Bacteria are free-living cells that can dwell inside or outside the body, whereas viruses are non-living chemical collections that require a host to survive.
Viruses are smaller than bacteria, with the largest viruses being smaller than the tiniest bacteria. They only have a protein coat and an RNA or DNA-based genetic material core. Viruses, unlike bacteria, require a host to survive. Only by attaching themselves to cells can they multiply. You can submit a guest post health category to share your views on the same.
