People who are infected and develop COVID-19 can receive supportive medical care from their doctors to help relieve symptoms. Treatment may include antiviral medication or monoclonal antibody infusion, if available. Antibiotics don't prevent or treat coronavirus. Antibiotics can only treat bacterial infections, and COVID-19 is caused by a virus. Some COVID-19 patients may also develop a bacterial infection, in which case their doctor may prescribe an antibiotic, but the medicine will not treat the coronavirus itself.
