When most people think of treating infections, they think of antibiotics. But antibiotics
only work against bacterial infections.
Viral Infections
Most common infections, like colds and flu, are viral
and antibiotics have no effect on viruses. Most coughs, sinus problems, ear infections, sore
throats and other common contagious diseases are viral in nature, it's a waste of time
and money to treat them with antibiotics.
Viruses don't just cause colds and flu. Chicken pox, mumps and measles are all acute
viral infections. There are also chronic viral infections like herpes and more serious and
dangerous viral infections such as smallpox, hepatitis C. Epstein Barr, SARS, AIDS and
Ebola.
The reason serious viral infections raise concerns is because modern medicine has very
few effective antiviral drugs. Most drugs only relieve the symptoms of viral infections. So,
when it comes to viral infections modern medicine focuses its efforts primarily on trying
to create immunity to them through vaccines.

Understanding Viruses
It is important to understand that a virus is very different than a bacteria or fungus. A
bacteria, fungus or yeast (like Candida albicans) is a single celled organism. It feeds and
grows, then divides to reproduce. However, viruses are not cells! They are pieces of DNA or
RNA wrapped in a protein coat, having none of the structures or processes that cells have.
So, there is some debate about whether viruses are alive or not.
That is because
outside of a living cell, a virus is inert. In order to replicate itself, a virus must enter a living cell and hijack cellular mechanisms that make copies of the DNA
or RNA. So, a virus has no "life" outside of another cell. It doesn't grow or metabolize
nutrients or perform other functions that cellular organisms do. This means you cannot"kill" viruses in the way one can kill a bacteria or fungal cell.
How the Body Deals with Viruses
Your body combats viruses in several ways. First, the innate immune system, found
primarily in the membranes of the digestive and respiratory system is designed to destroy
foreign material (like viruses) to prevent them from ever entering the body. So, a healthy
intestinal and respiratory system forms a protective barrier against most viral infections.
If a virus is able to get past the in innate immune system, then the adaptive immune system
takes over. It produces substances called antibodies that attach themselves to a virus and
render it inert so it cannot enter cells and disrupt their normal functions.
