Spread of Influenza Overview

Virus particles are released into the air through coughing and sneezing of persons who are ill with influenza. or when a person touches droplets, nose drainage or saliva from an infected person, or a soiled object, and then touches one’s own (or someone else’s) nose or mouth before washing hands. Crowded conditions in enclosed spaces provide ideal conditions for the spread of influenza.
 * 1. Influenza is primarily spread from person to person through the air**

A person can spread influenza starting one day before he or she feels sick. Adults can continue to pass the influenza virus to others for another three to seven days after symptoms start. Children can pass the virus for longer than seven days. Symptoms start one to four days after the virus enters the body. Some persons can be infected with the influenza virus but have no symptoms. During this time, those persons can still spread the virus to others.
 * 2. Contagiousness:**

Influenza is caused by a virus—a tiny particle that consists of RNA (genetic material also known as ribonucleic acid) inside a protein coat. The influenza virus, like other viruses, can only reproduce by taking over a "host" cell (a cell that provides nourishment for the virus).
