What is it?

influenza viruses

Influenza is basically a viral infection which attacks the respiratory tract and majorly affects the throat, nose, and even lungs in serious cases. The symptoms of influenza usually start emerging from the first day to the fourth day right after infection. They may also appear all of a sudden. For most of the persons, a session of this infection is an extremely unpleasant and irritating one. But it does not actually stay for long since it is one of the most short-lived physical issues. For other people, however, it can create major health complications, particularly if risks of suffering from pneumonia arise.

Outbreaks of influenza tend to attack people annually and that too at around the same period in every calendar year. Each outbreak may happen by various subtypes or strains of viruses, so each year another variety of vaccine may be needed for the prevention of flu.

Kinds of influenza

Kinds of influenza

There are numerous types of viruses which cause influenza and the list includes multiple subtypes as well as strains.There are three major kinds of influenza viruses i.e. A, B, and C. Influenza A virus and B virus are the reasons behind annual epidemics of seasonal influenza. On the other hand, Influenza C creates milder illnesses and is hardly capable of causing epidemics. Influenza A can also infect a number of birds, mammals including humans; whereas B and C types infect mostly human beings.

Influenza A

This particular type is divided into a few subtypes that are based on the kind of two proteins – abbreviated N and H staying on the virus’s surface. These subtypes are also categorized into multiple strains.Every strain of influenza A does vary a lot as per their species of infection and the serious illnesses they cause. All strains of influenza A viruses are not competent to infect humans.

Influenza B

Influenza B viruses can be categorized into strains as well as lineages rather than their subtypes. These viruses are pretty much capable of causing severe illnesses.One or two sorts of B viruses are largely included in the yearly fever vaccines. The trivalent vaccine that contains three virus components does include one and the quadrivalent vaccine which contains four virus components does include two B type viruses.

Influenza C

 This specific type is responsible for causing infections of upper respiratory tract in kids. C viruses are usually not included in the influenza vaccines and they circulate in a much slower rate than A and B types.

Influenza viruses undergo constant changes via mutations and that is the reason why one needs a new kind of influenza vaccine every single year.The influenza viruses change so much each year that the human immune system is incapable of recognizing them from one year right to the next. These yearly changes are known as antigenic drift and they occur in all the three types i.e. A, B, and C.
