If you haven’t heard of H1N1 influenza (flu), chances are you’re probably aware of it via its more common name, Swine flu. It is so called because when it was first detected it was very similar to a flu virus carried by pigs.
In 2009, swine flu was responsible for a flu pandemic that originated in Mexico and spread throughout countries across the world. Fortunately, it wasn’t as severe as first thought and in 2010 the World Health Organization declared the pandemic was over.
But the risk of swine flu still remains, H1N1 influenza is one of the main flu strains that continues to circulate with the elderly, pregnant women, and people suffering from heart, lung, kidney and liver disease particularly at risk of complications.
