8.L.1.2-Explain the difference between a epidemic and a pandemic as it relates to spread and Prevention of disease


Microbiology is the study of micro organisms. people study it to learn how to prevent infection and disease or even to create medicine.


Bacteria is a living micro organism that is prototypical or unicellular. They can be spherical spiral, or rod like. They can use Celia or tail like flagella to move around. To fight it we can use anti bionics. An example of a bacterial infection is gangrene.


Fungi is a micro organism that gets nutrients by decomposing. Fungi can be mushrooms, in which have spores. Fungi can help us and pit is in danger. An example of a dangerous disease caused by fungi is fungal meningitis.


A virus is a no living micro organism that needs a living host cell in order to reproduce. Binary fission is what bacteria uses to reproduce. An example of a virus is influenza or the flu. To prevent viruses we use vaccines. But viruses can involve so each year we need a new one.


A parasite is a nonliving micro organism that lives on or inside something to take its nutrients. An example of one is a tapeworm. To prevent a lot of parasite wash your hands after playing in soil if you still do that anyway.


An outbreak is when there is a bigger amount of people infected by people than expected. like if a whole town got a certain infection.


An epidemic is when a outbreak grows throughout one larger area like a state or country. an example of one is the Ebola epidemic last year.


A pandemic is when a infectious disease spreads throughout the whole globe or a very large part of it. To prevent these, or to stop them for getting worse stop all air travel and make quarantines for those expected to be sick, and for those who are.


The differences between a pandemic and a epidemic is the size of the area the epidemic, or pandemic is in. Usually a pandemic is more severe than a epidemic.



Outbreak-An occurrence of a disease greater than would be expected in a particular time or area.

Epidemic-A outbreak of a disease that effects many people in a specific country or region.

Pandemic-A epidemic that spreads over a very large area, or throughout the entire world.

Vector-An organism,typically an insect that transits disease.

Pathogen-A virus, bacteria, fungi, or parasite that can cause illness or infection.

Protozoa-Diverse organisms that cannot be classed as plants, animals or fungi.

Virus-A non-living pathogen that can change, and mutate. It infects a host cell and replicates to cause illness and disease.

Bacteria-Single celled prokaryotes that can cause disease. Multiply rapidly and can form colonies.

Parasite-An organism that lives in or on another organism called a host taking nutrients and often harming it in the process.

Fungi-A single-celled or multi cellular organism that can decompose or absorb organic matter. (Ex.mushrooms)

Host cell-A cell a virus invades, takes over, and and makes copies of itself.

Quarantine-A time or place
