The Centers for Disease Control recommends these steps to prevent anaplasmosis and other tick-borne diseases:
• Avoid wooded and bushy areas with high grass and leaf litter.
• Walk in the center of trails.
• Use repellents that contain 20 to 30 percent DEET (N, N-diethyl-m-toluamide) on exposed skin and clothing for protection that lasts up to several hours. Always follow product instructions. Parents should apply this product to their children, avoiding hands, eyes and mouth.
• Use products that contain permethrin on clothing. Treat clothing and gear, such as boots, pants, socks and tents. It remains protective through several washings. Pre-treated clothing is available and remains protective for up to 70 washings.
• Other repellents registered by the Environmental Protection Agency may be found on the EPA’s website.
• Conduct a full-body tick check using a hand-held or full-length mirror to view all parts of your body upon return from tick-infested areas. Parents should check their children for ticks under the arms, in and around the ears, inside the navel, behind the knees, between the legs, around the waist and especially in their hair.
• Examine gear and pets. Ticks can ride into the home on clothing and pets, then attach to a person later, so carefully examine pets, coats and day packs.
• Tumble clothes in a dryer on high heat for an hour to kill remaining ticks. (Some research suggests that shorter drying times also might be effective, particularly if the clothing is not wet.)

Letterman’s experience taught many the name of the disease just when it was starting to become more common in the United States, mostly in the upper Midwest and Northeast regions.
First discovered in the country in the mid-1990s, the number of cases has increased steadily.
When Letterman got it in 2009, the Centers for Disease Control reported 1,163 cases nationally, the first time it had topped 1,000 cases. In 2010, nearly 1,800 cases were reported, more than 10 times the number from 1998.
That rapid increase has also been seen in Maine.
Ten years ago, the disease was virtually unheard of in the state, with just one diagnosed case in 2004.
Over the past decade though, the number has been climbing, especially in the past few years. In 2012, the number of cases doubled, from 26 to 52. In 2013, preliminary figures released by the Maine CDC in response to a request from the Morning Sentinel show 94 reported cases, a new high, according to state epidemiologist Dr. Stephen Sears.
In its 2012 annual report on infectious diseases, the Maine CDC said the rise highlights “the importance of awareness and prevention efforts around tickborne diseases in Maine.”
Borelli said that before anaplasmosis was recognized in the United State in the 1990s, most doctors assumed that people with the disease were actually suffering from ehrlichiosis, a very similar tickborne bacterial infection that is commonly carried by the Lone Star tick in the South.
“They’re almost identical, clinically,” he said.
Now, though, doctors recognize that the Northeast has its own unique strain of bacteria that distinguishes itself from ehrlichiosis, creating one more difference, however subtle, between the two regions.PREVENTION IS KEY
Borelli said the increase in the number of reported cases in Maine is probably at least partially a result of the increase of awareness and improved diagnostics among health care professionals.
“We’re looking for it a little bit more,” he said. “As providers get more educated on tickborne diseases, they’re going to test for it more. The more you test for them, the more you find them.”
Another factor might be the last couple of mild winters, which have been easy on the ticks that carry the disease.
But he also said many people get anaplasmosis at the same time they get Lyme disease. Since the treatment for both is the same, many cases of anaplasmosis probably go unnoticed.
When a person with Lyme disease seems to be struggling with it more than would be expected, it is often a sign that they’ve been co-infected by both bacteria at the same time.
“We don’t get too excited about anaplasma with most people,” he said. “In immunoconfident people, the infection is generally self-limited in a period of time, usually about two weeks. There’s no evidence that it causes any kind of chronic infection. That’s the good news about this disease.”
The CDC recommends that people take steps to avoid contact with ticks by staying clear of wooded and bushy areas with high grass and leaf litter and by walking in the center of trails.
It also recommends the use of tick repellents that contain DEET or permethrin on skin, clothing and items such as tents.
As soon as possible after being outdoors, bathe or shower and conduct a full-body tick check, paying special attention to the underarm, in and around the ears, inside the navel, behind the knees, between the legs, around the waist and especially in the hair. Gear and pets should also be checked.
Ticks on clothing can be killed by putting the clothes in a dryer on high heat for up to an hour.Matt Hongoltz-Hetling — 861-9287 firstname.lastname@example.org Twitter: @hh_matt
