It's going to get busy from here.

Huh?

I was wondering if we'd need it, but I'm glad I kept that cowpox in storage.

We'll start by vaccinating the people who came with him.

Ah, of course!

Smallpox is extremely contagious.

We need to treat at least the patient's family, friends and neighbors.

But where did he catch it in the first place...?

We might need more manpower to help us with this.

Whoa... Is it really that serious?
