Viruses Versus Bacteria: Key Differences and Their Impact on Health

The video explains the differences between bacteria and viruses, highlighting their characteristics, structures, and roles in infections. It discusses how viruses are submicroscopic agents that require a host to reproduce, while bacteria are larger, diverse microorganisms found everywhere. The video also covers treatment and prevention methods, noting that viruses are hard to treat and often require symptom management or vaccination, whereas bacterial infections can be treated with antibiotics. The importance of responsible antibiotic use to prevent resistance is emphasized.
