Influenza

WHAT IS INFLUENZA?

Influenza, commonly known as the flu, is an infectious respiratory disease caused by influenza viruses that invade the respiratory system, affecting the nose, throat, and lungs. There are two primary categories of influenza viruses, designated as types A and B. Certain populations, such as individuals aged 65 and older, young children, and those with specific health conditions, face an increased risk of experiencing severe complications from the flu. Some of the symptoms include fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue.

The predominant mode of flu virus transmission involves small droplets generated when individuals with the flu cough, sneeze, or speak. These droplets have the potential to land in the mouths or noses of nearby individuals. Alternatively, a person may contract the flu by touching a surface or object carrying the flu virus and subsequently touching their own mouth, nose, or possibly their eyes.The primary way to prevent the flu is receiving an annual flu vaccine. In addition, adopting everyday preventive measures, such as avoiding contact with sick individuals, practicing proper cough and sneeze etiquette, and regular hand washing could mitigate the transmission of germs responsible for respiratory illnesses, including the flu.
