Can a viruses be cured using antibiotics?

Yes. But only by antiviral antibiotics, not antibacterial or antifungal or antiprotozoal antibiotics. Most antibiotics are antibacterial: such as penicillin, sulfa, cipro, rocephin, etc. The Herpes Simplex virus is a virus that can be attacked by an antibiotic, such as acyclovir. Just as with antibacterial antibiotics, antiviral antibiotics will become less effective over time as the viruses mutate to become more resistant. Therefore, these antibiotics should be used as judiciously as the other types of antibiotics.
