What is swine flu? - Dr. Cajetan Tellis

Swine flu started in 2009 and the spread happens person to person or person to surface to person.
When a person who has swine flu coughs or sneezes, the droplets that contain the virus spread all over in the air and if there is anyone nearby and inhales the same air, they could get swine flu.
Alternatively, it can spread if the droplets fall on some inanimate objects like a door knob or a tap. If the person sneezes into the hand and then touches either another persons hand, for eg. shaking the hand, opens a tap or touches a door knob and somebody else touches them, they can get it.
The people who have swine flu are contagious one day before they get the symptoms. So you may not know whom to stay away from if anyone is coughing or sneezing badly.. nnPeople are also contagious for a full week into the disease and children are contagious ten days after they get the symptoms..
