So you know how when you get sick with a cold or flu, your body tries to fight off the germs that made you sick?
Well, sometimes viruses (which are the germs that make you sick) are really good at getting past your body's defenses. They can make you feel really sick and make it harder for your body to fight them off.
That's where virokines come in! They are things that some viruses make to help them survive and spread more easily. Virokines can do different things depending on the virus, but some ways they help the virus are by slowing down your immune system or making it harder for your body to recognize and attack the virus.
Scientists are studying virokines to try to find ways to stop them so your body can fight off viruses more easily.
