Effects and Symptoms of Influenza

There are 3 types of the Flu type A, B, and C. Type A occurs in animals, type B occurs in a widespread of humans. The causes of influenza effects are:


  • Fever over 100 F (38 C)

  • Aching muscles, especially in your back, arms and legs

  • Chills and sweats

  • Headache

  • Dry, countinous cough

  • Fatigue and weakness

  • Nasal congestion

  • Sore throat

How to Prevent Influenza

To protect yourself from influenza you should get seasonal flu vaccines. Also you should have good healthy habits like covering your mouth, washing your hands, all these things can help stop the virus and germs from spreading. Medicine such as Tamiflu, Relinza, and Oselivatumor are all types of medication that can help.

Immune Cells that work with Influenza

Chemokines, these cells attract immune cells to the site of the infection or virus which include macrophages, netrophills, and natural killer cells. These in turn make additional cytokines, chemokines and the process in the end attracts a number of immune cells in which at the end some are immune to the virus. The first line of defense is the innate immunity which is composed of mucus. TLR is the first to tell if there is a flu virus. When a cell first gets the virus so the innate molcules build a protection wall to slow down the virus, after this 2 signals the innate and adaptive. The innate stops the virus from replicating. The adaptive response sends out antibodies to stop the virus from spreading to the respiratory area. The T cell protects while tries to kill off the virus.

Treatment

Rest and fluid until all the virus is out of your system, Tylenol can help with the headaches and cough medicine. Antiviral medicines such as Tamiflu, Relinza, and Oselivatumor if it is a bad case of the flu. All these will affect by calming the flu down, and can end it a day early.

Causes and risk factors

All three types of the Flu are cause by the same way when a infected person leaves droplets by either coughing, sneezing, or putting their mouth on a object. The flu is a airborne virus. The risk factors age, immune systems weakens, pregnancy, heart problems, asthma, obesity.

How they replicate

Must first produce positive sense of mRNA to produce necessary enzymes. Once the enzymes translated are able to replicate, the final progency eventually bud from the host cell and the replication is taken place and ready to infect more.
