Detailed explanation-1: -Viruses cause infections by entering and multiplying inside the host’s healthy cells. It can be difficult to know what causes an infection, because viral and bacterial infections can cause similar symptoms. Antibiotics won’t work for viral infections.
Detailed explanation-2: -On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
Detailed explanation-3: -Antibiotic medicines kill or keep many bacteria from growing but don’t treat viruses. Antiviral medicines help the body clear out some viruses.
Detailed explanation-4: -But what is the difference between these two types of germs? Bacteria are single cells that can multiply and cause infection. Viruses are much smaller than bacteria and need a host cell to reproduce. Viruses can only infect living cells, while bacteria can also infect non-living things like soil or water.
