Very good.
On prevention measures, we know that it's in the environment. There are ticks. There are animals that are the carriers of the bacteria. Ticks have a blood meal on an infected animal, become infected with the bacteria and then can transmit it. Prevention can be at the level of the animals. I think there was this example of West Nile virus, where you can use insecticides to try to kill part of the reservoir of the bacteria, which are the ticks.
But it's also prevention measures and, again, it deals with awareness. People are more aware of the possibility of being bitten by a tick. So, if you wear long sleeves, if you spray yourself with insecticide; these are ways of preventing contraction of Lyme disease. There are multiple ways that you can intervene to try to prevent the transmission of the disease. That would be my answer to your first question.
The answer to your second question, and this is a paradigm of all infectious disease, is that you have to understand the infectious organism, in this case Borrelia—how it enters the human body, how it counteracts the immune system—in order to be able to tackle it. The work that Dr. Chaconas or Dr. Moriarty is doing is to try to better understand this host-pathogen interaction. The host is the human and the pathogen is Borrelia. By having a better understanding of those interactions, it provides a way to try to counteract the effect of that bacteria.
