Source of pathogens



Influenza originated in Southeast Asia from the birds and other animals such as pigs.Influenza gets in the body and move through the respiratory tract.The virus will start to binds to the surfaces of the cell.Influenza takes and brings out genetic information into the cell's nucleus. The virus reduplicates and takes over cell functions.Influenza will move into the cell membrane and the cells will finally die. Releasing the virus into the body, it will infect the body causing inflammatory in the respiratory system.Influenza will effect the respiratory system such as the nose, throat, lungs and bronchial tubes.

The transmissions is the respiratory tract. Portal of entry is the Droplet transmission, Direct contract, Indirect contract and the vehicle.

DAY 1 ) The virus enters the body by the nose or mouth.

DAY 2-4) The virus will settle in your lungs to grow.

DAY 5) Influenza symptoms will start such as temperature rise, body aches , tingling skin, heavy cough and sore throat.

DAY 6-9) Your immune system is already under the Influenza

DAY 10-14) Your body will produce antibodies to destroy the virus. "Recovery phase"

Non-Specific defense

The innate inhibitors in respiratory provide an initial barrier to infection. Dendritic cells and phagocytes, natural killer cells help promote further innate and adaptive responses. Cytoplasmic RNA sensors are activating these responses. The innate immunity can indicate the host functions that directly in the genome. Also they can be capable of recognizing, transformed host cells. The first line of defense against infection can innate immunity to promote and direct the immune response.


1)Fever over 100F


3)Sore throat

4)Nasal congestion

5) Coughing

Specific Defense

Influenza enters the body and attaches to B cells receptors that create antibodies. The B cells receptors bind to the virus particles and help reduce the virus spread. B cells sends information and the antibodies go where they can fight off the virus.The T(helper) cell ultimately determine (with the antibodies) that capacity of the host to eliminate the virus.The organs affected will be the lungs being inflamed.

Special Characteristics

The flu vaccine, the antibodies will provide protection against infection in your body with the viruses that are in the vaccine. Your antibodies will balance out the virus and help kill the influenza infection in your body.

Interesting information

1) Influenza highest spread is in February

2)Influenza is mostly used as the word "Flu"

3)5-7 days to become contagious from Influenza
