Question

Explain why antibiotics are ineffective against viruses.

Answer 1

... Antibiotics are only affects Bacterias, Virus are a much smaller and anatomically diffrent structure.
The name Antibiotics auctally hints it's properties. "Anti-Bacteria".

Answer 2

Depending on the type of antibiotic, it may attack the bacteria's cell membrane, interfere with the function of its organelles (particularly mitochondria) or prevent it from replicating.

Viruses are basically just bundles of DNA. They are not living, and the only way they can reproduce is by hijacking healthy cells and forcing them to replicate the viruses' DNA. The reason antibiotics don't work with viruses is the same reason poison gas doesn't hurt a machine. You cannot kill something that isn't alive.

Answer 3

Just to expand on the answers above, the term antibiotic is usually synonymous with anti-bacterial, but the word itself means "anti-life" (from "bios", the Greek word for life; "biology" is the study of life) and can be used as an umbrella term that includes anti-fungal agents.

Antivirals, however, do NOT qualify as antibiotics: as byssine said, viruses are not technically alive. Some scientists disagree, but the general consensus is that they are non-living bits of rogue DNA or RNA, or at best fall into a grey area. They can be destroyed, but a drug that's designed to target or interfere with components of a living cell just isn't going to touch them.

Answer 4

Virus dont have theire own machnery, they are kind of parsitic

Antibiotics blocks vital process so ineffective against virus
