how many viruses human body

How many viruses does a human being have?

If you think you don’t have viruses in our body because you are not sick you are totally wrong because many viruses chronically infect us without inducing any disease.

The viruses living in and on the human body is known as the human virome and may infect both human cells or the bacteria found in our body (bacteriophages).

The human virome is far from being completed but recent methods, including next generation sequencing, estimated that 380 trillion viruses live in the human body.

…but how many zeros are there in a trillion?

This is a very good question, 380 trillion have 12 zeros:

380,000,000,000,000

However, this number is not fixed, the human virome composition varies with different factors, including other components of the microbiota (specifically bacteria), age or diet.
