How Do Antibiotics Work?
Antibacterials aren’t the answer for every infection your child gets. In fact, there are 2 major types of germs that cause most infections, viruses and bacteria, and antibacterials are useful only against bacteria.
Bacteria are one-celled organisms that are just a few thousandths of a millimeter in size. They live on our skin, in our digestive system, and in our mouths and throats. In fact, there are one hundred thousand billion bacteria living and thriving on or inside of us. Although most are either harmless or actually serve a positive role in the body (eg, helping to break down the nutrients in our diet), some are dangerous and cause illnesses. They’re responsible for many childhood diseases, including most ear infections, strep throat, some sinus infections, and urinary tract infections.
Viruses are even smaller than bacteria. The poliovirus, for example, is only 16 millionths of a millimeter in diameter. Despite their size, viruses can cause mild and serious diseases when they enter healthy cells in the body. They’re responsible for the common cold, the flu, and most sore throats and coughs. They also cause smallpox, the measles, the mumps, hepatitis, and acquired immunodeficiency syndrome (AIDS). As powerful as antibacterials are when used in the right situations, they cannot kill viruses and do not work against viral infections. If they’re given to your child when she has a viral infection, they can not only cause side effects, but also add to the serious problem of antibiotic resistance. There are drugs called antivirals that have been developed to fight viruses.
