Fallen Leaf Campground to close next week for pesticide treatments

Fallen Leaf Campground will be closed starting Monday, June 27 so county and state public health and vector control officials can start pesticide treatments to minimize the risk of plague.

The treatments are a public safety precaution after tests on 15 rodents resulted in one positive case of plague on June 20, 2016. There is minimal risk to the public at this time.

The campground will close at 7:00 p.m. Monday but all campers will need to check out by noon. The U.S. Forest Service Lake Tahoe Basin Management Unit expects it to reopen by Friday, July 1 in time for the holiday weekend.

Officials will dust all rodent burrows with a pesticide to reduce the number of fleas that can carry plague. The pesticide to be used, DeltaDust, is a pyrethroid that has minimal effects to people or pets with direct contact. Pyrethroids are a man-made version of pyrethrins, which are natural
insecticides made from chrysanthemum flowers.

A flea sample from a yellow-pine chipmunk collected from the southwest end of the campground tested positive for plague earlier this month. El Dorado County officials issued a news release, and the Forest Service posted signs warning visitors that plague was detected, explaining the precautions to follow and encouraging campers to report any sick or dead rodents.

Plague is naturally present in many parts of California, including at higher elevation areas of El Dorado County and is spread by squirrels, chipmunks and other wild rodents and their fleas. People may get plague if bitten by an infected flea or through close contact with an infected rodent or pet. Plague can be prevented by avoiding contact with wild rodents, and by keeping
pets away from rodent burrows. Risk of acquiring plague is very low when precautions are taken.

Symptoms of plague usually show up within two weeks of exposure to an infected animal or flea, and include fever, nausea, weakness and swollen lymph nodes. Plague can be effectively treated with antibiotics if detected early.

Tips to prevent exposure to plague include the following:
• Do not feed squirrels, chipmunks or other wild rodents.
• Never touch sick, injured or dead rodents.
• Do not camp, sleep or rest near animal burrows or areas where dead rodents are observed.
• Look for and heed posted warning signs.
• Wear long pants tucked into boot tops and spray insect repellent containing DEET on socks and pant cuffs to reduce exposure to fleas.
• Leave pets home if possible, otherwise keep pets on a leash. Do not allow pets to approach sick or dead rodents or explore rodent burrows. Protect pets with flea control products.
• Cats are highly susceptible to plague and can pose a direct threat to humans. Keep cats away from rodents. Consult a veterinarian if your cat becomes sick after being in contact with rodents.
• If you get sick after being in an area where plague is known to occur, consult a physician and tell them you may have been exposed to plague.
State and local health officials will continue to monitor plague-prone areas.
