What swine flu actually is?

Swine flu is a disease that was common in pigs but has made its way to human body since 2009. It is a contagious respiratory disease caused by the H1N1 virus which a type of influenza virus. Like other flu, swine flu also has a tendency to spread during the flu season which is basically monsoon. Not the only H1N1 virus, it has also been reported that it can even spread from other subtypes, as in such as H1N2, H3N1, and H3N2.

Causes & symptoms of swine flu


A human can get infected with swine flu in one of the 2 ways- either by getting in contact with an infected pig or an infected human.

  • Getting in touch with an infected pig- This is the most common form to get infected. Initially, this disease had only infected pigs and this is how it has spread to humans- by humans getting in contact with the infected pigs.
  • Getting in touch with infected human- Being a highly contagious disease, it spreads very quickly from one human to another through the air. The common mode of getting infected with this flu via humans is through sneezing, coughing. When one infected person sneezes or coughs the surrounding air gets contaminated and this way the virus attacks other people’s body in the neighborhood.


The symptoms of swine flu are no different than other flu, especially similar to those of regular influenza. Let, us have a look at the symptoms: –

  1. Coughing
  2. Fever
  3. Chills
  4. Body Ache
  5. Diarrhea
  6. Sore throat
  7. Running nose
  8. Nausea
