While cases of H1N1 influenza are again on rise in some parts of India. Hospitals report a mix of flu cases, and other respiratory infections.

Swine flu – know its causes

Swine flu is a highly contagious respiratory infection caused by the H1N1 virus. The cause of swine flu in humans is another infected person transmitting it to you. So, coming in close contact with an infected person puts you at high risk. 

How does the swine flu virus spread? The virus spreads quickly from one person to another through the cough or sneeze droplets from an infected person. Even a simple cough can cause the virus to spread in the air and enter through your nose or mouth. You may also be infected with the flu virus lingering on the surface of certain objects like a doorknob or a table by coming in direct contact with it. 

Although outbreaks occur Today, the virus is under control, but people can and do still get very sick from H1N1. It’s important to get your yearly flu shot, which can protect you from H1N1 and other strains of the flu.
