What is the difference between viral parasitic and bacterial infections?
Bacteria and viruses can live outside of the human body (for instance, on a countertop) sometimes for many hours or days. Parasites, however, require a living host in order to survive. Bacteria and parasites can usually be destroyed with antibiotics. On the other hand, antibiotics cannot kill viruses.
Is a parasite a virus or bacteria?
Parasites are part of a large group of organisms called eukaryotes. Parasites are different from bacteria or viruses because their cells share many features with human cells including a defined nucleus. Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.
What are viruses and bacteria called?
The term “germs” refers to the microscopic bacteria, viruses, fungi, and protozoa that can cause disease. Washing hands well and often is the best way to prevent germs from leading to infections and sickness.
What are bacterial infections?

Viral infections are treated with antiviral medication.
What type of organism is a parasite?

Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.
What is the difference between parasites and fungi?
Fungi are eukaryotes, meaning that like parasites, their cells have a true nucleus and complex internal structures. They are most commonly found as environmentally resistant spores and molds, but can cause disease in humans in the form of yeasts. Fungi most often cause skin infections and pneumonia.
