This can also be cured due to the pathogens within a human body. The pathogens can fight the bacteria cells and remember them so that if the same cells enter the body the pathogens can fight the cells. Pathogens are a defence for the human body without it the human body will not be able to fight the bacteria cells.
Bacteria sources of infections
Modes of transmissions
- Contact, by a mammal or insect; will have to have a contact with the person.
Methods of entry in the human Body
- Bites from mammals to insects
- Dust from the air
- Contamination of water which is dirty
- Cuts on the human body which can let in bacteria.
Virus
Viruses are too small to be seen by the eye on its own (naked eye) They can't multiply on their own, so they have to invade a cell and take it over in order to be able to make more virus particles.
Viruses consist of genetic materials usually DNA; surrounded by a protective coat of protein. The cells of the mucous membranes, such as those lining the respiratory passages that we breathe through, are particularly open to virus attacks because they are not covered by protective skin.
Virus sources of infections
Modes of transmission
- Droplets, can spread by another person coughing, sneezing or a direct talk with the person.
Methods of entry in the human body
- A person with a cold can spread the infection by coughing or sneezing.
- Viruses can be passed on by touching or shaking hands with another person.
- Body fluids such as blood, saliva and semen can contain the infecting organisms for example by injection or sexual contact, is important, particularly for viral infections like hepatitis or AIDS.
Fungi (Fungus)
Can spread through the spores; the spores enter the human body if the body is not in its correct condition. For example cuts can let in spores.
The damper and darker it is the more it spreads within a human body. Its dark and very wet as well as the warmth is just right for the spores to develop.
Animal has flakes within their skin when there is a direct contact fungi can get within the skin and cause an infection
Source of infection
Modes of transmissions
-
Direct contact – with an infected person, animal or soil.
Methods of entry in to the human body
- Mainly against skin; soil.
- Contact with an animal that is carrying fungi spores.
- Contamination of fungi.
- Cuts can let in spores which creates fungi infections.
- Walking bare feet in a swimming pool, shower area or a sauna.
