"4 Most Common Virginia Ticks"
The four most common ticks in Virginia that are encountered by humans are the lone star tick, the American dog tick, the brown tick, and the deer tick. The lone star tick is found predominately east of the Blue Ridge Mountains. The American dog tick is found predominately west of the Blue Ridge Mountains. The brown dog tick can be found throughout Virginia but tends to be uncommon. The deer tick is uncommon also and is found primarily in the northern and eastern sections of Virginia.
The brown dog tick is not known to carry any disease in Virginia. Both the lone star tick and the American dog tick are potential carriers of Rocky Mountain Spotted Fever (RMSF). The deer tick is a potential vector of Lyme disease and has been implicated in the transmission of ehrlichiosis. In any case of suspected tick transmitted disease, consult with a physician.
A tick needs to be attached for four to six hours in order to transmit RMSF to its human host. The first symptoms noticed are usually severe headache, chills, fever, muscle aches, nausea, vomiting, and other flu-like symptoms. These first symptoms usually start 2 to 12 days after the tick bite. By the third day after the bite, a red rash develops on the wrists and ankles, in most cases, and often spreads to the entire hand or foot. A blood test is needed to confirm the disease, and early use of antibiotics has a very high rate of cure.
Lyme disease, Borrelia burgdorferi, initially develops as an oblong rash, usually 2 or more inches in size, with a clear center that develops at the site of the tick bite, although only 70% of people develop this symptom. The tick needs to be attached for 36 hours to transmit the disease. At a later time people usually develop flu-like symptoms such as nausea, headache, fever, and general stiffness of the neck joints. Chronic symptoms of a small percentage of untreated people include arthritis and nervous system complications.
All ticks have eight legs in the adult stage, but have six legs as newly hatched larvae. Small ticks of all species are called seed ticks, a common name that does not refer to one particular species.
The following methods of prevention are recommended by the Virginia Department of Health.
Ticks are best removed with tweezers or by wrapping the tick in tissue paper and pulling out with fingers. Do not twist or jerk, and pull slowly to avoid leaving the mouthparts in the wound. Do not use nail polish, petroleum jelly, alcohol, or hot matches to remove the tick. Wash the wound with an antiseptic after the tick is removed. Kill the tick in rubbing alcohol and keep it in a small vial for a few months in case any disease symptoms develop.
