The first type is Active Immunization, that means that a person is expose to the microbes and their immune system fights back. There are two types of active immunizations the first one is naturally acquire, that is when a person has contact with a pathogen and then the person gets sick but their body recovers. Their body then knows how to deal with that pathogen and they are able to fight it off, we can be immune to those pathogens for lifelong for example measles. The second type is artificially acquire, that is using vaccines to fight pathogens. The second type of immunization is Passive Immunization, which means that immunity is pass from one person to another. Just as Active Immunization, passive immunization can be naturally acquire, which means that the immunity is pass from the mother to the child by the mother breast feeding the child or when the mother’s placenta is crossed to her fetus. Artificially acquire Immunization means that vaccines are injected to a person, and the vaccines contain antibodies that are from animals that are already resistant to the disease. The down side about passive immunities is that the human body may reject the antibodies. Also the immunization may only be effective for a couple of …show more content…
A reservoir can be a human, an animal or the environment. Any human body it’s able to carry any disease. For example gonorrhea. Animals can also harbor pathogens for example rabies. The environment is another place where pathogens can live, for example soil, water, dust, carpet and other places. One bacteria that lives in the environment is vibrio cholera. The second thing is to leave the reservoir and enter a host. This can be done from human to human. For example sneezing, coughing. Direct contact is another human to human way to transmit a disease. For example shaking hands or hugging and kissing. When a mother passes the infection to their child is called vertical transmission. Airborne is another way to transmit a pathogen. The pathogen can travel a great distance and attach to other things that’s what makes it easy to transfer. Pathogens can also travel thru air, for example tuberculosis. Vehicle is another way to transmit a pathogen, They can use food, water and foam to transfer pathogens. For example they can be transmitted by humans touch a keyboard, a pencil or other objects. Parenteral is another way that a pathogen can leave the reservoir. This can be something that breaks the skin, for example a mosquito bite or an unsterilized needle. The last way to transmit a pathogen is by vectors, which include biological vectors, and example is when a fly picks up microbes and carries to your food. The
