INFLUENZA A Meaning and
Definition
-
Influenza A, commonly referred to as the flu, is a highly contagious respiratory illness caused by the Influenza A virus. It is one of the three types of influenza viruses, the others being Influenza B and Influenza C. Influenza A is considered the most severe and dangerous type, as it has the potential to cause pandemics and widespread outbreaks.
The Influenza A virus belongs to the Orthomyxoviridae family and is further classified into subtypes based on the presence of specific proteins on its surface: hemagglutinin (H) and neuraminidase (N). There are currently 18 known H subtypes and 11 known N subtypes, with numerous combinations possible.
Influenza A is transmitted through respiratory droplets when an infected person coughs, sneezes, or talks, and can also spread by touching surfaces contaminated by the virus. Symptoms of Influenza A can include high fever, cough, sore throat, fatigue, body aches, headache, and sometimes gastrointestinal issues.
Due to its ability to undergo frequent genetic changes, Influenza A can cause seasonal epidemics and occasional pandemics with severe consequences. Vaccines are available to help prevent the spread of Influenza A and reduce the severity of symptoms. Antiviral medications can also be prescribed to treat the infection and lessen its impact. However, it is important to note that the effectiveness of the vaccines and antiviral drugs may vary depending on the specific subtypes and strains of the Influenza A virus circulating in a given season.

Etymology of INFLUENZA A
The term influenza originates from Italian, from the medieval Latin word influentia, which means influence. The use of this term can be traced back to the belief that the disease was caused by the influence of astronomical bodies, such as the alignment of the stars or the movement of planets. The letter A in influenza A refers to the specific type of influenza virus, also known as influenza type A.
