Tularemia
It is caused by a highly infectious bacterium that is transmitted by a dog, wood, or lone star ticks. There are several types of tularemia, but two of the most common forms associated with tick bites are ulceroglandular and glandular, according to the CDC.
Tularemia does not occur as frequently as other tick-borne diseases, but it has been on the rise. Only 134 cases were reported in 2004, which grew to 230 in 2016. Tularemia can occur across the U.S., but tends to be more common in central parts of the country, the CDC report states.
Powassan virus
Also known as POW, this disease is transmitted by the bite of an infected tick and can not be spread directly from person to person. Its signs include fever, headache, vomiting, weakness, confusion, loss of coordination, difficulty speaking, and seizures.
Powassan virus is rare in the U.S. Only one case was reported each year between 2004 and 2006. However, that number jumped to 22 cases in 2016, the highest it has been in 13 years. Most cases have popped up in the Northeast or Great Lakes regions of the U.S.
