Leptospirosis is a serious, potentially deadly infection found worldwide that’s caused by multiple strains of spirochete bacteria. A zoonotic disease, leptospirosis can be transmitted between animals and humans.
Lyme disease is transmitted through the bite of an infected tick. Four species of ticks have been shown to transmit Lyme disease, but the most common culprit is the deer tick (black-legged tick). Deer ticks and those carrying Lyme disease are common in the Eastern United States and can be found in nearly all warm, damp areas, including northern climates in the summer months.
