How does flu spread so quickly? When the infected person breathes out, sneezes or coughs, he gives out droplets of moisture in the breath from his mouth or nose. These remain in the air for some time. Flu viruses are present in these droplets. If a person sneezes in a crowd or poorly ventilated place, such as a lift, viruses can easily be carried from an infected person to a healthy person. This is known as droplet infection. The healthy person will breathe in the viruses given out by the infected person.

There are three main types of virus that cause flu, which are called type A, B and C. type A is the most powerful of the three, and undergoes minor changes in its genetic material every few years. The new form of the virus is called a strain. The new strain is not affected by the current vaccines. It is said to be “resistant” to them. So doctors must be continually producing new vaccines to combat the new strains of virus.
