The good virus

Not all viruses are out to get us - in fact, the viruses that do us harm are vastly outnumbered by viruses that can actually save lives. At every moment, within your body and all around you, trillions of microscopic combatants are fighting an invisible war. Countless times per second, 'good' viruses known as phages are infecting and destroying bacteria. These phages are the most abundant life form on the planet and have an incredible power to heal rather than harm. So why have most of us never even heard of them? 'The Good Virus' reveals how personalities, power and politics have repeatedly crashed together to hinder our understanding of these weird and wonderful life forms.
