Lyme disease: infection with a bacterium, borrelia burgdoferi which is transmitted by the bite of a tick, a true zoonosis (zoonotic disease) starts in wild populations and spreads to us. Bacteria deposited into skin and leaving the site causes rash. Cognitive abilities can be lost over time. Lyme awareness = lyme prevention: not all ticks are infected. 50% of adult ticks (oct/nov/april: ticks need 36-48 hours of contact before transmitting pathogens, early lyme disease can usually be treated with antibiotics, avoid tick bites. Personal protection: clothing, repellants (deet), and acaricides (permethrine) Reduce source/habitat (clear lawn debris: remove ticks that have bitten/attached. Unattached or dead ticks do not transmit pathogen: get diagnosed if you"ve (cid:271)ee(cid:374) (cid:271)itte(cid:374) Chronic lyme disease (late stage lyme, persistent lyme infection: lyme disease is underdiagnosed, some human borrelia infections are not treated by antibiotics, left undiagnosed, borrelia infections lead to various forms of debilitating disease.
