Within a few weeks, Friedheim left school with swollen joints and irritable bowels. He tested negative for spotted fever rickettsioses, one of a group of diseases including Rocky Mountain spotted fever, the most commonly diagnosed tick-borne illness in North Carolina. In , North Carolina had a total of confirmed or probable cases of spotted fever rickettsiosis , Lyme disease or ehrlichiosis in , according to the state Department of Health and Human Services.
Of those, , or 12 percent, were ehrlichiosis. But a new paper out of University of North Carolina-Chapel Hill suggests that ehrlichiosis is far more common than previously thought. The study examines records of patients who had been tested for tick-borne illness during summer These three tick-borne illnesses require different tests, and patients reviewed were not tested for ehrlichiosis.
Lone Star ticks transmit ehrlichiosis, while dog ticks carry spotted fever rickettsioses. Almost 80 percent of patients originally took a spotted fever rickettsiosis test, but only a third took an ehrlichiosis test. Even though Friedheim tested negative for spotted fever rickettsiosis, he nonetheless received a prescription for doxycycline, the antibiotic used to treat many tick-borne illnesses. Humans slowly create antibodies in response to a tick bite, which is why those first tests can come back negative, Boyce said.
The Centers for Disease Control and Prevention recommends patients take another test four to six weeks later to confirm or receive a diagnoses, after their bodies have ramped up the antibodies in response to a tick infection. Once produced, those antibodies remain in the body, Boyce said.
That person will always get a positive acute test, and only the second, later test will reveal a new infection. In order to be recorded as a confirmed case of ehrlichiosis and for this case to be reported to CDC:. This lack of follow-up testing means that public health officials have a hard time tracking incidences of tick-borne diseases. To date, the CDC only requires DHHS to report some, but not all tick-borne diseases, including cases of ehrlichiosis, spotted fever rickettsiosis and Lyme.
That means no one knows how many cases of STARI, a disease similar to Lyme, or alpha-gal allergy, the red-meat allergy carried by the lone star tick , have occurred in North Carolina, Herman-Giddens said.
A recent survey of households in Chatham County supports the claim that tick-borne illnesses are underreported. Shannon Godbout of the county public health department emailed that 8. Though Chatham has one of the highest rates of reported tick-borne diseases in the state, these results imply that the number of tick-borne illnesses could be higher than the confirmed North Carolina cases in At the state lab, patient data goes through both ehrlichiosis and spotted fever tests.
DHHS gives recommendations, but medical providers choose which tests to run if they use a private lab. Boyce suggests creating and using a standard tick panel to test all three diseases, which start with similar cold-like symptoms. After going to urgent care several times in Lexington, Va.
Half of his face was paralyzed, leaving him unable to talk or eat, when doctors at Carolinas Medical Center — Mercy diagnosed him in September with meningitis caused by Lyme disease bacteria. In , the CDC reported Lyme disease was spreading south and was particularly prevalent in Virginia. As far back as , entomologists from Yale found Lyme disease increasing in North Carolina. Boyce said that means we can expect more tick-borne illnesses. Friedheim, whose Lyme disease flared up again this summer, urges anyone suspecting a tick-borne illness to seek medical attention.
He thinks the tick bite gave him Lyme disease. Correction: This story has been altered to note that the NC DHHS tests for some other tick-borne diseases beyond erlichiosis, Lyme and spotted fever rickettsiosis. Republish This Story.

It is a complex area. In addition, there are several other tickborne diseases that are not yet reportable and not mentioned in the article — Borrelia miyamotoi, Heartland virus 1 case in North Carolina so far , and Bourbon virus. These latter two are transmitted by the Lone Star tick. Lyme disease can be acquired now in many parts of the state. This article was the basis for a good conversation around tick borne illness perception and prevention.
