How Influenza Affects the Human Body – What You Should Know | Respiratory System | Viruses

[The Epoch Times, January 21, 2022](Written by Sara Novak/Compiled by Zhizhuo Qu of The Epoch Times) The flu season runs from October to May and affects millions of Americans every year. The flu virus attacks the respiratory system, with symptoms including headache, sore throat, fever, chills, vomiting, dry cough and muscle aches. But what does it do to your body? What does your body look like during the flu?

A sick person sneezes, coughs, or simply expels thousands of droplets of the flu virus, and for the unfortunate victim, inhaling them into the nose can signal the start of an infection. Influenza viruses can embed within the cells of the airways, and when a cold hits your nose and throat, the flu virus spreads to your lungs.

The outside of each virus has what amounts to keys, and if those keys fit into the locks on the cell’s surface, it can enter the cell. Once inside the cell, the virus starts to multiply, starting with one virus and multiplying into millions.

Your immune system kicks in, producing millions of T cells to destroy the virus. This eliminates the virus inside the cell, but in some cases the cell may burst, sending the virus elsewhere throughout the body. At this point, you are contagious.

By around day 4, you start to experience symptoms such as fever, chills, and headache. It’s not the flu virus that makes you feel these symptoms, but your body’s response to it — inflammation. All of your body’s energy is also used by your immune system to fight the flu. (Note: Inflammation is a protective immune response of the immune system to the body.)

After about a week, your body will be able to control the flu and the inflammation will slowly decrease. At this point, you’re still contagious, at least for a few more days. To stop the spread of the virus, be vigilant and wash your hands with soap and warm water.

Most people start to feel better after about a week. However, if your flu symptoms seem to get worse rather than better, or if you have trouble breathing or have other complications such as a sinus infection, you should see your doctor. Also consider seeing your doctor if you have other medical conditions, such as diabetes, heart disease, asthma, or other lung problems.
