This virus used to kill people, cause blindness, and bad scars.

Some viruses use something called polymorphic code to change their signature every time they move.

The virus commonly uses these methods to be passed from one host to another.

I'm more than happy for you to suggest improvements but the two genetically engineered viruses I've been using are line.

Once within the host, the virus uses the host to replicate.

Instead a virus uses the machinery of the host cell to make copies of itself.

We skimmed a little blood, used a virus they didn't like.

There is some evidence the mineral may prevent the formation of certain proteins that cold viruses use to reproduce themselves.

The dead virus, or parts of it, used in a vaccine raise immune responses without causing the disease.

The virus mutated and uses the report as a medium.
