According to research from the World Health Organization, peoples’ misunderstanding of antibiotics is contributing to the increase in drug-resistant infections. A survey released by the WHO revealed that 64 percent of participants incorrectly believed that antibiotics could be used to treat colds and the flu. Most of these infections are caused by viruses and do not respond to antibiotic therapy. Additionally, a third of people surveyed believed that they should stop taking antibiotics when they feel better instead of completing the entire treatment course as prescribed. If your doctor prescribes an antibiotic for your bacterial infection, finish the complete course to prevent a relapse.
