What is a virus? Viruses have no cellular structure and are obligate intracellular parasites. They can only multiply inside the living cells of animals, plants, or other microbes. Familiar viruses include herpes, Influenza, HIV, HBV, HCV, Varicella Cytomegalo virus, respiratory synciitial virus, rotovirus, and noro-like viruses. These viruses will not be eliminated by the use of antibiotics. Colds and some ear and most sinus infections are caused by viruses, not always bacteria. Bacteria cause illnesses like strep throat that are often treated successfully with antibiotics (CDC).
Taking antibiotics to treat a virus can make those drugs less effective when you and your family really need them. Limiting the usage of antibiotics will also help limit new cases of C. diff. infections.
* Please note that each individual case/diagnosis varies with each patient and the use of antibiotics for treatment will be determined by the healthcare professional and treat the diagnosis.
