You are an epidemiologist attempting to determine how a fever-inducing infection is being transmitted throughout a community. You identify the index case and determine that the only connection between the index case and the next patient is a dog owned by the second patient who had eaten food scraps out of the garbage can at the first patient’s home. The dog did not get sick. How would you classify the dog in the transmission route of the disease?

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. B. burgdorferi can survive without iron, as it uses manganese in place of iron-sulfur clusters in its enzymes. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system.

What type of reservoirs are involved in Lyme disease transmission?
