In early July, 1863, troops from General Robert E. Leeâs Army of Northern Virginia (the Confederates) met up with a patrol of Union cavalry on the outskirts of Gettysburg, Pennsylvania. Over the next three days, this encounter grew into a turning point of the Civil War.
In the South, lone star ticks (Amblyomma americanum) can also transmit Lyme disease or a closely related illness. Ticks have four life stages: egg, larva, nymph and adult. In each stage after hatching, they suck blood from animals like mice, squirrels, birds and deer.
The most common tick-borne illness in these regions, Lyme disease is transmitted by the bite of an infected black-legged tick, commonly known as a deer tick. You're more likely to get Lyme disease if you live or spend time in grassy and heavily wooded areas where ticks carrying the disease thrive.
