Tick season has started again, and all reports suggest that the population of ticks has increased dramatically. Unfortunately, a higher percentage of ticks appear to be carriers of lyme disease this year, and in addition to the prospect of dogs becoming infected, the dogs tend to carry many ticks as a result of being outside in parks and yards. This increases the prospect of those in the household being bitten, even if they have not been outside. Lyme disease is rampant, and because it is difficult to diagnose, it probably accounts for more undiagnosed ailments than anything else. There is a vaccine for dogs to protect against Lyme disease, but I am not sure that this provides any benefit to humans who are bitten by infected ticks that were carried by a dog, even though vaccinated.
