Which is bigger virus or bacteria?

Viruses are much smaller. The largest of them are smaller than the smallest bacteria. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.

Is a virus smaller than bacteria?

Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can’t survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.

Can you get rid of a virus in your body?

But it will increase your chances of getting side effects, such as pain in your stomach, diarrhoea, and feeling or being sick.

What happens if you take antibiotics when you don’t need them?
