Influenza/ FluBy Will

General information

In 1918 a major pandemic occurred world wide

Veterinarian J.S. Koen discovered Influenza in 1918 after seeing the same virus in a pig as the virus in spain

This pandemic killed 50 million, and almost 40% of the world’s population was infected with Influenza

This Pandemic lasted a year, until everybody was immune, or dead.

The Host

The virus is breathed in through the patient's nose and mouth. It then goes down into the throat where the bristles on the virus’s surface latch on to a healthy cell then the unknowing cell takes the virus in and reproduces virus. After the virus leaves the cell the cell dies. The virus keeps on doing this until the immune system defeats it or the patient dies. When the Flu gets worse it weakens the lungs making it an easier target for Pneumonia to invade. More often than not the patient dies from Pneumonia than the Flu.

Take medicine such as Ibuprofen

Did you know that the flu shot is made up of three to four dead viruses to stimulate your body being attacked by a virus, so that your immune system will build up an immunity to it

The Pathogenic Agent

Influenza is a virus

Because influenza is a virus, it does not have cells

A single virus looks like a round ball with knobby keys

It reproduces by going into a healthy throat cell and going into the nucleus. There the virus is copied by a molecule and sent out.

This virus is spread through the air, most often when an infected person talks, sneezes, or coughs. This viruses would travel through through droplets of spit, or mucus

The Pathogenic Agent… continued

To kill the virus the immune system employs its adaptive immunity. The adaptive immunity is made up of two cells, B cells, and T cells. T cells are like the front line fighters when it comes to fighting virus. b cells develop immunities to viruses so you can not get them again.T cells have three jobs, number one, kill infected cells with a protein on the surface of the cell called CD8, number two, activate B cells to make an immunity to is so the next time the virus comes into the body the immune system will be able to kill it easily, and number three, activate other virus fighting cells.

The Environment

Influenza season is from october to may for the northern hemisphere, and April to September, however in tropical countries the flu can be spread all year long.

Did you know that you can go to any place in the world and not have an increased risk of getting the flu, however it is possible if you go to tropical or southern hemisphere countries you could get the flu outside of the normal flu season for the US.

Influenza Fun Facts

Did you know that the reason you have to get flu shots every year is because the flu virus each year is different than past years.

Over 200,000 people each year are put in hospitals because of the flu.

Around 49,000 people die from the flu each year

People over 65 should get a stronger flu shot because as you get older your immune system gets weaker, as you get older.

Did you know that in the common flu shot there are three different types of influenza strains.

Influenza affects more than 5% of the US population each year

Did you know that there is a vaccine in the form of a nasal spray! This comes in handy if you’re really afraid of needles (like me).
