H1N1 or Swine Flu is a highly infectious seasonal illness caused by Influenza type – A virus. Although Swine flu derives its name from an infection that affects pigs, the H1N1 strain affects humans and does not involve any pigs in transmission. In 2009 the fast spread of the infection across the world, made WHO declare it as a pandemic infection.

Quite similar to a regular flu, most patients get mild to moderate illness that requires some rest, plenty of fluids and medicines to manage the fever and body pain. The illness can be become complicated if it develops into pneumonia/ breathing problem or a lung infection. Symptoms like shortness of breath, severe vomiting, pain in belly or sides, dizziness, or confusion may need immediate attention.
