Find Out the Difference Between Bacterial, Parasitic, And Viral Infections

There are many things that can contribute to the same symptoms. Common symptoms in a health condition include sore throat, chills, and achy muscles. But how are you supposed to know how to treat your symptoms if you are unaware of the cause? The conditions that can cause similar symptoms are all different in how they affect the body and how they are abolished. Here are the differences between viral, bacterial, and parasitic infections.



Viruses only exist to replicate. They are very small, in fact, they are the smallest proxy of infectious disease. Most viruses are round and are approximately 20 – 200 nanometers in diameter. Viruses are essentially a very small piece of genetic material that is surrounded with a thin coating of protein coating. Viruses may also contain a small amount of fat. They can be found in soil, water, and sir.

Viruses, unlike other infectious microorganisms, cannot reproduce outside of a host cell. Viruses do not consume food, but rather absorb the energy and materials from their host cells. Viruses are able to infect almost every kind of organism, some even infecting bacteria and fungi.

Some viral diseases are Norovirus and Hepatitis A.


Bacteria are much larger than viruses, measuring ten to 100 times as large. Typically one to three microns long, they are rod or sphere shaped. Most bacteria usually inside of a fatty membrane and consist of DNA and cellular machinery.

Some bacteria are actually beneficial and aid in the body’s processes such as digestion. They can also break down sewage and are added to certain foods such as yogurt. However, when a bacteria becomes spoiled, it affects the smell, texture, and taste of a food.

Bacteria gain energy from the same sources that people do, including protein, sugars, and fats. Bacteria need a low pH, time, nutrients, oxygen, and water to grow. They also need to be at a growing temperature between 41 degrees F and 140 degrees F. While some bacteria are able to live and reproduce in their environment (such as food), others are able to adjust to life within a host. Bacteria can be so fast-growing that it quadruples in number every half hour, while other strains of bacteria take weeks or even months to reproduce.
