FLU VIRUS Meaning and
Definition
-
The flu virus, also known as influenza virus, is a highly contagious microorganism that infects the respiratory system of humans, birds, and some mammals. It belongs to the Orthomyxoviridae family and is characterized by its ability to rapidly mutate, leading to the emergence of new strains and seasonal outbreaks. The virus possesses a protein coat with surface glycoproteins called hemagglutinin (HA) and neuraminidase (NA), which are crucial for its attachment to and release from host cells.
In humans, the flu virus commonly causes symptoms like fever, cough, sore throat, body aches, fatigue, and sometimes gastrointestinal issues. While most individuals recover within a few weeks, the flu can lead to severe complications, especially in vulnerable populations such as the elderly, young children, and individuals with weakened immune systems. These complications can include pneumonia, bronchitis, sinus or ear infections, and, in rare cases, even death.
Flu viruses are classified into types A, B, C, and D, with types A and B being the most prevalent in humans. Type A is responsible for major flu outbreaks and pandemics, as it can infect humans, birds, and some mammals, undergoing frequent genetic changes through a process known as antigenic shift. Type B primarily infects humans, though it evolves at a slower rate, leading to less severe outbreaks. Type C infects humans and mild respiratory symptoms, while type D primarily affects cattle.
To combat the flu virus, annual vaccination is recommended, as it provides immunity against the strains predicted to circulate during the upcoming flu season. Antiviral medications may also be prescribed for severe cases or individuals at high risk of complications.

Etymology of FLU VIRUS
The term "flu virus" is a compound word with two main components.
The first component, "flu", is an abbreviation for influenza. Influenza is derived from the Latin word "influentia", meaning "influence" or "a flowing in". The use of "influenza" to refer to an infectious disease caused by viruses is believed to have originated in Italy in the 18th century.
The second component, "virus", comes from the Latin word "virus", which originally meant "poison" or "venom". The term "virus" was used to describe noxious substances or liquids in ancient times. Over time, it came to be associated specifically with a disease-causing agent or infectious microorganism.
