Question

why are medicines more effective against bacterial infections than viral infections?

Answer 1

medicines work effective on bacterial infection because the bacteria can easily be detected but it is difficult to detect a virus in the body.

the bacteria are living organisms so the antibiotics easily find them and kill them in the body.

the virus act living when they are in contact with human cell (otherwise non living properties are shown) so it is difficult to detect a virus in the body.

Answer 2

⇒ Antibiotics are commonly use to block biochemical pathways which is important for bacteria.

⇒ Many Bacteria make cell wall to protect themselves.

⇒ The antibiotic penicillin blocks the bacterial processes that build the cell wall.

⇒ As a result, The growing bacteria are unable to make cell wall and die easily.

⇒ But viruses do not use this path ways therefore antibiotic do not work against viral infection.
