How is the h1n1 influenza virus spread?

By droplets in the air,,so by coughing or sneezing and even touhing a surface that has been contaminated by the virus

Sorry this is a little late, but here you go:

Spread of the 2009 H1N1 virus is thought to occur in the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing, sneezing or talking by people with influenza. Sometimes people may become infected by touching something – such as a surface or object – with flu viruses on it and then touching their mouth or nose.

BTW I just did this and got it right.

Hope this helped :)

Explanation:

This is because H1N1 germs can spread through the air and through physical contact.

the areas around the equator

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
