Bacteria are typically much larger than viruses and can be viewed under a light microscope. Viruses are about 1,000 times smaller than bacteria and are visible under an electron microscope. Bacteria are single-celled organisms that reproduce asexually independently of other organisms. Viruses require the aid of a living cell in order to reproduce.

As the names suggest, bacteria cause bacterial infections, and viruses cause viral infections. It is important to know whether bacteria or viruses cause an infection, because the treatments differ. Examples of bacterial infections include whooping cough, strep throat, ear infection and urinary tract infection (uti).

Flu season can hit hard, causing you to take time off from work or school while you spend time recovering from your symptoms. Even if you get the latest vaccine, you can still come down with the flu particularly during autumn and winter.
The virus may remain silent or undergo productive infection without seriously harming or killing the host. Mechanisms of persistent infection may involve the regulation of the viral or host gene expressions or the alteration of the host immune response. The two primary categories of persistent infections are latent infection and chronic infection.
The four major types of germs are bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people, and sometimes they can make us sick. Bacteria (say: bak-teer-ee-uh) are tiny, one-celled creatures that get nutrients from their environments in order to live.

They live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself.
Immunisation is available to prevent many important bacterial diseases. A virus is an even smaller micro-organism that can only reproduce inside a host’s living cell. That’s why some of the most serious communicable diseases known to medical science are viral in origin.
