Hoosiers Encouraged to Protect Against Ticks and Tick-Borne Diseases

More by this author

State Health officials urge Hoosiers to be aware and protect themselves from ticks while they are taking advantage of the warm weather outdoors.

Ticks are small, insect-like creatures that are often found in naturally vegetated areas or woodlands throughout Indiana. Ticks can transmit illnesses such as Lyme disease and Rocky Mountain spotted fever. Last year, Indiana confirmed 100 cases of Lyme disease and 34 cases of ehrlichiosis.

“When the weather stays warm, as it is in the summer, ticks are more active,” said Bryan Price, State Entomologist. “It’s important to know that ticks can transmit several diseases and that all ticks should be considered infectious.”

When entering a grassy or wooded area where ticks are often present, the best way to prevent tick-transmitted diseases is to wear a hat, long-sleeved shirt and light-colored pants, with the shirt tucked in at the waist and the pants tucked into socks. The use of repellents provides even more protection.

Insect repellents containing DEET or picaridin can be sprayed on both skin and clothing to repel ticks and other insects. People who expect to be exposed to ticks for extended periods of time should use products containing permethrin on their clothing, but not on bare skin. Permethrin is an insecticide that kills ticks and other insects on contact.

After leaving a grassy or wooded area, people should check for ticks on clothing and skin. Ticks need to be attached for several hours to a couple of days before they can infect a person. Pets should also be checked for ticks after being outside.

“Ticks can be safely removed even if they are attached to your skin,” said Price. “Ticks can be removed with either tweezers or forceps by grasping the tick as close to the skin as possible and then pulling upward with steady and even pressure. It’s not a good idea to remove ticks with fingers, but if tweezers or forceps are not available, you can use tissue paper or a paper towel to prevent the transmission of any possible infection.”

If a person does become ill after finding an attached tick, he or she should see a medical provider immediately. Tick-borne diseases can all be successfully treated with antibiotics and prompt diagnosis can help prevent complications.

Common tick-related illnesses include Lyme disease, Rocky Mountain spotted fever and ehrlichiosis. Lyme disease is often associated with a persistent, slowly expanding blotchy red rash which is usually fainter at the center than at the edges, or “bulls-eye rash. Other signs and symptoms include joint pain, especially in the knees, or weakness of the facial muscles. The symptoms of Rocky Mountain spotted fever and ehrlichiosis are similar. They include a moderate-to-high fever, coupled with fatigue, muscle aches and pains, severe headaches and chills. A rash may also develop shortly after disease onset, first appearing on the arms, legs, palms of the hand and soles of the feet before spreading to other parts of the body. The rash is not present in all cases.
