Viruses and bacteria are tiny organisms that can cause diseases, but they are very different. Bacteria are living cells that can grow and reproduce on their own, while viruses are much smaller and need to infect a host cell to multiply. Some bacteria are helpful, like those in our gut that aid digestion, but viruses are always harmful and cause infections like the flu or the common cold.
Treating bacterial infections usually involves antibiotics, which kill bacteria or stop their growth. However, antibiotics do not work against viruses. Instead, viral infections often need rest, fluids, and sometimes antiviral medications. Understanding the difference helps doctors choose the right treatment and prevents the misuse of antibiotics.
