Summary
Antibiotics treat bacterial infections but do not work against viruses.
In depth
Bacteria are cells; they can be treated with antibiotics, which target bacterial structures. Viruses require host cells, so antivirals target viral enzymes (such as oseltamivir for influenza). Misusing antibiotics for colds promotes resistance.
Diagnosis uses culture, PCR and antigen tests. Treatment differs; antiviral options are fewer. Viral infections can be followed by bacterial secondary infections.
Common mistake: green mucus does not prove bacterial infection.
