What is influenza A?

Answer 1

Influenza is an infectious disease of the respiratory tract that is caused by influenza viruses. It is often called the flu.

Answer 2

What is avian influenza? Well we will start with the word "avian" which derives from the Latin word "Aves" meaning bird. Influenza is the "flu" so it means - bird flu.

Avian influenza (bird flu) is caused by strains of influenza A (influenza A is a virus that has a negative single- stranded, segmented RNA genome).

The bird flu is most prevalent among wild birds - go figure. Infections with influenza A in wild birds is asymptomatic but can cause highly lethal illness in domestic birds.

Mutations may occur in the avian influenza thro error-prone RNA polymerase making small changes in the genetic code of the virus, and may ultimately be able to infect humans. Although the influenza virus in birds cannot directly infect humans, pigs are easily susceptible to the mutated bird flu, and from pigs humans are prone to acquire it. This explains why Asia is the most common place epidemics occur (because ducks, pigs, and humans are in close contact.)

Answer 3

* Influenza Type A is the most common and also the scariest of the three influenzas, causing the most serious epidemics in history. * Influenza Type B flu outbreaks also can cause epidemics, but the disease it produces generally is milder than that caused by type A. * Influenza Type C flu viruses, on the other hand, have never been connected with a large epidemic, usually just causing mild respiratory infections similar to the common cold.

Answer 4

Influenzavirus A uses wild aquatic birds as hosts. Occasionally it is transmitted to other species and may then cause devastating outbreaks in domestic poultry, or give rise to human influenza pandemics. The type A influenza viruses are the most virulent human pathogens among the three influenza types and cause the most severe disease.

Answer 5

Influenza is an infectious disease of the respiratory tract that is caused by influenza viruses. It is often called the flu.

Answer 6

Influenza A is a commonly found type of flu that is found in mainly mammals. It is a type of virus that is most commonly found to harm the throat, nasal, head, and lungs.

Answer 7

The Influenza(flu) is caused by three stains of virus-influenza A,B,and C.It passes from person to person by airborne transmission .

Answer 8

Influenza is the flu. The word "flu" is the abbreviated version of influenza. It is a virus.

Answer 9

A respiratory disease caused by a viral infection. It is an acute febrile disease (gives a high fever), highly contagious, and can be deadly especially to the elderly and babies.

there are three types of influenza type a type b and type c
