levels of illness but low death rates in pigs. These viruses may circulate among pigs throughout the year, but most outbreaks occur during the autumn and winter months, similar to flu outbreaks in humans. The classical swine flu virus (an H1N1 virus) was first isolated from a pig in 1930. Like all influenza viruses, swine flu viruses change constantly. Pigs can be infected by avian influenza an...

background emergence of a novel swine-origin influenza a (h1n1) pandemic since 2009 attracted the attention of scientists to characterize epidemiological features and clinical manifestations of this disease in comparison to seasonal flu in different parts of the world. objectives the goal of this investigation was to compare these features in confirmed cases of swine-origin influenza a (h1n1) a...

BACKGROUND During the early stages of the 2009 swine flu (influenza H1N1) outbreak, the large majority of patients who contacted the health services about the illness did not have it. In the UK, the NHS Direct telephone service was used by many of these patients. We used qualitative interviews to identify the main reasons why people approached NHS Direct with concerns about swine flu and to ide...

background: timely notification is of great importance in health emergencies. so identifying the most important sources of information used by people in emergencies seems necessary. the objective of this study was to assess peoples’ level of awareness concerning the symptoms, routes of transmission, prevention, and treatment of h1n1 at the time of the pandemic and also to identify their most im...

The general population is concerned about the probable devastating effects of pandemic H1N1 2009. Based upon the 1918 Spanish flu pandemic, scientific publications and theories, the idea that swine flu parties may achieve passive immunity against pandemic H1N1 2009 has been proposed. Public health officials have asked the general public not to resort to these parties. However, no concrete evide...

The Swine flu outbreak in humans is due to a new strain of influenza A virus subtype H1N1 that derives in part from human influenza, avian influenza, and two separated strains of swine influenza. It can be transmitted from human to human. A mathematical model for the transmission of Swine flu is developed in which the human populations are divided into two classes, the risk and non-risk human c...

Influenza has been recognized as a respiratory disease in swine since its first appearance concurrent with the 1918 „„Spanish flu‟‟ human pandemic. All influenza viruses of significance in swine are type A, subtype H1N1, H1N2, or H3N2 viruses. Swine Influenza is a respiratory disease of pig caused by Type A influenza viruses. Influenza A causes moderate to severe illness and affects all age gro...

Swine influenza (SI) is a respiratory disease of pigs caused by type A influenza that regularly causes pandemics. SI viruses do not normally infect humans; however, human infections with SI do occur, and cases of human-to-human spread of swine flu viruses have been documented. Swine influenza also called as swine flu, hog flu, and pig flu that refers to influenza is caused by those strains of i...

The emergence of a swine influenza virus (H1N1) pandemic strain earlier this year prompted a huge worldwide effort to produce swine flu vaccines in time for the winter flu season. Justine Davies reports.
