Vector-borne diseases are illnesses that are transmitted to pets and humans through vectors such as ticks, fleas and other such creatures. When these diseases are transmitted to humans many serious symptoms can result including debilitating fatigue and mysterious medical conditions. In this program we'll take viewers into the laboratories that work with vector-borne disease and see that much of the distress comes from bacterial infections-in particular one known as bartonella. We'll see how pet owners can protect their beloved cats and dogs from these vectors. We'll also take viewers into the woods where ticks and fleas live and discover how we can better prevent these dangerous infections.
