Swine flu or H1N1 flu virus: Symptoms and Prevention

Swine flu, also known as the H1N1 virus, is a comparatively recent strain of influenza, that originates in pigs but is mainly transmitted from one person to another. If we consider the technical meaning, this type of flu mainly refers to influenza in pigs. However, affected pigs might transmit the infection to humans, in occasional circumstances.

Swine flu was observed in MEXICO for the first time, and emerged in the year 2009, when the scientists came across a strain of flu virus that was referred as H1N1. It was responsible for the production of various respiratory symptoms, collectively referred to as SWINE FLU. It was soon declared by WHO as a global pandemic, as people from all around the world got affected.

How does swine flu spread?

• The transmission only occurs from one person to another, and not from animal to person.
• It is extremely contagious and is transmitted via ingestion or inhalation of droplets loaded with viruses, when coughing or sneezing.
• It must be noted, that contrary to the common belief, swine flu is not transmitted by consumption of cooked pork.
