There are only a few basic ways to fight viruses. A vaccine can prime the immune system to attack them as soon as they invade the body. If a virus manages to establish itself, a doctor may be able to prescribe a drug to slow down its spread. And if all else fails, a doctor may quarantine a patient to head off an epidemic.
Now some scientists are exploring a fundamentally different strategy to fight viruses. They want to wipe them out by luring them to their destruction, like mice to mousetraps.
