What exactly are they and how can they be prevented?

By Quin Anderson and John Cumpston

What is an infectious Disease?

Infectious diseases are diseases caused by microorganisms, such as viruses, bacteria, and parasites. These diseases are transmitted from one person to another through casual contact, such as influenza; through bodily fluids, such as the HIV virus, or via contaminated air, food, or water.

What is the "Superbug" MRSA?

MRSA, short for methicillin-resistant Staphylococcus aureus, is a bacteria that causes infections that can no longer be treated with common methicillin antibiotics and has become resistant. Its resistance against all methicillin and penicillin antibiotics makes it very difficult to treat causing 94,000 infections and killing 11,000 in the US every year. It is now common in hospitals and other healthcare areas by getting onto items that open wounds and end up infecting them. Bedbugs have also been carriers of the Bacteria. A genetic mutation has made the bacteria resistant to all forms of medication, making it a “Superbug,” which is any type of infectious disease that cannot be treated due to a mutation.

What is the difference between Bacteria, Viruses, and Parasites?

How are infectious diseases treated?

Antibiotics can be used to treat many infections however due to the diseases becoming immune to the antibiotics the use of antibiotics has become much less frequent and are only used when completely necessary. Now scientists and researchers are trying to find new ways and new drugs to treat the infectious diseases.

How can a person stay healthy enough to prevent infections and disease?

There are 27 diseases that can be prevented by vaccination. Washing your hands is one of the single most important ways of preventing the spread of disease and getting disease. Also, avoid being around people with diseases that can easily spread through touch, air, or feces. Eating healthy and exercising frequently is also just as important. Properly cooking food and boiling water to prevent bacteria is also a major way to prevent getting sick. Immunization projects have also killed off many infectious diseases such as polio and influenza in some countries.
