Detailed explanation-1: -Antibiotics are used to treat or prevent some types of bacterial infection. They kill bacteria or prevent them from reproducing and spreading. Antibiotics aren’t effective against viral infections. This includes the common cold, flu, most coughs and sore throats.

Detailed explanation-2: -Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.

Detailed explanation-3: -Antibiotics work by destroying the cell wall of bacteria or targeting the machinery of the growth of bacteria. Antibiotics are used against bacterial infection and cannot kill viruses. The mode of replication and structure of viruses are different from that of bacteria.

Detailed explanation-4: -Antibiotics damage the cell wall of living organisms leading to their death. The viruses do not have a cell wall. Antibiotics are produced by bacteria and fungi that treat bacterial infections, not viral infections because viruses use host cells to perform their activities. So, they cannot kill viruses.
