Tick-Borne Diseases: Recognized and Theorectical Risks Associated with Blood Transfusion
Pathogenic microorganisms transmitted by ticks have taken on expanded public health significance during the last several decades. Ticks are now recognized to transmit over a dozen diseases that are caused by a variety of pathogenic agents ranging from bacteria and protozoa to viruses . Humans have increasingly come in contact with ticks as they expand their outdoor recreational activities and move their homes to rural environments. Similarly, the reforestation of suburban neighborhoods has provided ideal habitats for transport and reservoir hosts (e.g., deer, rodents) of ticks and tick-borne diseases, further facilitating transmission to humans. During the same period, new etiologic agents of disease transmitted by ticks have emerged, while the geographic distribution of existing agents has expanded. Taken together, newly emergent tick-borne agents and those described previously pose an ongoing concern to public health.
