Major Symptoms

One Major Symptom is Feverish feeling, and aches, which include. Cough, Sore throat, Runny or stuffy nose, Muscle aches, headaches, Fatigue, and sometimes diarrhea and vomit which is more common in children than adults.

Causes of the virus

Since Influenza is contagious it travels from person to person. Influenza is spread in droplets through the air when an infected person coughs, sneezes, or talks. You can either inhale the droplets or you can put these germs on your eyes, nose, or mouth with your hand.

Immune cells involved in immune response

Some immune cells involved in immune response are macrophages, mast cells, Natural Killer cells, neutrophils, eosinophils, and basophils.

How influenza replcates

Influenza replicates by binding to the outside of the cell. It is engulfed by the cell, and once inside the membrane, the virus releases it's RNA. Then the virus starts viral RNA replication and protein synthesis. Lastly the virus assembles in the host cell and initiates the lytic cycle after previously being in the lysogenic cycle, resulting with the death of the cell and a release of the virus.

How can influenza be Treated?

Influenza can be treated with an antiviral drug, which could be in the form of a pill, liquid, an inhaled powder, and intravenous solution. These are usually pre-made antibodies which cost more than vaccines, because in vaccines your body is given an antigen so your body then makes the antibody.

Prevention

You can prevent yourself from getting the flu virus, by taking yearly vaccines. Vaccines usually take about 2 weeks to start producing an antibody. There are many different types of flu shots you can take, which categorize by how old you are what you are allergic to, and the cost.
