ID#:9535
Description:This photograph depicted a dorsal view of an immature, or nymphal, "lone star tick", Amblyomma americanum. Nymphal ticks are much smaller than adult ticks, and people might not notice a nymph until it has been feeding for a few days. Nymphs are, therefore, more likely than adult ticks to transmit diseases to people.
Symptoms and Diagnosis:

Persons who have been bitten by a lone star tick, A. americanum, and who develop a red, expanding rash with central clearing, known as “erythema migrans”, headache or myalgia with fever, should see their physician. The Centers for Disease Control and Prevention (CDC) is interested in obtaining samples from such patients under an Institutional Review Board-approved investigational protocol

Prevention and Treatment:

Prevention measures similar to those for the Lyme disease vector will reduce your exposure to infected ticks. See Lyme Disease Prevention and Control for information on how to:

- avoid tick habitats,

- reduce tick abundance,

- use personal protection equipment, and

- check and remove ticks.
