Detailed explanation-1: -The flu is caused by an influenza virus. Most people get the flu when they breathe in tiny airborne droplets from the coughs or sneezes of someone who has the flu. You can also catch the flu if you touch something with the virus on it, and then touch your mouth, nose, or eyes. People often confuse colds and flu.
Detailed explanation-2: -When fighting an influenza infection, the body may raise its temperature to make it difficult for the virus to replicate. This abnormal increase in body temperature is known as a fever. A fever is part of the immune system’s response to an infection and is a typical flu symptom.
Detailed explanation-3: -Once in your nose, the virus sets up residence, infecting the cells in your nasal passageways and airways. The virus enters a cell and replicates, making daughter viruses (aka copies of itself) that then go and infect more cells nearby. This continues until more and more of your cells are infected.
