May, June and July peak season for Wyoming ticks

May 28, 2013 From staff reports

State residents should avoid ticks when enjoying activities or working outdoors during warmer weather because the insects can carry and pass on disease, according to the Wyoming Department of Health.

"May, June and July are typically the peak months for Wyoming's tick populations," said Emily Thorp, WDH surveillance epidemiologist. "Tick exposure is common when we walk through, play or sit in brushy and grassy areas or handle certain animals."

In Wyoming, diseases transmitted by infected ticks include tularemia, Rocky Mountain spotted fever and Colorado tick fever.

Tularemia symptoms can include fever, swollen and painful lymph glands, inflamed eyes, sore throat, mouth sores, skin ulcers and diarrhea.

If the bacteria are inhaled, symptoms can include abrupt onset of fever, chills, headache, muscle aches, joint pain, dry cough and progressive weakness and pneumonia.

Initial RMSF symptoms may include fever, nausea, vomiting, muscle pain, lack of appetite and severe headache. Later signs and symptoms may include rash, abdominal pain, joint pain and diarrhea. RMSF patients often require hospitalization.

Colorado tick fever usually causes fever, headache, muscle and joint pain, and, occasionally, a rash.

One case of tularemia was reported to WDH in 2012; one case in 2011; and three in 2010, including one that was fatal. In 2012 there were two RMSF cases and one CTF case reported.

Tips to avoid ticks, diseases they carry

- Wear light-colored clothing to make it easier to see ticks crawling on clothing.

- Tuck pant legs into socks.

- Apply insect repellents such as those containing 20 percent or more DEET and/or picaradin.

- Upon return from potentially tick-infested areas, search yourself and children for ticks and remove if found.

- Check pets for ticks; veterinarians can recommend tick control products.

Added precautions to help reduce tularemia risk include:

- Avoid bathing, swimming or working in untreated water and avoid drinking untreated water.

- Avoid handling rabbits, squirrels or other animals that appear sick.

- Wear rubber gloves when skinning animals, especially rabbits and squirrels; skin animals in a well-ventilated area.

- Wash hands thoroughly with soap and water after handling sick or dead animals.

- Cook meat thoroughly before eating, especially rabbit and squirrel.
