Tick-Borne Relapsing Fever (TBRF) in Lake Tahoe

TBRF is a bacterial infection caused by soft ticks that feed on rodents such as squirrels, chipmunks, and mice. These ticks typically live in the nests of these rodents and can bite humans if they enter the same space, especially in rustic cabins or dwellings with rodent infestations. Symptoms of TBRF include recurring bouts of fever, headache, muscle and joint aches, and nausea. If left untreated, the disease can cause serious complications.

Lyme disease is transmitted by the western black-legged tick, which is more prevalent in lower elevations and milder regions of California and Nevada. Symptoms of Lyme disease include fever, headache, fatigue, and a characteristic “bulls-eye” shaped rash. If left untreated, the infection can spread to joints, the heart, and the nervous system.

Precautions and Prevention

To prevent tick bites while visiting Lake Tahoe, it’s important to take the following precautions:

  1. Wear long-sleeved shirts, long pants, and light-colored clothing to make ticks more visible.
  2. Apply insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to clothing and skin.
  3. Conduct regular tick checks on your body, especially after spending time outdoors.
  4. Remove any attached ticks promptly and correctly to reduce the risk of disease transmission.

Regional Prevalence

While Lake Tahoe is not as heavily infested with ticks as other regions, there have been reported cases of TBRF and Lyme disease in the area. The risk of encountering ticks increases in mountainous areas, especially during the summer months when ticks are more active.
