How does antibiotics fight a cold?
Antibiotics work against bacterial infections only. They either prevent the bacteria from multiplying or they affect the cell contents of the bacteria and stop the bacteria from constructing their cell wall. However, antibiotics won't work against cold because common cold is caused by a virus. Since virus contains only RNA and is non-living outside host cell, i.e.,there is no cell wall in viruses. so, antibiotics do not work against them. Therefore, it is not advisable to have antibiotics to fight off a cold.
