In 2009 swine flu caused significant distress and multiple deaths globally. First found in Mexico in early 2009, and it rapidly spread across the world and has received public attention and pandemic alert. Swine Flu is described as as Swine-origin influenza A(H1N1) virus (S-OIV), differentiating it from other numerous existing viruses known to have existed in pigs for many years (Belshe 2009). The unique characteristics of swine flu virus are its ability to transmit from one person to another. In the majority of cases the symptoms of swine flu are cough, running nose, sore throat, nausea, vomiting, diarrhea, or loss of appetite, muscle aches, lethargy/loss of energy. In some cases, it may lead to severe, fatal disease in which patients develop pneumonia and respiratory failure. In some intense cases, patients require admission to intensive care, invasive ventilation, and occasionally the use of extracorporeal membrane oxygenation (ECMO).
In 2009, around 414,000 cases of Swine Flu were confirmed globally and which has resulted in deaths from the disease that were estimated at approximately 5,000 worldwide in 2009 (WHO 2009a). In Australia alone, over 37,000 cases of swine flu were confirmed, resulting in almost 5,000 hospitalizations and at least 186 deaths (DOHA, 2009a). The majority of deaths in Australia occurred in New South Wales which is about 13% of the total number of the cases.
A pandemic is a widespread of infectious disease that has spread through human populations across a large region; for instance multiple continents, or even worldwide. In other words, it is a disease occurring worldwide or over a very wide area, crossing international boundaries, and usually affecting a large number of people. There are different examples of pandemics found throughout history such as plague, influenza, cholera, HIV/AIDA, swine flu etc.
