Many people think of Lyme disease as a simple illness caused by the bite of an infected tick.Though a bite may be a triggering event, this perspective is simplistic and does not take into consideration the numerous issues that both the patient and doctor must consider and treat in order to attain the best possible outcomes. Furthermore, medical literature suggests that Lyme disease is a complex illness which may be transmitted by mosquito bites, blood transfusions, sexual intercourse and many other ways.
