spreading from person to person worldwide just as seasonal flu viruses spread. According to Up To Date (2009), the month of July in the United States contained 43,000 confirmed cases of H1N1 reported from 55 states and territories. The World Health Organization (WHO) raised its pandemic alert level to the highest level, phase 6. The characteristics of pandemics are their rapid spread to all parts of the world. According to American Medical Association (H1N1 news, n.d.), as of November 12, 2009, data from April 2009 through October 17, 2009 indicates that: there is a total of 20 million people became ill with H1N1, 98,000 hospitalized, and 3,900 deaths. In the age group of eighteen years old and younger, eight million people were ill, 53,000 were hospitalized, and there were 540 deaths. Ages 65 and greater had two million ill, 9,000 hospitalized and 440 deaths (n.p.).
