H1N1 Virus Description

This virus is classified as an avian virus and the virus is believed to be first found in birds, mainly the ducks from which it is transmitted to the pigs and then it finally infects humans. This virus needs to be understood because it has been associated with many outbreaks throughout the world and it is also believed that such outbreaks serve to be an economic burden and a reason for morbidity and mortality (Brooks et al 2004).The history of H1N1 virus dates to the beginning of the twentieth century and there have been many outbreaks due to this virus along with a very high rate of fatalities. The first outbreak due to this virus was reported in the year 1918. It was a pandemic and the estimated number of deaths was so high that it was said that the deaths due to this outbreak were more than the total number of people who died in World War 1 and 2, the Korean War as well as the War of Vietnam (Levinson 2008). It was analyzed that approximately 50 million people died due to this outbreak and at the same time an illness among pigs assisted the scientists to reach to a decision that this illness had been contracted from the pigs (Zimmer and Burke 2009). In 1930, the virus was found in pigs in the United States and occurrence of disease in the animals was reported. In particular, the season of winter is optimum for the occurrence of this virus (CIDRAP). Ever since then, there were cases of influenza due to this virus but no significant outbreaks. In 1957, the virus got completely eradicated and it was in the 1970s that this virus reemerged. In 1976 there was an outbreak at an army base in New Jersey and many soldiers were affected. In the year 1977, a global pattern was reported with the Soviet Union, China, and Hong Kong
