H1N1 flu pandemic

Generally we know Influenza viruses cause annual endemics and infrequent endemics that have asserted the lives of many peoples. Appreciating the function of particular awareness in encouraging people to engage in preventive activities may help health communicators to progress their messages about epidemics of new contagious infection usually and swine flu in particular. Due to the swine-flu virus called novel swine-origin influenza A (H1N1) the eruption of human infection began all over the world in spring 2009. "H1N1 emerged in February 2009 in Mexico and swept around the globe within 6 months." ( - Professor Hans Dieter Klenk; Philipps-Universität Marburg). Though flu epidemic began in 1918 and it becomes blast as a great epidemic in 2009.[See Table-1] In more than 214 countries during that times swine-flu virus (H1N1) was a severe epidemic public health problem. A laboratory confirmation was required to differ novel influenza virus from seasonal human influenza as all clinical symptoms of novel swine-flu’s infection were similar to seasonal human influenza. Swine-flu Influenza A (H1N1) is a subtype of virus called influenza A and it was common cause of human swine-flu in 2009. H1N1 influenza swine-flu virus now named as novel H1N1 and this influenza virus normally found in pigs. In 1930 in the U.S. swine influenza virus was first isolated from pigs. As the eruption of human infection due to H1N1 influenza virus began all over the world in spring 2009, WHO (World Health Organization) declared swine-flu as a pandemic. Often public media call this strain of swine-origin H1N1 as swine-flu. As swine-flu spread worldwide it caused 1700 peoples death. In 26th April 2011, the World Health Organization (WHO) has issued an H1N1 epidemic preparation alert for all Americans. Chihuahua of Mexico also have included in affected region as here severity of H1N1 influenza-virus have been high.

H1N1 influenza virus has serious impact on the individual health especially on those older than 65, younger than 5 years [See Table-2], children with conditions of neurodevelopment, women who are pregnant (mainly during 3rd trimester) and those who are underlying in many disease like a weakened immune system, diabetes, asthma, obesity, weaken heart. The symptoms of H1N1 flu are similar to other influenzas. Symptoms like fever, joint pain, cough, muscle pain, headache, vomiting and diarrhea has been reported. The CDC reported In September, 2009 that the H1N1 flu "seems to be taking a heavier toll among chronically ill children than the seasonal flu usually does." The CDC had received 36 reports of pediatric deaths associated with swine-flu symptoms and clinically-confirmed through 8 August 2009. Some symptoms of H1N1, swine flu influenza virus are given below:- Symptoms found in children:

* Breathing problem
* Having no tears when crying
* skin color become bluish
* less interacting
* not enough drinking fluids

Most complication will occur for a man/woman who is overweight. Primary influenza generally occurs in adults but among children bacterial influenza is more common. An investigation in United Kingdom reported that about 631 patients become ill with epidemic influenza virus A H1N1 and 55 patients admitted in hospitals confirmed with clinical-proven from April through 2010. Among them 13% admitted in hospitals under doctor’s high investigation and end of all 5% died. 36% were aged under...
