Summer is the season for getting outside, doing yard work, gardening, camping, hiking, etc.
It is also the season for ticks. These small insects feed on the blood of mammals, and can transmit disease to horses, sheep, cattle, dogs, - and humans. There are over 800 species of ticks, of which only 100 are known to transmit disease to humans. Therefore, most tick bites do not cause illness. Fever, chills, headache, and general muscle aching are the most common complaints.
