For instance, how the virus gets into the cell is still unknown.

Nobody seems to know just how the virus got here.

I was hoping the virus would get in his mouth.

Why a manufactured virus when we've got the real thing to make us sick, or worse?

The virus was getting to his mind now, making him feel like a super hero.

Researchers couldn't figure out how the virus was getting to humans.

"And the virus got almost everyone but the group it was built to kill."

I have no desire to see another virus get loose in this station.

This means most viruses can only get inside these cells by force.

The damage done to cell walls would let the virus get in.
