A Epidemic is the same thing but it affects a country or region and has bigger amount of sick people than a Outbreak would have like Ebola it is in the region

A Pandemic is the same thing as a outbreak but it affects people worldwide and is bigger than a Epidemic and it would have more sick people than a epidemic



Virus-A virus is a small infectious agent that replicates only inside the host cells of other organisms. viruses can infect all types of life forms.

Bacteria-Bacteria constitute a large domain of prokaryotic microorganisms bacteria have come in shapes, ranging from spheres to rods and spirals. and they can be good or bad.

Fungi- Fungi is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds

Parasite-an organism that lives in or on another organism and benefits by sucking the nutrients at the host's expense.

Eukaryotic-A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes
