INFLUENZA VIRUS Meaning and
Definition
-
The influenza virus refers to a family of RNA viruses that are the causative agents of the infectious disease known as influenza, commonly referred to as the flu. It belongs to the Orthomyxoviridae family and is classified into three types: A, B, and C. These types are distinguished by the specific proteins found on their surface, namely hemagglutinin (HA) and neuraminidase (NA). These viral proteins allow the virus to enter target cells and assist in the release of newly formed viral particles from the host cell.
Influenza viruses primarily infect the respiratory tract, causing a range of symptoms that can vary from mild to severe. Such symptoms commonly include fever, cough, sore throat, nasal congestion, muscle aches, fatigue, and headaches. In severe cases, especially in vulnerable populations such as infants, elderly individuals, those with weakened immune systems, or those with underlying health conditions, the flu can sometimes lead to complications like pneumonia or exacerbation of pre-existing conditions.
The influenza virus is highly contagious and spreads easily from person to person through droplets produced when an infected individual coughs, sneezes, or talks. It can also survive on surfaces and be transmitted by touching contaminated objects and subsequently touching the face or mouth.
Annual vaccinations are available to prevent influenza, although their effectiveness can vary due to the ever-changing nature of the virus. Additionally, antiviral medications can be prescribed to help reduce the severity and duration of symptoms if taken early in the illness. Steadfast hygiene practices, such as frequent hand washing and covering the mouth when coughing or sneezing, can also significantly reduce the spread of the influenza virus.

Etymology of INFLUENZA VIRUS
The word "influenza" originates from Italian, where it initially referred to the astrological influence of the stars and planets on human lives. It was believed that the illness was caused by the influence of these celestial bodies. The word itself comes from the Latin word "influentia", meaning "influence" or "flowing in". The term "virus" has its roots in Latin, where it means "poison" or "slimy liquid". Over time, the term "virus" has been used to refer to various harmful microorganisms, including the influenza virus. Consequently, the term "influenza virus" combines these elements, referring to the concept of a viral infection caused by the influence of external factors.
