Children frequently catch the common cold and for parents, repeated cases can become difficult to deal with. Usually we treat colds with over-the-counter medications, but many parents wonder about suitable antibiotic treatments for this common ailment. Antibiotics were first used to treat disease, viruses and bacteria during the 1940s and they have been very productive and have saved many lives over the years. Before we can address the suitability for antibiotics as a tool against the common cold, we need to understand how viruses and bacteria function.
Viruses are almost immeasurably small. We use a scale of a billionth of a meter to measure their size and discover that most are from 20 nanometers to 250 nanometers long. They can only exist and reproduce in living cells, and once in a living cell they begin to produce virus particles. If viruses were the size of a mouse, humans would be the size of a large brontosaurus.
